SUBJECT: Contaminants of Emerging Concern in Drinking Water, 2025 Progress Update
In 2011, the Commission endorsed a new program to systematically review drinking water Contaminants of Emerging Concern (CECs) which are unregulated contaminants such as pharmaceuticals, personal care products, hormones, and other chemicals that may pose potential risks to human health and the environment. The program allows us to better organize available information on CECs in a consistent and proactive manner; engage stakeholders; prepare for future drinking water regulations; prioritize limited resources; and anticipate public inquiries regarding unregulated contaminants.
The program is timed to provide the CEC update to the Commission around the same time as the triennially mandated Public Health Goal Report for regulated contaminants. Per this schedule, CEC reports were prepared in 2013, 2016, 2019, and 2022. CECs were also considered in the Water Quality Strategic Plan, most recently published in 2024.
The list of CECs is continually growing because of improvements in analytical methods. Public concern about individual CECs can develop quickly because of CEC detection, limited information on health effects of CECs, and rapid communication (i.e., digital media). San Francisco has highly protected water supplies, but trace level detections of CECs are likely in existing or future supplies. Per- and Polyfluoroalkyl Substances (PFAS), the so-called “forever chemicals”, are an example of such CECs.
Due to the large number of CECs and the lack of specific information available about individual CECs, our CEC approach utilizes grouping and indicators. The approach is more qualitative than for regulated contaminants that have numeric water quality criteria. Our approach for grouping, screening, and prioritizing unregulated CECs to determine the need, if any, for further action was endorsed by the Commission in 2011. The 2022 CEC report reduced the number of Priority Groups from 12 to 10, including Microbial Waterborne Pathogens; PFAS; Disinfection Byproducts (Nitrosamines); Disinfection Byproducts (Other); Algal Toxins & Harmful Algal Blooms; Inorganics; Organics; Pharmaceuticals and Personal Care Products/Endocrine Disrupting Compounds/Hormones; Microplastics & Nanoplastics; and Engineered Nanomaterials & Nanoparticles. These Priority Groups are maintained in the 2025 Progress Update.
The 2025 update confirms San Francisco’s excellent water quality, with CEC’s typically not detected or very low compared to other water utilities. Monitoring data for the CEC Priority Groups show that treatment and distribution system programs are optimized for CECs. Please see the attached report for details on our CEC priorities, progress over the last three years (2022-2024), and our plan for the next three years (2025-2027).
This report was prepared by the Water Quality Division and reviewed by experts from the San Francisco Department of Public Health and Trussell Technologies, Inc. We presented our findings to the Citizens Advisory Committee (CAC) on May 27, 2025, and plan to present it to Wholesale Customers on August 20, 2025. As in the past, these stakeholders will continue to be updated every three years.

8 1.0 Introduction
This Report presents a three-year review, from 2022 to 2024, of Contaminants of Emerging Concern (CECs) in the San Francisco Public Utilities Commission (SFPUC) drinking water system. CECs are unregulated contaminants that may be detected in water and research is growing to document their sources, occurrence, removal during treatment, fate in drinking water distribution systems, and potential risks to human health and the environment. It is important to recognize that CECs are present at extremely low levels in drinking water, are unregulated, and have numerous unknowns with respect to occurrence, treatment efficacy, and risk to public health. Their mere presence in drinking water at such low levels is not in itself a reason for concern and SFPUC’s CEC approach is very proactive.
The SFPUC has approved an approach for evaluating and prioritizing CECs in drinking water to determine the need, if any, for further actions, such as water quality monitoring. The approach also provides a mechanism for documenting CEC information and engaging the customers and other stakeholders on CEC issues. CECs are an important consideration for water utilities in their aim to:
• provide safe drinking water,
• maintain customer confidence in the water supply, and • prepare for possible future regulations with additional monitoring, treatment optimization, and/or other mitigation measures.
This Report presents the implementation of the approach for CECs in SFPUC drinking water.
The objectives of this work are to:
• provide a consistent, proactive, and flexible means of organizing and prioritizing CEC activities to benefit SFPUC customers when regulatory guidelines are not available, and • enhance stakeholder engagement on CEC issues.
In 2024, the Water Quality Strategic Plan (WQSP) Update Report included a CEC focus area with actionable recommendations for achieving water quality goals that can be prioritized using defined, semi-quantitative criteria. An update on the status (as of May 2025) of the 2024 WQSP CEC recommended actions is in Table 5.
In 2022, a Report on CECs in SFPUC Drinking Water presented an in-depth update on CECs including:
• SFPUC monitoring data,
• Changes to CEC Grouping from 12 to 10 groups (see footnotes to Table 1), • Screening Evaluations of a newly consolidated 10 groups of contaminants, • Regulatory update,
• The progress made by SFPUC over six years (2016-2021), and 2025 CEC Progress Update
07/22/2025
9 • Findings from the scientific literature at that time, and • A review of recommended actions and monitoring plan for the next three years (2022- 2024).
In 2019, a Progress Technical Memorandum (TM) was issued, which discussed:
• New/revised CEC priorities,
• Emerging issues,
• Regulatory developments,
• A review of recommended actions and monitoring data,
• The progress made by SFPUC over three years (2016-2018), and • A plan for CEC monitoring for the next three years (2019 – 2021).
The 2022 and 2019 CEC documents were presented to the SFPUC Citizens’ Advisory Committee (CAC) and the Commission. This 2025 Report provides a current update encompassing years 2022 – 2024. The 2025 CEC findings have been presented to the CAC.
2.0 Approach for CEC in SFPUC Drinking Water
In November 2011, a TM was submitted to the Commission on the proposed approach for CECs in SFPUC drinking water. The approach developed was to group, screen, and prioritize the unregulated CECs to determine the need for further action and was subsequently endorsed by the SFPUC Commission in November 2011. This Report is the continuation of the same approach with improvements/refinements. The approach is summarized in Figure 1. Due to the large number of CECs (hundreds of thousands of unregulated microbial and chemical contaminants) and lack of specific information, the CEC approach utilizes grouping and indicators and is more qualitative compared to regulated contaminants that have numeric water quality criteria. The decisions are based on the latest scientific information and SFPUC monitoring data. Our approach is based on the following steps:
A. From the universe of water contaminants, regulated contaminants are separated and considered under regulatory compliance across the top of Figure 1.
B. CECs are organized in groups and a review of available SFPUC monitoring data plus a review of scientific studies is conducted by WQD staff. A screening evaluation table is prepared for each group of contaminants to summarize information and provide a basis for establishing priorities and recommended actions.
C. Expert and stakeholder (e.g., CAC) review is conducted next to evaluate the significance and prioritization of various CEC groups or individual CECs for the SFPUC drinking water system.
D. The SFPUC Commission is briefed on the findings, priorities and recommendations for CEC groups. The Report and recommendations are forwarded to the Commission for feedback, as shown on the right-hand side of Figure 1.

3.0 CEC Groups and Screening Evaluations for SFPUC Drinking Water
The Screening Evaluations of this Report remain the same from the 2022 CEC Report and include general information, context of the CEC evaluation for SFPUC (occurrence data, prior 2025 CEC Progress Update
07/22/2025
11 experience, customer concerns; etc.), diagnostic questions and answers on health, occurrence, and treatment.
The CEC Screening Evaluation determines the prioritization of CECs, which is based on the diagnostic questions answered in the screening evaluation tables that can be referred to in the 2022 Report. The four parts of this analyses are:
• Part A - Occurrence in source waters in general and in SFPUC’s system (based on watershed and source water protection and available SFPUC monitoring data). • Part B - Occurrence after treatment and distribution in SFPUC’s system (infectivity of pathogens or presence of chemical contaminants) based on effectiveness of treatment in general, assessment of current treatment and available SFPUC monitoring data. • Part C – CEC prioritization – current assessment at SFPUC based on available scientific studies, current treatment and available SFPUC monitoring data. • Part D - Health effects from scientific studies in general and likely future U.S. or State regulations.
The proposed CEC groups and priorities are presented in Table 1. No changes were made to the 2022 priorities. Some Per- and Polyfluoroalkyl Substances (PFAS) contaminants are now regulated by the United States Environmental Protection Agency (USEPA):
• Perfluorooctanoic acid (PFOA)
• Perfluorooctane sulfonic acid (PFOS)
• Perfluorohexanesulfonic acid (PFHxS)
• Perfluorononanoate (PFNA)
• 2,3,3,3-Tetrafluoro-2-(heptafluoropropoxy)propanoate (Hexafluoropropylene oxide dimer acid (HFPO-DA) or GenX chemicals)
• Perfluorobutane sulfonate (PFBS)
These PFAS are not discussed in this report as part of the PFAS priority group. 2025 CEC Progress Update

5.0 2025 Update Overview
The 2022 Report was a full review that is conducted every six years (2022, 2028, etc.) with progress updates including review of emerging issues conducted every six years (2025, 2031, etc.). This 2025 CEC Progress Update includes:
• A review of recommended actions and monitoring data (progress from 2022 to 2024), • Regulatory developments,
• Emerging issues, and
• A plan for CEC monitoring for the next three years (2025 to 2027).
6.0 Recommended Actions and Monitoring Data
6.1 Microbial Waterborne Pathogens
Microbial contaminants are a high priority for SFPUC due to their health significance in general.
In the U.S., nearly 82,000 hospitalizations occur annually at a cost of $1.3 billion per year for eight diseases associated with microbial waterborne pathogens (Adam et al., 2017). Some microbial contaminants are also prone to carry antimicrobial resistance genes (AMR), which adds an extra layer of difficulty for removal or inactivation.
To mitigate risk posed by microbial pathogens, from 2022 to 2024, SFPUC took several actions.
SFPUC participated in the WRF Legionella research (WRF Project #5156 – Occurrence of Legionella pneumophila in Drinking Water Distribution Systems), the Partnership for Safe Water (PSW) program, improved localized disinfection practices including bacteriological testing after low pressure and outage events, improved sanitary construction best management practices (BMPs), met flushing and reservoir cleaning goals, limited nitrification for secondary disinfectant residuals management, and completed capital improvements to maintain and improve water treatment assets within the local, retail distribution system. These programs all help to optimize the performance and control of microbial pathogens in the San Francisco Water System (SFWS) distribution system and to meet turbidity removal standards for our water treatment plants (WTPs).
The PSW program is based on an initial self-assessment and subsequent action plan to improve various components of treatment plant operation. The SFPUC has also applied various practices to prevent entry and regrowth of microbial contaminants, such as updating our sanitary construction BMP protocol and additional construction measures for new water mains in proximity to sewer lines, initiated bacteriological sampling in response to low pressure and outages in compliance with Revised Total Coliform Rule (RTCR), trained staff on new applicable regulatory developments and best practices, renovated and started up a chlorine 2025 CEC Progress Update

15 booster station at the 180 million gallon Sunset Reservoir, upgraded twelve 10 million gallons per day mechanical mixers to facilitate chlorine boosting and minimize detention time in our reservoirs, added an additional seven mechanical mixers to our reservoirs, studied conveyance and treatment improvements at Forest Hill, McLaren, LaGrande tanks and Southern Sutro pressure zones, met dead end flushing and reservoir cleaning goals, employed a Cross- Connection Control Program, and achieved significant reductions in consumer complaints.
In 2025, SFPUC will expand capital projects to improve distribution water quality, pilot test a chloramine booster facility, renovate and startup secondary chlorine stations in lieu of removing reservoirs from service, and make other improvements to maintain a chloramine disinfectant residual in anticipation of the upcoming Microbial and Disinfection Byproduct (M/DBP) rules.
In addition, SFPUC participated in a WRF occurrence study (#5156) as a utility partner on Legionella in distribution systems. WRF published the final version of this report in September 2024, and it concluded there were no Legionella detected in the SFPUC distribution system.
SFPUC will continue to participate in WRF occurrence studies as appropriate, such as an upcoming project (#5301) titled “Integrating Requirements, Drivers, and Technologies for Enhanced Distribution System Water Quality Monitoring”.
As indicated in Table 6 and detailed in Appendix B, from 2022 to 2024, SFPUC experienced a low frequency of total coliform (TC) positives in both the San Francisco Regional Water System (SFRWS) and the SFWS. From 2022 to 2024, in the SFRWS there were only ten TC positives out of 6,015 samples collected (0.17%) and in the SFWS there were only five TC positives out of 11,671 (0.04%). The regulations allow for 5% of monthly samples to be TC positive. The very low number of TC positives is an indicator of effective multibarrier treatment, disinfectant residual management, and other distribution system programs. In addition, there were zero fecal/E. coli positives in both the SFWS and SFRWS across all three years.
6.2 PFAS (Per- and Poly-fluoroalkyl Substances)
There are 23 PFAS that are listed on the UCMR5 that are not regulated, and thousands of PFAS that are neither on the UCMR5 nor regulated. Despite the recent PFAS regulations released by USEPA for six PFAS (PFOA, PFOS, PFHxS, PFNA, GenX, and PFBS), SFPUC continues to implement strategies for unregulated PFAS, including post-fire monitoring of fire retardants and groundwater sampling. As summarized in Table 6 and tabulated in Appendix C, SFPUC sampled for the 23 unregulated PFAS from 2023 to 2024 as part of the UCMR5 sampling and did not detect any PFAS.
6.3 DBPs – Nitrosamines
SFPUC monitored five of six nitrosamines on CCL5 (NDEA, NDMA, NDBA, NDPA, NPYR, and NMEA) at ten locations, including at point-of-entry locations and in the distribution system.
To prevent the formation of nitrosamines in our distribution system, SFPUC optimized its treatment and minimized polymer use. SFPUC will continue to voluntarily monitor nitrosamines in our drinking water. In the future, SFPUC intends to add NDPhA and NMOR to our semiannual monitoring program and plans to establish baseline monitoring prior to indirect potable reuse.
2025 CEC Progress Update
07/22/2025
16 As indicated in Table 6 and detailed in Appendix A, SFPUC conducted a single nitrosamine sampling event between 2022 and 2024. Samples at nine locations (four SFWS and five SFWRS) were collected on May 2, 2022. All six nitrosamines on CCL5 registered as non-detect at all locations, except for NDBA, which recorded a single value of 2.6 ng/L at the SFWS University Mound System #09 (UMS #09) sampling location. NDBA was detected in 1 of 9 samples (11%) and there were no detections of the other five nitrosamines. NDBA does not have an MCL, Notification Level (NL), or Public Health Goal (PHG).
6.4 DBPs – Other Than Nitrosamines
There are 23 unregulated DBPs on CCL5. SFPUC implemented several practices to reduce the formation potential of these DBPs. A security fence was installed at the Moccasin Reservoir to invest in source water protection. An ozone system at Sunol Valley Water Treatment Plant (SVWTP) to remove taste & odor compounds and other organics is currently under construction and is anticipated to be online in May 2029.
From 2022 to 2024, SFPUC monitored bromide and chlorate in our drinking water system. The data recorded for these constituents are summarized in Table 6 and shown in Appendix A.
Bromide is a precursor to bromate and other brominated DBPs and is naturally present in drinking source waters. From 2022 to 2024, bromide was detected 156 times out of 239 collected samples (65%). With a focus on the Harry Tracy Water Treatment Plant (HTWTP) and SVWTP influents, San Andreas Reservoir, and Calaveras Reservoir, which are current and future influents to ozonation systems, bromide concentrations did not exceed 50 μg/L, a low level for drinking source waters. Therefore, there is little current concern for elevated levels of brominated DBP formation in the SFPUC drinking water system.
Chlorate is a DBP listed on CCL5 and a common minor contaminant of sodium hypochlorite (i.e., bleach), a disinfectant used by SFPUC. During the last 3-year period, chlorate was detected 65 times out of 79 collected samples (82.3%); of these 65 chlorate detections, 2 were above the California NL of 800 μg/L (2.5%). On September 6, 2022, a chlorate concentration of 990 μg/L was measured at the Early Intake Tank Outlet from the Early Intake Kitchen, and a chlorate concentration of 840 μg/L was measured at the SVWTP treated water effluent. The Early Intake value is considered to be an outlier since it is sourced from a protected watershed that has not been chlorinated. However, on September 29, 2022, chlorate notification level exceedance notices were sent to Early Intake users, SFPUC Commissioners, and Tuolumne County Board of Supervisors. Additionally, the SVWTP treated water effluent was blended with Hetch Hetchy water, resulting in water quality at Irvington Portal (IP) being below the NL.
Due to increased public and regulatory scrutiny, SFPUC is considering implementing monitoring plans for iodide, total organic nitrogen (TON), total organic halogen (TOX), haloacetonitriles (HANs), haloacetaldehydes (HALs), and haloacetamids (HAMs). SFPUC will consider evaluating the effects of wildfires, nitrification, potable reuse, and algal blooms on unregulated DBP formation through future research projects.

17 6.5 Algal Toxins & Harmful Algal Blooms (HABs)
Vulnerability of SFPUC surface water supplies to algal toxins is low to medium for local water sources and negligible/low for the Hetch Hetchy supply. SFPUC treatment plants’ influents/effluents are regularly monitored for the presence of algal toxins, which have not been detected in drinking water. SFPUC has a comprehensive algal management program and an algal toxin response plan in the event of algal toxin detections in our drinking water. Algal toxins are considered medium priority since alga types and levels and algal toxin concentrations could change over time due to climate change or other environmental factors (SFPUC, 2022).
SFPUC has prepared and updated multiple reports on algae management and algal toxins, including the Algae Monitoring and Mitigation Plan (AMMP) in 2019, the five-year (2016 to 2020) sanitary surveys for the Alameda and Peninsula watersheds, and the annual sanitary surveys for Hetch Hetchy Water Supply. Notably, recent inspections of the Hypolimnion Oxygenation Systems (HOSs) in the Calaveras and San Antonio Reservoirs have revealed that their diffusers need to be replaced to increase oxygen supply and minimize future algal blooms.
These upgrades are currently planned but have not been implemented. Additionally, as was mentioned in the previous subsection, ozone treatment is being added to SVWTP. This new treatment would also help reduce algal toxins; while algal toxins are not typically detected at WTP influents, further climate change could result in some occurrence at WTP intakes. The HTWTP, a direct filtration plant with pre-ozonation, has effective treatment barriers to remove or inactivate algal toxins.
Cyanotoxins listed on CCL5 (anatoxin-a, cylindrospermopsin, microcystins, and saxitoxin) are analyzed routinely by SFPUC’s Millbrae Laboratory using the Cyanotoxin Automated Analysis System (CAAS). Millbrae Laboratory is certified under SWRCB’s Environmental Laboratory Accreditation Program (ELAP) to analyze total microcystins. Millbrae Laboratory also performs saxitoxin analysis for the monitoring process, but there is no ELAP certification for saxitoxin.
Table 6 and Appendix A each provide further details on the sampling data for these constituents from the years 2022 – 2024. Microcystins are further divided into the following subcategories:
total microcystins, MC-LA, MC-LF, MC-LR, MC-LY, MC-RR, and MC-YR.
In SFPUC’s source water reservoirs and treatment plant influents and effluents from 2022 to 2024, there were 55 detections for total microcystins out of 745 samples (7.4%), 4 detections for cylindrospermopsin out of 37 samples (10.8%), and 2 detections for saxitoxin out of 27 samples (7.4%). There were no detections for MC-LA, MC-LF, MC-LR, MC-LY, MC-RR, MC-YR, and anatoxin-a.
The USEPA issued Drinking Water Health Advisories (HAs) for total microcystins and cylindrospermopsin in June 2015 to address illness from algal blooms. For children less than 6 years old, the total microcystins HA is 0.3 μg/L and for cylindrospermopsin, the HA is 0.7 μg/L in drinking water. For other population subgroups, total microcystins HA is 1.6 μg/L and cylindrospermopsin HA is 3.0 μg/L in drinking water. From 2022 to 2024, 41 detections for total microcystins registered greater than 0.3 μg/L (5.5% of samples) and 13 detections registered greater than 1.6 μg/L (1.7% of samples). In addition, 2 detections for cylindrospermopsin registered greater than 0.7 μg/L (5.4% of samples) and 0 detections registered greater than 3.0 μg/L (0% of samples). However, these detections for total microcystins and cylindrospermopsin 2025 CEC Progress Update

18 were primarily received from samples taken at Calaveras Reservoir and not in finished drinking waters.
6.6 Inorganics
SFPUC monitored several inorganic constituents in our drinking water system from 2022 – 2024, including boron, cadmium, lithium, manganese, strontium, vanadium, and zinc. Lithium was included in UCMR5 monitoring in 2023 and 2024. These monitoring data are referenced in Table 6 and summarized in Appendices A and C.
Boron registered 33 detections out of 48 samples (69%), cadmium registered 0 detections out of 95 samples (0%), lithium registered 0 detections out of 19 samples (0%), manganese registered 705 detections out of 1065 samples (66%), strontium registered 63 detections out of 63 samples (100%), vanadium registered 4 detections out of 10 samples (40%), and zinc registered 15 detections out of 60 samples (25%).
A raw water sample from Pond F3E in March 2022 (1300 μg/L) and one sample in April 2023 (1760 μg/L) showed elevated boron. In addition, 19 samples collected at 3 locations (SVWTP Raw Calaveras, SVWTP Raw San Antonio, and HTWTP Raw) showed elevated manganese for surface water. Similarly, the finished drinking water that originates from these raw water sources will comply with the manganese MCL and NL. Cadmium, strontium, vanadium, and zinc were either not detected or did not exceed any water quality guidelines.
6.7 Organics
SFPUC monitors regulated and unregulated SOCs and VOCs in surface water, groundwater, and drinking water. Monitoring results of SOCs were below detection limits. Monitoring results of VOCs for most analytes were below their detection limits. SFPUC has waivers for many regulated SOCs that are pesticides based on past non-detects.
Tetrachloroethylene and carbon tetrachloride were detected in some of SFPUC's groundwater wells. These wells currently are not in operation; however, the SWRCB has approved blending as a treatment strategy for these two contaminants. SFPUC did not conduct any monitoring of unregulated pesticides and unregulated industrial chemicals between 2022 – 2024.
In 2018 under the UCMR4, trace detections of quinoline (0.02 to 1.5 μg/L), a VOC, was found in the Sunset Supply Line at Balden Valve Lot, at Lake Merced, and Sunset Reservoir. Quinoline is a coal-tar lining derivative. No quinoline sampling was done between 2022 to 2024; however, SFPUC is removing coal tar lining and replacing it with cement mortar lining on upcoming pipeline rehabilitation projects. Currently in design, the Crystal Springs Pipeline (CSPL) No. 2 Reach 5 Rehabilitation project will remove 3.8 miles of coal tar lining on the 60-inch diameter welded steel pipe between Millbrae Yard and Baden Valve Lot. The project is expected to be completed by 2027. Similarly, the CSPL No. 2, Reaches 2 and 3, Rehabilitation project is currently in the design phase; it includes relocating 1.5 miles of pipeline to the decommissioned CSPL No. 1 alignment and relining 2.2 miles of coal tar enamel lined 60‑inch WSP, stretching between Crystal Springs Pump Station (CSPS) and the Bellevue Valve Lot. This is expected to be completed by 2028.
2025 CEC Progress Update
07/22/2025
19 As was mentioned in a previous subsection, ozone treatment is being added to SVWTP. This new treatment would also help reduce organic constituents. Additionally, SFPUC requires construction project contracts to specify National Sanitation Foundation (NSF) 61 materials for the interiors of tanks, pipelines, and other drinking water infrastructure. Finally, SFPUC conducts periodic soak tests to ensure materials are installed properly. These items are ongoing and will continue to be implemented to reduce organic contaminant concentrations in SFPUC drinking water.
SFPUC’s organic constituent monitoring data for the years 2022 – 2024 are included in Appendix A. SFPUC conducts unregulated organics monitoring in source and drinking water for VOCs and SOCs.
6.8 PPCPs/EDCs/Hormones
As was mentioned in a previous subsection, ozone treatment is being added to SVWTP and is already present at HTWTP. This treatment helps reduce PPCPs, EDCs, and hormones.
As SFPUC source waters are not impacted by wastewater discharges, PPCPs, EDCs, and hormones were not expected to be present in SFPUC’s protected watersheds. This was confirmed in an earlier, comprehensive research project (Snyder, 2008) and by extensive sampling and analysis performed by SFPUC in 2019. In a major investigative effort, all SFPUC source waters were analyzed for over 100 PPCPs, EDCs, and natural and synthetic hormones and all values from these analyses were below detection limits (SFPUC, 2022). However, future alternative water sources need to be monitored for this group of CECs. Once water reclamation is implemented in SFRWS and SFWS, SFPUC plans to monitor PPCPs, EDCs, and hormones with regards to this practice. Additionally, when SFPUC’s groundwater wells are operating at full design production rates, SFPUC plans to implement groundwater monitoring for PPCPs, EDCs, and hormones. SFPUC expects this well monitoring to occur in 2028.
As indicated in Table 6 and detailed in Appendix A, from 2022 – 2024, SFPUC conducted sampling for 9 PPCPs/EDCs/hormones at B Street Well, Mission Well, and Serramonte Boulevard Well. All PPCPs/EDCs/hormones were non-detect.
6.9 Microplastics & Nanoplastics
SFPUC does not currently monitor for microplastics and nanoplastics in our source waters.
However, analyses for these contaminants are planned in the near term. The SWRCB is currently finalizing a microplastics sampling protocol that will require agencies to monitor their source waters for microplastics. In tandem with this development, laboratories will become accredited to analyze for microplastics. Once these developments have occurred, SFPUC anticipates starting to monitor for microplastics in 2026 at various raw water sampling locations and include these findings in the 2028 CEC report.
6.10 Engineered Nanomaterials & Nanoparticles
Engineered nanomaterials and nanoparticles are a low priority for SFPUC since water sources are in protected watersheds and occurrence of these CECs is unlikely. Because of this, SFPUC will continue to monitor national or state surveys when appropriate, maintain source water 2025 CEC Progress Update
07/22/2025
20 protection, and track regulatory developments and publications related to these constituents, but not currently sample for them.
7.0 Regulatory Developments
This section covers regulatory developments for former and current CECs during the reporting period, including M/DBPs, PFAS, perchlorate, trihalomethanes (THMs), haloacetic acids (HAAs), manganese, Cr(VI), Safe Water Drinking Act (SDWA) regulatory documents, and detection limits for the purposes of reporting (DLRs).
7.1 M/DBP
The SDWA requires USEPA to review all National Primary Drinking Water Regulations (NPDWRs) every six years and revise them if needed. In January 2017, as part of the USEPA’s third Six-Year Review, they identified eight NPDWRs as candidates for revision: chlorite, Cryptosporidium, haloacetic acids, heterotrophic bacteria, Giardia lamblia, Legionella, total trihalomethanes, and viruses (USEPA, 2025c). Considering that changes to regulations may have unintended consequences, it is important to consider how changes in disinfection practice may impact the formation of DBPs. Because of this, USEPA is also evaluating unregulated DBPs as part of their analysis, such as chlorate and nitrosamines. The proposed M/DBP rule revisions are due to be released in July 2025, and the final rules are expected for September 2028. The USEPA may delay the proposed M/DBP revisions for a year or more.
7.2 PFAS
In 2021, USEPA released the final determinations for the Fourth Contaminant Candidate List (CCL4), which included two PFAS – perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) (USEPA, 2025a). This development was followed up in 2023 with the proposal of the PFAS NPDWR, which expanded its regulatory scope to include perfluorohexanesulfonic acid (PFHxS), perfluorononanoic acid (PFNA), hexafluoropropylene oxide dimer acid (HFPO-DA or GenX), and perfluorobutanesulfonic acid (PFBS). Following a comment and review period, USEPA finalized the NPDWR for these six PFAS on April 10, 2024. PFOS has an MCL of 4 ng/L, PFOA has an MCL of 4 ng/L, PFHxS has an MCL of 10 ng/L, PFNA has an MCL of 10 ng/L, and GenX has an MCL of 10 ng/L. In addition, any mixture containing two or more of PFHxS, PFNA, GenX, and PFBS is regulated under a Hazard Index of 1.0. Public water systems must complete initial monitoring for these PFAS by 2027 and implement treatment solutions by 2029 if their MCLs are exceeded.
However, while these six PFAS are now regulated, there are thousands of other PFAS that are unregulated. These unregulated PFAS are discussed further in other sections of this report.
7.3 Perchlorate
Perchlorate is released into the environment as a result of propellant use. It has been found to decrease production of the thyroid hormone, which affects prenatal and postnatal growth and development, as well as metabolism and mental acuity in adults. Most recently, perchlorate regulation in California has centered around potential revision of the MCL. Per a 2017 meeting, the Division of Drinking Water (DDW) must first establish a lower DLR to gather additional 2025 CEC Progress Update
07/22/2025
21 data and then revise the MCL if the data indicated a need (SWRCB, 2024). The perchlorate DLR decreased from 4 μg/L to 2 μg/L on July 1, 2021, and then from 2 μg/L to 1 μg/L on January 1, 2024.
Concurrently with the state, a federal court order mandated USEPA to establish federal NPDWR for perchlorate in May 2023, reinstating a 2011 determination that was delayed and ultimately vacated in 2020 (USEPA, 2025b). USEPA is committed to issuing this NPDWR for perchlorate by November 21, 2025, and a final regulation by May 21, 2027.
7.4 THMs
In California, the Office of Environmental Health Hazard Assessment (OEHHA) develops PHGs for drinking water based on scientific and health-based criteria. The SWRCB then uses this information to establish MCLs that also incorporate economic and social criteria.
The USEPA established a federal MCL of 100 μg/L for a group of four THMs (bromodichloromethane, bromoform, chloroform, and dibromochloromethane), colloquially referred as Total Trihalomethanes (TTHMs), in November 1983. The MCL was then revised from 100 μg/L to 80 μg/L in January 2002. While these disinfection byproducts are regulated under this TTHM standard, they were not individually considered for possible regulation until recently. In 2020, OEHHA released PHGs for the four THMs – 0.06 μg/L for bromodichloromethane, 0.5 μg/L for bromoform, 0.4 μg/L for chloroform, and 0.1 μg/L for dibromochloromethane. No MCLs for these individual THMs have been proposed at present.
7.5 HAAs
Similar to THMs, USEPA established a federal MCL of 60 μg/L for a group of five haloacetic acids (monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monobromoacetic acid, and dibromoacetic acid), colloquially referred as HAA5, in January 2002. While these disinfection byproducts are regulated under this HAA5 standard, they were not individually considered for possible regulation until recently. On December 30, 2022, OEHHA adopted and published PHGs for the HAA5 – 53 μg/L for monochloroacetic acid, 0.2 μg/L for dichloroacetic acid, 0.1 μg/L for trichloroacetic acid, 25 μg/L for monobromoacetic acid, and 0.03 μg/L for dibromoacetic acid. No MCLs for these individual HAAs have been proposed at present.
7.6 Manganese
Manganese is a naturally occurring element that is known to cause neurotoxicity. California currently has a secondary MCL of 50 μg/L based on aesthetics. It also has an unregulated, health-based notification level, discussed below in the Emerging Issues section.
7.7 Cr(VI)
Many regulatory developments have occurred in California over the past decade for Cr(VI) (SWRCB, 2025b). Unlike chromium metal and trivalent chromium, hexavalent chromium is considered carcinogenic. As a result, the SWRCB released a Cr(VI) MCL of 10 μg/L in 2014.
However, the MCL was challenged by local advocacy groups in 2017 on the basis that its enforcement did not consider the economic feasibility of complying with such a standard. The Superior Court of Sacramento County then invalidated the MCL and asked the SWRCB to document why the MCL would be economically feasible. In 2020, the SWRCB published a 2025 CEC Progress Update
07/22/2025
22 White Paper Discussion with an economic feasibility analysis, spurring the development of an MCL for Cr(VI). The SWRCB adopted the Cr(VI) MCL of 10 μg/L on October 1, 2024. Because this MCL has been adopted, Cr(VI) is again a regulated contaminant and will not be considered further in this report.
7.8 SDWA Regulatory Documents (CCL5 and CCL6, UCMR5 and UCMR6) The SDWA requires USEPA to publish a Contaminant Candidate List (CCL) every 5 years, with the intention of gathering information on priority contaminants for regulatory decision making.
Each CCL undergoes a similar process: the draft CCL is announced and released for public comment, while USEPA consults with the Science Advisory Board (SAB). Once this feedback is received and incorporated, the final CCL is published. That final CCL then feeds the development of the draft Unregulated Contaminant Monitoring Rule (UCMR), which is a list of unregulated constituents that need to be monitored by public water systems. After sampling for three years, the water systems send back their UCMR monitoring results to USEPA, which then uses these results in tandem with the final CCL to develop the preliminary and final Regulatory Determinations. At least 24 months must pass, and then the final Regulatory Determinations are used to develop proposed and final NPDWRs.
The most recent CCL, CCL5, was finalized and published on November 14, 2022. It includes 66 chemicals, 3 chemical groups, and 12 microbial contaminants. UCMR5 was published on December 27, 2021, and requires sampling between 2023 and 2025. It is composed of 29 PFAS and lithium, which will benefit understanding of their prevalence in drinking water systems.
The following constituents in Table 3 and Table 4 were listed on the final CCL5 and UCMR5 (USEPA, 2022).

USEPA has begun working on CCL6 and UCMR6. They accepted nominations of contaminants for consideration on the draft CCL6 until April 18, 2023. Currently, they are evaluating the nominations and will soon release the draft CCL6 for public review and comment. In addition, USEPA hosted two pre-proposal webinars in April 2024 to discuss potential approaches to UCMR6. They expect the proposal for UCMR6 to be released in mid to late 2025 and for the final rule to be released in late 2026. Water system sampling will occur between 2028 and 2030.
7.9 DLRs
DDW is currently reevaluating DLRs (SWRCB, 2025a). As sample analysis technology improves, there is the potential for DLRs to be closer to PHGs, which would allow for more precise data collection for MCL development.
DDW first sent out surveys to ELAP certified laboratories to gain their suggestions and feedback regarding this approach. They then presented a preliminary proposal at a November 2022 workshop, which was followed by a pre-publication Department of Finance review in November 2023. Initially, DDW plans to focus on lowering metal DLRs, including those for antimony, beryllium, cadmium, lead, mercury, nickel, thallium; as well as establish DLRs for iron, zinc, and manganese. After they notify the public of their proposed rulemaking for metal DLRs, DDW will send out surveys to laboratories that ask about costs and their capability to analyze organic compounds. This is expected to occur in 2025.
8.0 Emerging Issues
During the reporting period (2022 – 2024), there were several drinking water contaminants that emerged as new areas of research, media coverage, and legislative action. 2025 CEC Progress Update
07/22/2025
26 8.1 Microbial Waterborne Pathogens
SFPUC prevents microbial regrowth by maintaining high chloramine residual in the SFRWS and SFWS. It should be noted that greater than historical remote work, which leads to an increase in office vacancy rates, can contribute to regrowth of opportunistic microbes due to increased water age in office buildings. As per the 2022 CEC Report recommendation, SFPUC participated in and completed the WRF Legionella pneumophila (L. pneumophila) monitoring project #5156.
The results of the WRF report suggested that the occurrence of L. pneumophila was very low, with 1% positive samples in the distribution systems of well-run utilities, with concentrations below the current level of public health concern, out of more than 9000 samples (Bartrand T.A., 2024).
The main findings of this study were: 1) a reasonable testing method was demonstrated for use by water utilities along with a protocol for responding to positive detections as a starting point for developing L. pneumophila monitoring programs; 2) a preliminary estimate of background occurrence of L. pneumophila in distributions systems was developed that utilities can use to assess their own monitoring data; 3) the report reinforces that a secondary disinfectant has limits for controlling L. pneumophila and that BMPs [compliance with Total Coliform Rule (TCR) and distribution system water quality management] are important to the management and control of L. pneumophila; and 4) demonstrated that L. pneumophila is not a concern for well-operated public utilities, but utility involvement is extremely important in helping building a system to manage L. pneumophila.
Because BMPs including risk assessments are crucial for controlling L. pneumophila occurrences and protecting public health, more data and research are needed to identify effective strategies (Burlingame et al, 2024). Industry leadership and collaboration is paramount to generate practical knowledge for protecting drinking water quality (Furst et al, 2024). As of March 2025, SFPUC continues monthly sampling for L. pneumophila in our distribution system at TCR taps, which will help in understanding BMPs for L. pneumophila control. New Jersey law will require facilities in NJ that are associated with Legionnaires’ disease cases to conduct periodic water sampling and testing at minimum for L. pneumophila (LeChevallier, AWWA, 2025).
SFPUC sampled various locations in August to October in 2022 and 2023. All 144 samples were negative for L. pneumophila. In 2024, one sample read 1 MPN/100mL, which is well below the action level of 1 CFU/1mL (or 100 CFU/100mL). The use of most probable number (MPN) or colony forming units (CFU) is dependent on the method used to detect bacteria, and both MPN and CFU are valid measurements. Therefore, these units are interchangeable and 1 MPN equals 1 CFU. Monthly L. pneumophila sampling is currently ongoing with all negative results.
Using the correct testing method is also crucial for the determination of Opportunistic Pathogens (OPs) such as L. pneumophila. Viable but non-culturable (VBNC) pathogens have attracted widespread attention since they cannot be detected with traditional methods, but they can be reactivated or resuscitated to a culturable state posing public health challenges and risks.
Furthermore, their total number is believed to be much higher than those that can be cultured.
Guo et al, 2021, detected significant quantities of viable/VBNC in full-scale drinking water treatment plants (DWTPs), confirming traditional methods are not adequate.

General Recommendations for Utilities from Project #5156 Findings.
Utilities are encouraged to implement proactive L. pneumophila management programs and routine monitoring to ensure low occurrence rates. A structured approach can help maintain water quality and reduce risks.
• Utilities should develop specific L. pneumophila management protocols. • Conduct hazard assessments to identify high-risk areas. • Implement routine, risk-based monitoring to validate management effectiveness.
General Regulatory Guidance and Data Management from Project #5156 Findings.
There is a need for clear regulatory guidance on reporting L. pneumophila detections and maintaining an analyzable database for research. This will facilitate better understanding and management of L. pneumophila risks.
• Regulators should establish consensus on reporting requirements. • A centralized database for L. pneumophila data is recommended for research purposes. • Anonymized data collection can help protect utilities while providing valuable insights.
USEPA anticipates proposing M/DBP rule revisions in 2027. In a letter to USEPA dated Dec 14, 2023, the National Drinking Water Advisory Council (NDWAC) recommended to:
• Improve chloramination practices to promote control of microbial contamination and DBP formation potential and improve overall consistency of water quality (Nitrification Control Plan; Monitor regulated DBPs before, during, and after chlorine conversion). • Develop and implement a L. pneumophila public awareness campaign targeting smaller- scale buildings to elevate improved building water quality management practices.
Antimicrobial Resistance (AMR)
Antibiotics have been a significant discovery of the 20th century, saving millions of lives from bacterial infections. Due to their overuse and misuse, microorganisms have developed AMR, which refers to the potential of microorganisms, such as bacteria, viruses, fungi and parasites, to resist the effects of antimicrobial drugs. AMR is a world-wide public health threat directly responsible for 1.27 million global deaths in 2019 and contributed to 4.95 million deaths (Antimicrobial Resistance Collaborators, 2022) and projected to lead to 10 million deaths annually by 2050 (O’Neill, 2016).
Prevention is still the best strategy to reduce antimicrobial-resistant infections and their spread globally, but to combat AMR, global coordination among governmental and nongovernmental agencies is key. The National Antimicrobial Resistance Monitoring System (NARMS) is a public health surveillance interagency partnership system that tracks antimicrobial resistance in foodborne and other enteric bacteria. Data provided by NARMS are used to develop public 2025 CEC Progress Update
07/22/2025
28 health interventions and policies to protect people from resistant enteric infections. USEPA also started a collaboration with other federal agencies on the Surface Water AMR Monitoring (SWAM) program to address this global concern. SWAM intends to increase knowledge of surface water AMR occurrence and was phased to run through 2024 (Garland et al, 2024) by developing a national-scale, quantitative assessment for AMR within surface water. The SWAM Program Report submittal is planned for late 2025 into 2026.

8.2 PFAS
The UCMR5, published on December 27, 2021, includes 29 PFAS that were monitored in public water systems from 2023 through 2025. The UCMR minimum reporting limit (MRL), which represents the lowest concentration that laboratories may report to the USEPA during UCMR monitoring, ranges from 2 to 8 ng/L. Due to their potential health effects, widespread detection, 2025 CEC Progress Update
07/22/2025
29 and environmental persistence, regulatory frameworks and PFAS management are constantly evolving (DeSilva, 2022).
Among the 29 PFAS, on April 26, 2024, USEPA established legally enforceable levels, MCLs, for six PFAS in drinking water: PFOA, PFOS, PFHxS, PFNA, and HFPO-DA as contaminants with individual MCLs, and PFAS mixtures containing at least two or more of PFHxS, PFNA, HFPO-DA, and PFBS using a Hazard Index MCL to account for the combined and co-occurring levels of these PFAS in drinking water. On May 14, 2025, USEPA has proposed to eliminate the Hazard Index and to keep only the current NPDWRs for PFOA and PFOS.
While there have not been detections of unregulated PFAS in the SFPUC system, because the regulatory climate is rapidly changing, monitoring activities should continue. Unfortunately, sampling and analysis of PFAS is very complex, since each PFAS category contains a high number of individual compounds, many of which without analytical standards (Sept et al, 2022).
The Best Available Technologies (BATs) for PFAS treatment include adsorptive technologies such as granular activated carbon (GAC) and anion exchange (AIX), as well as high pressure membrane technologies such as reverse osmosis (RO) and nanofiltration (NF). Other treatments included powder activated carbon and novel sorbent media (Canida et al, 2025). While short- chain PFAS degrade similarly to long-chain PFAS, they degrade at a slower rate, making it necessary to develop a more cost-effective treatment for short-chain PFAS which includes understanding of their degradation pathway (Reddy et al, 2024).

8.3 DBPs – Nitrosamines
Chloronitramide anion has been recently detected in 40 chloraminated drinking water samples from 10 U.S. drinking water systems at a median concentration of 23 µg/L and a maximum concentration of 120 µg/L. Chloronitramide anion is a disinfection by-product derived from 2025 CEC Progress Update
07/22/2025
30 mono- and dichloramine decomposition. Its chemical structure is characterized by one chlorine atom, two nitrogen atoms, two oxygen atoms (C-N-NO2-). The anion is very stable in drinking water and very likely present in the drinking water of all the utilities that use chloramine as a secondary disinfectant (Fairey J.L., 2024). Even though more research is needed, conditions that could affect chloronitramide levels are lower pHs and greater water age (March 2025 USEPA webinar with Fairey, J.L.).
Although the toxicity of chloronitramide is currently unknown, its similarity with other reactive nitrogen DBPs with known toxicity, such as NDMA, raises concern about its potential risks.
USEPA has developed a proprietary web application tool called Generalized Read-Across (GenRA) that allows users to use existing data from well-known substances to predict the behavior of similar but unknown substances. Through GenRA, researchers concluded that the chloronitramide anion is a potential human health concern and therefore an immediate candidate for assessment in source waters, finished drinking waters, and wastewater effluents. More research is needed to better understand its toxicity, carcinogenicity together with reproductive and developmental toxicities, and factors affecting its occurrence (USEPA Science Matters, 2024).
Suggested treatment strategies to control the formation of chloronitramide may include enhancing NH2Cl stability and quenching its products, such as NO2+, during decomposition (Fairey J.L., 2024). Point-of-use filters using activated carbon or anion exchange resin could potentially remove the chloronitramide anion from drinking water, but further research is needed to understand treatment options (March 2025 USEPA webinar with Fairey, J.L.).
While there is currently no state or federal MCL for NDMA, there are established NL and response levels in California of 0.01 μg/L and 0.3 μg/L, respectively. The NDMA PHG was also issued in 2006 at 0.003 μg/L and is currently under review, suggesting NDMA may be potentially regulated in the future (Pifer A, 2023).
In the 2022 CEC report, SFPUC noted that NDMA was the main nitrogen species–mediated DBP detected in our distribution system. While detected concentrations from 2018 to 2021 were less than the NL of 10 ng/L in the SFRWS and SFWS, there was an increase in detection frequency of NDMA from the SFRWS to the SFWS, suggesting NDMA formation in the distribution system. As a result, SFPUC has been diligently optimizing our treatment to prevent NDMA levels from exceeding the NL, including avoiding cationic polymer overfeeding during coagulation at the treatment plants, providing free chlorine contact time before chloramination, and minimizing detention time in the distribution system (SFPUC, 2022). NDMA was not detected in the 2022 to 2024 sampling results, indicating that SFPUC’s preventative practices are successful.
Park et al, 2024, determined that chlorine alone is not sufficient to form NDMA. Instead, the presence of NO3- and NH3 at pHs below 6 are critical factors in formation. Controlling these factors appears to be crucial for managing NDMA formation. 2025 CEC Progress Update
07/22/2025
31 As per 2022 Final Report recommendation, SFPUC maintained optimized treatment for SFRWS and SFWS and continue voluntary nitrosamine monitoring for SFWS. Furthermore, SFPUC is planning to add NDPhA and NMOR to the semi-annual monitoring program.

8.4 DBPs – Other than Nitrosamines
DBPs constitute a group of well-known secondary pollutants formed by the reactions of chemical disinfectants with DBP precursors during water disinfection treatment (Xiao et al, 2024). Over 600 DBPs have been detected in drinking water. Current DBP regulations include the sum of TTHM and the sum of (HAA5), including monochloroacetic acid (MCAA), dichloroacetic acid (DCAA), and trichloroacetic acid (TCAA) plus two brominated compounds, monobromoacetic acid (MBAA) and dibromoacetic acid (DBAA).
Due to their cytotoxicity and genotoxicity, selected DBPs, including haloacetonitriles (HAN), haloacetamides (HAM), haloacetic acids (HAA9, HAABr6), and iodinated trihalomethanes could be considered in USEPA’s 3rd Six-Year Review as potential candidates for regulatory revision [Microbial and Disinfection Byproducts (M/DBP) rule revisions – Proposed Rule 2027; Final Rule September 2028 (Moody, 2024)]. Additionally, the USEPA is considering a potential expansion of the Disinfection Byproduct Rule (DBPR) that could result in a shift from the currently regulated five haloacetic acids (HAA5) to nine chlorinated and brominated HAAs (HAA9), including four additional brominated compounds (Stanford et al, 2024). Brominated HAAs have been included in HAA9 because recent research has shown that they may potentially exhibit higher toxicity than their chlorinated analogues (Peterson et al, 2023). Formation of iodinated DBPs (I-DBPs) is also an emerging concern, due to their high toxicity. Naturally occurring iodide, iodate, and iodinated organic compounds are the main sources of iodinated DBPs, so the removal of iodide provides a cost-effective solution for the control of I-DBPs formation (Dong et al, 2019). Disinfection with monochloramine has been shown to promote I- DBPs formation (Liu et al., 2017). Among the I-DBPs, iodinated THMs are produced during breakpoint chlorination in iodide-containing water (Liu et al., 2018). These compounds, along with aldehydes and halonitromethanes, are currently included in the CCL5. 2025 CEC Progress Update
07/22/2025
32 Hypochlorite, especially when stored at high temperatures, can introduce DBPs such as chlorate, perchlorate, and bromate into the drinking water (Breytus et al. 2017). There was a federal court order (NRDC v. USEPA, 2023) to regulate perchlorate issued on May 9, 2023. As required by the court order, USEPA has committed to issue a proposed NPDWR for perchlorate by November 21, 2025, and a final regulation by May 21, 2027.
SFPUC has conducted monitoring for unregulated DBPs including HAA9 and HAABr6.
Measured concentrations were low relative to other utilities, and below available guidelines for chlorate and formaldehyde. Chlorate is a DBP that occurs primarily from degradation of sodium hypochlorite used in the disinfection process, and the NL is 0.8 mg/L. Measured chlorate concentrations in SFPUC treated drinking water have been below the NL with 2 exceptions, as previously discussed in Section 6.4.
Unregulated DBPs are a medium priority for SFPUC. SFPUC is planning to evaluate the effects of wildfires on unregulated DBPs formation in SFPUC system after a significant wildfire in the watershed and keep monitoring the effects of algal blooms on unregulated DBPs formation in SFPUC reservoirs.

8.5 Algal Toxins & HABs
Algal toxins are natural toxins produced by cyanobacteria and marine algae during Harmful Algal Blooms (HABs). Toxins produced during HABs are (Pinto et al, 2023):
• Cyanotoxins (e.g. microcystins, anatoxins, saxitoxin) produced by cyanobacteria preferentially in freshwater reservoirs, rivers, lakes and other sources of drinking water, representing direct hazardous potential to human health. • Phycotoxin (e.g. microcystins, cylindrospermopsin) that can accumulate in the tissues of marine organisms and consequently threaten human health.
As per the 2022 Final Report recommendation, SFPUC maintains an ongoing sampling campaign for algal toxins and, as of November 2022, started monitoring new algal toxins as listed in the final CCL5. The group of cyanotoxins in the CCL5 includes, but is not limited to:
anatoxin-a, cylindrospermopsin, microcystins, and saxitoxin. In January 2025, USEPA made preliminary determinations not to regulate cylindrospermopsin and microcystins because they do not present a meaningful opportunity for health risk reduction. Final determinations are projected for summer 2025, with analytical method validation for saxitoxins underway. The need for 2025 CEC Progress Update

8.6 Inorganics
Inorganic chemicals (IOCs) such as lithium, and manganese are medium priority CECs for SFPUC. Significant levels of unregulated IOCs are not expected to occur in SFPUC’s treated surface water due to low levels in source waters or downstream treatment facilities (i.e., filter plants) or blending strategies for groundwater (e.g., for manganese).
Several CECs in this category have had regulatory developments since the 2022 CEC report. A Cr(VI) MCL was established by the SWRCB at 10 µg/L, as discussed above, and is therefore no longer a CEC. The USEPA made a regulatory determination under CCL5 on January 15, 2025 to not regulate molybdenum. These constituents will not be discussed further in this section.
California currently has a secondary MCL of 0.05 mg/L, a NL of 0.5 mg/L, and a response level of 5 mg/L for manganese. OEHHA (2022) issued a health protective concentration (HPC) for manganese of 0.02 mg/L. On February 16, 2023, DDW proposed a revised NL of 0.02 mg/L and response level of 0.2 mg/L for manganese based on toxicological endpoints. The water industry requested DDW consult with water suppliers about the ramifications of these new limits before implementing them. The DDW has not promulgated these new limits yet.
Fluoride has both a primary and a secondary MCL. The primary MCL is 4.0 mg/L. The secondary MCL is 2.0 mg/L. It is added to drinking water sources to benefit dental health. In September 2024, a federal court ruled under the Toxic Substances Control Act (TSCA) in favor of the plaintiff in Food & Water Watch v. USEPA based on a claim that “fluoride diminishes neurocognitive health”. The Court ordered USEPA to make a regulatory response. Numerous organizations, including the American Academy of Pediatrics, issued a policy statement supporting the fluoridation of public water supplies (PWSs) as a public health benefit. The American Dental Association in January 2025 issued a letter challenging the ruling, saying it was a result of insufficient study and sets a dangerous precedent under TSCA. The USEPA announced on January 17, 2025 that they would challenge the ruling. The USEPA announced on April 7, 2025 that they are expeditiously reviewing scientific information on potential health risks of fluoride in drinking water.
2025 CEC Progress Update
07/22/2025
35 Bahr et al. (2022) looked at vanadium removal from drinking water by fixed-bed adsorption on granular ferric hydroxide. There are no U.S. drinking water standards for vanadium. It is of natural origin. A treatment technology effective for arsenic, granular ferric hydroxide, has been shown to be effective for vanadium. The paper described an extended efficiency test (EET) in Germany that showed removal of vanadium from 28 µg/L down to non-detect (<2 µg/L).
Vanadium appeared on UCMR3, and occurrence data were collected at a MRL of 0.2 µg/L and a health reference level (HRL) of 21 µg/L. With respect to occurrence, 70,000 samples exceeded the MRL and 3.3% of samples from PWSs exceeded the HRL. The WHO guidelines do not contain a limit for vanadium and vanadium is not regulated in the United States. OEHHA proposed a NL of 15 µg/L for vanadium in 2000.
Given similarity to arsenic, potential treatment processes for vanadium removal include coagulation with ferric salts, adsorption on granular ferric hydroxides and other metal-oxide adsorbents, ion exchange (IX) resins, and membrane processes (NF and RO). Previous studies show greater removal of vanadium by granular ferric hydroxide than by other media tested.
Removal with a proprietary granular ferric hydroxide media ran for 3-4 months below the MRL and exceeded German guidance level of 4 µg/L between 140 and 175 days (corresponding to about 30,000 Bed Volumes), at which point the spent granular ferric hydroxide needed to be replaced with fresh material. It should be noted that the lead author of the report works for the company that makes the proprietary granular ferric hydroxide media, and this company paid for the EET to receive regulatory approval in Germany.
Strontium has a USEPA HA level of 4,000 µg/L. Lytle et al. (2023) looked at strontium removal by IX and lime softening. USEPA listed strontium on CCL3 and UCMR3, with data gathered from 2013-2015. USEPA’s preliminary regulatory determination on strontium lowered the health reference level from 4.0 mg/L to 1.5 mg/L. USEPA delayed issuing a final regulatory determination to gather more information including treatment research and economic impact on small and rural communities. The health risk from strontium relates to similarities to calcium that can lead to decreased bone density. Data collected from 4922 public water systems under UCMR3 showed detection of strontium (>0.3 mg/L) in all reporting PWSs with 5.8% greater than 1.5 mg/L in the finished water. With chemical similarities to calcium and magnesium, it has been shown that treatment that removes calcium and magnesium will also remove strontium. IX and precipitative softening are the most common treatment technologies. IX has been found to remove strontium in industrial applications, but to date, removal of strontium in drinking water plants has not been reported. Studies have reported removal of strontium by precipitative softening including 85% removal in plants that employ softening in their treatment train.
Removal with lime plus soda ash achieved 70% removal. Eight treatment plants in Ohio were evaluated, utilizing existing IX and lime softening plants. Calcium was more prevalent than magnesium at all plants.

8.7 Organics
Due to industry, agriculture, and other environmental discharges, residual amounts of organic chemicals can be found in drinking water sources throughout the United States and worldwide.
Rosenblum et al. (2024) performed risk-ranking of regulated and unregulated chemicals in the United States by their environmental concentrations and occurrence, and their respective health reference levels. Many of these are captured in the USEPA’s CCL and UCMR processes but it is noteworthy that 15 of the top 50 risk-ranked chemicals were non-regulated. SFPUC does extensive monitoring of regulated and non-regulated organic chemicals with very few detections due to our high-quality source waters (see above in Section 6.7).
Since the completion of the 2022 CECs in SFPUC Drinking Water, several publications bring to light issues with the treatability of certain organic chemicals and newly identified sources. There is much concern in the water industry regarding the treatability of PFAS as there is a high level of occurrence of PFAS and their chemical characteristics make them difficult to remove in conventional water treatment processes (See PFAS Section) (Nguyen and LeTran, 2024, Cochran et al., 2022). In addition, studies on water treatment systems impacted by wildfires indicate that distribution systems containing Polyvinyl chloride (PVC), High-Density 2025 CEC Progress Update

37 Polyethylene (HDPE) and cross-linked polyethylene can be thermally damaged and release numerous volatile and semi-volatile organic compounds (Isaacson et al, 2025).
Non-regulated organic DBPs continue to be a concern to the water industry. THMs and HAAs are regulated and routinely monitored but minute amount of unregulated organic DBPs (e.g. unregulated nitrosamines, haloacetonitriles, etc.) may impart greater toxicity to drinking water than regulated DBPs (Cochran et al., 2022, Li and Mitch, 2018). (See sections on DBPs).
It is worth noting that in 2025 the USEPA made some decisions on CCL5 organic chemical contaminants. After collecting data, the USEPA has made preliminary determinations to not regulate the following seven organic chemicals: 2-aminotoluene, cylindrospermopsin, ethoprop, permethrin, profenofos, tebuconazole, and tribufos. No determination was made in the 2025 preliminary determination notice for quinoline. 1,4-Dioxane and 1,2,3-Trichloropropane are under federal regulatory evaluation (Cotruvo, 2022).

8.8 PCPPs / EDCs / Hormones
Studies continue to be published that indicate that PPCPs, EDCs, and natural and synthetic hormones are in the environment due to their extensive use and incomplete treatment in WWTPs. In the United States, PPCPs, EDCs, and hormones can be found in drinking source waters that are impacted by domestic and industrial wastewater discharges.
As analytical chemical advances become more available to more researchers, non-regulated organic chemicals are found increasingly in wastewaters and in the environment. In recent years, tracking pharmaceuticals in wastewater has been used as an epidemiology tool to determine stressed communities due to opioid and other pharmaceutical misuse (Dassuncao, WRF, 2022).
In India and Korea, these wastewater-derived contaminants have been found in numerous drinking source waters as well as finished water due to shortening of the water cycle due to increased wastewater discharge and the lack of ability to protect drinking source watersheds (Muambo et al., 2024, Yuniarto and Hadibarata, 2024). Zhang et al. (2024) measured the fate and transport of antibiotics through two unnamed water treatment plants.
Oxidative water treatment processes have been shown effective and reducing or eliminating PPCP, EDC and hormone contamination in drinking source waters. The key to minimizing wastewater derived contamination of drinking water is the protection of source water reservoirs and watersheds from the introduction of wastewater, and robust water treatment in locations where source waters impacted by wastewater are the only alternative.

39 8.9 Microplastics
Microplastics are a low priority CEC for SFPUC. Based on the 2022 CEC Progress Update, the nature of SFPUC source waters coming from protected watersheds makes it unlikely for high levels of microplastics to occur, and concentrations of microplastics in drinking water are likely to be low. SFPUC will participate in the SWRCB program to monitor microplastics.
Microplastics sampling methods are not well-developed. The Policy Handbook (SWRCB, 2022) was developed based on a method study that evaluated multiple methods and selected two methods for use for sampling prescribed in the handbook: infrared spectroscopy and Raman spectroscopy. The Policy Handbook calls for two phases of sampling, each two years, with a 6- month period in between for SWRCB to evaluate Phase 1 results and use them to design Phase 2.
Phase 1 is for drinking water sources and Phase 2 is for treated drinking water. There are no results available at present.
There are several WRF projects currently researching microplastics. Sturm et al. (2022) in Project #4936 looked at fate and removal mechanisms of microplastics through municipal wastewater treatment including liquid discharge, biosolids land application, and biofilm formation in receiving waters. Eight facilities participated and followed standard sampling guidance. Primary clarifiers removed most of the microplastics and wastewater recovery facilities removed 96% of microplastic in the influent. Biosolids concentrations were four or five times higher than the influent. Alspach et al. (2024a) are looking at the fate of microplastics in drinking water treatment plants. The project team designed and tested a sampling apparatus and provided guidance for 16 utility partners to order the parts, assemble the apparatus, collect samples, and perform QA/QC. The goal of the project, WRF #5185, is to empower water treatment plant operations staff for sample collection. Fahrenfeld (2022) in WRF #5088 looked at occurrence, monitoring, and management strategies in treated waters and wastewaters for exposures of microplastics and microplastic fibers. The work showed that stormwater in the 63- 250 µm size class were significantly higher than the 250-500 and 500-2000 µm size classes. The 63-250 µm size class also had greater polymer diversity. Alspach et al. (2024b) in WRF #5155 looked at messaging associated with microplastics in drinking water supplies. They conducted a survey of the public and found tap water quality was not of concern. When microplastics were known to consumers, they considered it a concern but only 39% were aware while 76% of this group rated it at least some degree of concern. The lack of standard methods for microplastics has complicated the ability to compare different data sets. The State of California looked toward method standardization when it implemented two analytical methods to be used: infrared spectroscopy and Ramen spectroscopy. Studies of treatment plant removal of microplastics vary widely from 40-89%. Membrane processes decrease variability but can shed microplastic particulates into treated water. Airborne deposition of microplastics through the treatment train is also possible. The report showed that utility understanding of microplastics may not align with consumer knowledge, while reporting in the media may artificially inflate the perception of toxicity of microplastics. The report also showed that consumers trust their personal physician far more than other sources of information on microplastics. The report provided several microplastics messaging strategies.
Nirmala et al. (2023) provided a critical review on microplastics research in drinking water.
Research on drinking water samples from 14 countries showed 81% of samples had 2025 CEC Progress Update

40 microplastics present and it was shown that it was 98% fibers. Researchers showed conventional treatment (coagulation/flocculation, sedimentation, and filtering) removed 59-71% and GAC treatment removed 19-22%.
Haleem et al. (2024) provided a review of the occurrence and human health implications of microplastics in drinking water. Microplastics are ideal environment to form biofilms. This review focuses on microplastics and their associated chemicals in drinking water, with a specific emphasis on the leeching of additives, oligomers and monomers under distinct environmental conditions during treatment processes. Microplastics can re-enter drinking water through indirect routes like groundwater recharge. The interaction between contaminants and microplastics is not well understood. This includes antibiotics, beta blockers, and PFAS, which primarily undergo hydrophobic interactions during partitioning onto microplastics. However, PPCPs that are characterized by hydrophilic and polar groups have different interactions like pore filling, electrostatic, hydrogen, and other bonds. Microplastics can leach EDCs, contributing to health disorders like diabetes, obesity, and damage to the reproductive system. They also pose risks to the cardiovascular and nervous systems.

8.10 Engineered Nanomaterials and Nanoparticles
Engineered nanomaterials (ENM) and nanoparticles (ENP) are a low priority CEC for SFPUC.
The occurrence and toxicity of incidental nanoparticles, rather than ENPs, should therefore be the focus of future research (Westerhoff, 2018). Because SFPUC source waters come from protected watersheds, occurrence of this CEC is unlikely, with concentrations in drinking water likely to be extremely low, if even detectable. There were no recommendations in the 2022 report. There were no AWWA articles, WRF project reports, or USEPA/SWRCB/OEHHA updates since 2022. Three journal articles were considered in this evaluation of emerging issues.
There are many unknowns associated with ENM and ENP, as described below.
Hofman-Caris et al. (2022) focused on the removal of nanoparticles in drinking water treatment.
No treatment studied could remove all NPs, neither metallic nor plastic. This evaluation of treatment showed coagulation/flocculation/sedimentation (CFS) and rapid sand filtration (RSF) over GAC removed the majority of nanoparticles. Negatively charged natural organic matter (NOM) had a negative effect on inorganic NP removal. The presence of cations, Ca2+ and Mg2+, were critical to good removal. Larger NP (200 nanometers [nm]) were more effectively removed by CFS while smaller NP were more effectively removed by GAC filtration. The review paper showed wastewater treatment removed 90% of NP, but the 10% remaining is still a large amount. Membrane filtration (microfiltration (MF), nanofiltration (NF), and ultrafiltration (UF)) is effective to remove NP. Nanoplastics are likely the most hazardous due to their small size. The presence of biomass had a positive effect on NP removal for sand filters, but the opposite effect was seen for GAC filtration. The removal efficiency was higher for GAC filtration than for sand filtration for the 50 nm nanoplastics. Virgin GAC was better than pre-loaded GAC as would be expected. The removal efficiency values for nanoplastics with GAC were about ten times lower than for inorganic NPs.
Yu et al. (2022) looked at occurrence and removal of engineered nanoparticles in drinking water and wastewater. Engineered nanoparticles (ENPs) are widely used in cosmetics, coatings pigments, personal care products, food packaging, and nanotechnology. Silver (Ag) ENPs have been evaluated for a lengthy period and are used for antifungal, antiviral, and antimicrobial properties. ENPs may bioaccumulate in the body – notably brain, lungs, and/or liver. There are many unknowns regarding ENPs, including the effect of metal oxides. ENP treatment 2025 CEC Progress Update
07/22/2025
42 technologies have been studied, including coagulation/flocculation/sedimentation, membrane filtration, adsorption, and oxidation. Greater than ninety percent removal of ENPs was achieved with flocculation/sedimentation using Fe(OH)3 followed by dissolved air flotation (DAF). Ag- NPs and carbon nanotubes (CNTs) are the most commonly used ENPs due to antibacterial properties and usefulness in medical devices. There are naturally occurring ENPs and NPs due to intentional/unintentional human activities. ENPs are found in urban runoff and in sewage.
Removal exceeded 90% in both hydrophobic and hydrophilic solutions for coagulation, flocculation, and precipitation for TiO2-NP. It has been shown that polyvinylidene fluoride microporous membranes can capture NPs from water in a low cost and environmentally stable manner. It was shown GAC could removal NPs from water. Iron oxide magnetic particle adsorbents retained removal efficiency through four adsorption cycles. Sodium hypochlorite was shown to be effective in removing CNTs but there are many unknowns regarding mechanisms and effect of impurities. Many mechanisms are involved in removing ENPs from wastewater. It has been shown > 90% of ENPs derived from sewage are removed in activated sludge plants.
Overestimation of NP concentration can occur with Inductively Coupled Plasma (ICP) analysis.
There are many unknowns about the risk of using nanomaterials.
Singh, Thakur, and Kumar (2024) presented a review paper covering NP sources and contamination in drinking water; health concerns; mitigation strategies; regulatory frameworks; and future perspectives. Different NPs were considered including titanium dioxide, silver, nanoplastics, nanoscale liquid crystal monomers, copper oxide, and others. These pose risk to human health via ingestion, inhalation, dermal exposure, impact on organs possibly leading to oxidative stress, inflammation, damage to DNA, cytotoxicity, disruption of intracellular energetic mechanisms, reactive oxygen species generation, respiratory and immune toxicity, and genotoxicity. Mitigation and treatment strategies include filtration systems (RO, UF, NF); adsorption processes; coagulation/flocculation; electrocoagulation; advanced oxidation processes; membrane distillation; and ultraviolet (UV) treatment. They all demonstrate high removal of NPs from drinking water.
Nanoparticles are defined as solid colloidal particles within the 10 to 1000 nm size range. In biomedical, NPs are categorized as follows. Metallic NPs include gold and silver. Bimetallic or alloy NPs include iron-cobalt and iron-platinum. Metal oxide NPs include titanium dioxide, cerium dioxide, silica, and zinc oxide. Magnetic NPs include iron oxide NPs. Nanoparticles come from various sources including wastewater effluents, industrial processes, and natural processes like atmospheric deposition. Research on human exposure to NPs is still emerging.
Carbon nanotubes were the first NP studied with respect to human health starting in the early 2000s. NPs can enter the body through inhalation, ingestion, and skin contact. Certain regions may be at greater risk for nanoparticles than others. Specialized analytical techniques are needed, and the following have been considered but are not well understood with respect to NP analysis:
X-ray Diffraction (XRD); scanning electron microscopy (SEM); transmission electron microscopy (TEM); ultraviolet-visible spectroscopy (UV-vis); Fourier transform infrared spectroscopy (FTIR); and Raman spectroscopy. Technologies shown to be effective to remove NPs include UF and NF; adsorption processes (e.g. GAC); Coagulation/flocculation sedimentation/filtration; lime softening and alum addition; electrocoagulation; Advanced Oxidation Processes (AOPs) and UV treatment. There are issues with waste streams with membrane processes and coagulation/flocculation sludge and regeneration requirements for 2025 CEC Progress Update

8.12 DPR Regulations
On October 1, 2024, the California Office of Administrative Law approved Direct Potable Reuse (DPR) regulations. These regulations were finalized after years of research and revision by DDW in accordance with expert panels and industry feedback.
DPR is a major development that expands the scope and influence of water reuse, which is considered to be a significant aspect to California’s future water portfolio. The DPR process produces drinking water from municipal wastewater. Because of this, it will be critical for SFPUC to evaluate the impacts of wastewater contaminants in downstream drinking water sources in our future CEC reports. To do this, SFPUC may investigate chemical sources, communicate with wastewater dischargers, or maintain an inventory of new or significant chemicals that may be discharged into the wastewater collection system. By being proactive and monitoring constituents in the wastewater sources, SFPUC will be cognizant of potential disruptions to our drinking water systems before they occur.
9.0 Plan for CEC Monitoring for the Next Three Years (2025-2027) From 2025 to 2027, SFPUC plans on the following CEC monitoring:
• Microbial – Continue TCR monitoring in SFRWS and continue Legionella monitoring in SFWS.
• PFAS – Conduct repeat groundwater monitoring of the 29 PFAS listed on CCL5 for the 2028 CEC report. Ask SWRCB if PFAS can be sampled at groundwater sources instead of at point-of-entry. If SWRCB grants the request, sample for PFAS at groundwater sources. The SFPUC does not perform PFAS sampling at surface water sources based on protected watersheds and past non-detect results.

44 • Nitrosamines – Conduct voluntary nitrosamines monitoring, which will help establish a baseline prior to indirect potable reuse. Monitor for the six nitrosamines on CCL5 (NDEA, NDMA, NDBA, NDPA, NDPhA, NPYR), plus NMOR and NMEA. • Bromide – Conduct bromide monitoring in source waters as a DBP precursor to bromate and brominated DBPs.
• Chlorate – Conduct chlorate monitoring in drinking water to evaluate impacts of chlorination.
• Iodide – Conduct iodide monitoring as a DBP precursor to iodinated DBPs. • TON – Conduct TON monitoring as a DBP precursor.
• Algal Toxins & HABs – Conduct cyanotoxin monitoring (anatoxin-a, cylindrospermopsin, microcystins, and saxitoxin) in protected watersheds. If algal bloom is detected in a source water, increase monitoring and implement treatment and optimization techniques.
• PPCPs/EDCs/Hormones – Conduct groundwater monitoring prior to 2028, but only if groundwater wells are operated at design production rates. • Microplastics – Implement microplastics monitoring as part of SWRCB mandatory compliance program. Anticipated to start in 2026 once SWRCB’s sampling protocol is finalized.
• Other: Participate in WRF studies, national monitoring surveys, or state monitoring surveys, if identified, for microbial CECs (e.g., Legionella), unregulated DBPs, inorganics, organics, engineered nanomaterials, or any other relevant group of CECs.
In addition to the above monitoring, the SFPUC will continue monitoring cyanotoxins in source water (Upper and Lower Crystal Springs Reservoir, San Andreas Reservoir, Pilarcitos Reservoir, and HTWTP influent), per the frequency stated in the Peninsula Watershed Sanitary Survey. 2025 CEC Progress Update

In the SFRWS, there were only ten
TC positives out of 6,015 samples
collected (0.17%), and in the
SFWS, there were only five TC

Appendix D
Summary of CECs Monitored in SFPUC Drinking Water, 2022 to 2024, with Detects This Appendix summarizes detections in the 10 CEC categories from 2022-24. Detections are not indicative of a risk to public health. These CECs are measured at extremely low levels and no regulatory MCLs exist for them at present. SFPUC takes a proactive approach to monitoring CECs well before they are known to be a concern to health.
