For Water Subcommittee Meeting May 29, 2025
TO: Honorable Water Subcommittee Members
APPROVAL: John Rossi, Interim Utilities Director
FROM: Nicole Hemmans, Senior Administrative Analyst
Request for Feedback Regarding Setting a Public Hearing for the 2025 Public Health Goals Report and Provide Comments on the 2024 Consumer Confidence Report on Drinking Water.

RECOMMENDATION
Staff requests that the Water Subcommittee provide feedback on the 2025 PHGs and 2024 CCR before seeking City Council approval to schedule a Public Hearing at the meeting on July 22, 2025. A formal presentation will be made at that time.

BACKGROUND
The City of Rialto is required to provide the public with two distinct types of water quality reports, each serving a different purpose: the Public Health Goals Report and the Consumer Confidence Report.

Public Health Goals Report (PHGs): Provisions of the California Health and Safety Code specify that larger water utilities with more than 10,000 service connections prepare a PHG Report and conduct a Public Hearing by July 1, 2025, if any water quality results from 2022-2024 exceed non-enforceable PHG levels set by the California Office of Environmental Health Hazard Assessment. PHGs are health-based goals, not regulatory limits. A public hearing must be held to present the report and receive public input. Staff is requesting feedback on setting the Public Hearing for the June 24, 2025, City Council meeting.

Consumer Confidence Report (CCR): The CCR is an annual report required under federal and state regulations. It is designed to inform customers about the quality of their drinking water, including compliance with enforceable drinking water standards. The CCR for calendar year 2024 confirms that the City of Rialto’swater meets or exceeds all applicable state and federal standards. This report is publicly available online and in hard copy at City Hall, the City Clerk’sOffice, and the Rialto Water Services Customer Service office. Staff is requesting comments from the Water Subcommittee before going to City Council.

Together, these reports provide transparency regarding water quality, with the PHG report addressing theoretical health risk benchmarks and the CCR documenting regulatory compliance.

ANALYSIS/DISCUSSION
Public Health Goals Report (PHGs):

The California Office of Environmental Health Hazard Assessment (OEHHA) sets Public Health Goals (PHGs) based solely on public health risk considerations. Of the 125 constituents tested, the City of Rialto's water supply meets all the PHGs and Maximum Contaminant Level Goals (MCLGs) standards except for three.

The attached 2025 PHGs report information is required by law because three constituents detected are above the Public Health guidelines: Arsenic, Hexavalent Chromium, and 2,3,7,8- Thtrachlorodibenzo-p-dioxin (TCDD).

1. Arsenic is a semi-metal element in the periodic table. The PHG for arsenic is 0.004 ppb and the MCL is 10 ppb. Arsenic was found to occur in one groundwater well, City Well 2, with a detection range of 5.1 ppb to 9.7 ppb.

2. Hexavalent Chromium (Cr (VI)) can come from both natural and industrial sources. The PHG for Hexavalent Chromium is 0.02 ppb and the MCL is 10 ppb. Hexavalent Chromium was found to occur in all groundwater wells and import water sources with a range of 0.16 ppb to

2.8 ppb.

3. 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a highly toxic and persistent environmental pollutant. The PHG for TCDD is 0.05 picogram/liter and the MCL is 30 picogram/liter. TCDD was found to occur in Chino 2, City Well 2, EW-1, Miro 3, and the Baseline Feeder, with a detection ranging between 1.17 picogram/liter and 4.92 picogram/liter.

Although the City exceeded the PHG on three constituents, all three were well within the drinking water standards and the Maximum Contaminant Levels (MCLs). It should be noted that testing for Hexavalent Chromium and 2,3,7,8-Tetrachlorodibenzo-p-dioxin were not sampled in the previous Public Health Goals report, per regulatory requirements.

10 File #: WS-25-0371, Version: 1, Agenda #:

The Public Health Goals Report will provide detailed information, including:
· The category or type of health risk that could be associated with each constituent. · The best available technology (BATs) could be used to reduce the level of the constituent. · An estimate of the cost of installing treatment if it is appropriate and feasible.

The 2025 edition of the Public Health Goals Report is included as Attachment 1.

Consumer Confidence Report (CCR):

All of the water quality data collected by our water system for 2024 is summarized in the City of Rialto 2024 Consumer Confidence Reports which states that the City has either met or exceeded the standards set by the State and Federal Law.

The 2024 CCR for the City of Rialto provides information about:
· The source of drinking water.
· A brief summary of the risks of contamination of the local drinking water source. · The regulated contaminants found in local drinking water. · The potential health effects of any contaminant detected in violation of an EPA health standard.

Additional information is included in the 2024 edition of the Consumer Confidence Report, included as Attachment 2.

FINANCIAL IMPACT
Operating Budget Impact
The financial impact associated with the CCR is minimal, as the primary method of distribution is the website.

Capital Improvement Budget Impact
There will not be any impact to the Capital Improvement Budget from the proposed action.

CITY OF RIALTO

REPORT ON WATER QUALITY

RELATIVE TO PUBLIC HEALTH GOALS
FOR YEARS 2022, 2023, 2024

BACKGROUND:

Provisions of the California Health and Safety Code (Section 116470 (b))1 specify that larger water utilities (>10,000 service connections) prepare a special report by July 1, 2025 if their water quality measurements have exceeded any Public Health Goals (PHGs). PHGs are non - enforceable goals established by the Cal- EPA’s Office of Environmental Health Hazard Assessment (OEHHA). The law also requires that where OEHHA has not adopted a PHG for a constituent, the water suppliers are to use the Maximum Contaminant Level Goals (MCLGs) adopted by United States Environmental Protect ion Agency (USEPA).

Only constituents which have a California primary drinking water standard and for which either a PHG or MCLG has been set, are to be addressed. This report covers the “detection” of contaminants above both PHGs and MCLGs found in the City’s water system during calendar years 2022, 2023 and 2024.

There are a few constituents that are routinely detected in water systems at levels usually well below the drinking water standards for which no PHG nor has MCLG yet been adopted by OEHHA or USEPA including Total Trihalomethanes. These will be addressed in a future required report after a PHG has been adopted.

If a constituent was detected in the City’s water supply between 2022 and 2024 at a level exceeding an applicable PHG or MCLG, this report provides the information required by law. Included is the numerical public health risk associated with the MCL and th e PHG or MCLG, the category or type of risk to health 12 that could be associated with each constituent, the best treatment technology available that could be used to reduce the constituent level, and an estimate of the cost to install that treatment if it is appropriate and feasible.

WHAT ARE PHG’S:

PHGs are set by the California Office of Environmental Health Hazard Assessment (OEHHA) which is part of Cal- EPA and are based solely on public health risk considerations. None of the practical risk - management factors that are considered by the USEPA or th e California Division of Drinking Water in setting drinking water standards (MCLs) are considered in setting the PHGs. These factors include analytical detection capability, treatment technology available, benefits and costs. The PHGs are not enforceable and are not required to be met by any public water system. MCLGs are the federal equivalent to PHGs.

WATER QUALITY DATA CONSIDERED:

All of the water quality data collected by our water system between 2022 and 2024 for purposes of determining compliance with drinking water standards was considered. This data was all summarized in our 2022, 2023, and 2024 Consumer Confidence Reports and was made available online at www.rialtoca.gov.

GUIDELINES FOLLOWED:

The Association of California Water Agencies (ACWA) formed a workgroup which prepared guidelines for water utilities to use in preparing these newly required reports. The ACWA guidelines were used in the preparation of our report. No guidance was available from state regulatory agencies.

BEST AVAILABLE TREATMENT TECHNOLOGY AND COST ESTIMATES:

Both the USEPA and DDW adopt what are known as BATs or Best Available Technologies which are the best known methods of reducing contaminant levels to the MCL. Costs can be estimated for such technologies. However, since many PHGs and all MCLGs are set much lower than the MCL, it is not always possible nor feasible to determine what treatment is needed to further reduce a constituent downward to or near the PHG or MCLG, many of which are set at zero. Estimating the costs to reduce a constituent to zero is difficult, if not impossible because it is not possible to verify by analytical means that the level has been lowered to zero. In some cases, installing treatment to try and further reduce very low levels of one constituent may have adverse effects on other aspects of water quality.

CONSTITUENTS DETECTED THAT EXCEED A PHG OR A MCLG:

With three exceptions, the City of Rialto's water supply complies with the Public Health Goal (PHG) and Maximum Contaminant Level Goal (MCLG) standards. This report details the constituents identified in the drinking water sources that exceeded the PHG, or in the absence of a PHG, the MCLG. 13 ARSENIC:

Arsenic is a semi-metal element in the periodic table. The PHG for arsenic is 0.004 ppb (parts per billion).

Effective January 23, 2006, the MCL for arsenic was lowered from 50 ppb to the revised standard of 10 ppb. The City of Rialto is required to sampleS on a quarterly basis.

When a system is sampling for arsenic annually or less frequently at any sampling point and has a monitoring result that exceeds the MCL, the system must increase the frequency of monitoring at that sampling point to quarterly sampling. Since the initial detection of arsenic on March 22, 2023 during the routine triennial sampling, the City has been on a quarterly sampling plan for arsenic at City Well 2.

Arsenic test results for the City for the years 2023 and 2024 from all groundwater and import sources had a range of not detected to 9.7 ppb. Arsenic was found to occur in one groundwater well (City Well 2). It should be noted that City Well 2 water is blended with additional water sources that contain no detectable levels of arsenic. The following well had detection levels above the PHG of 0.004 ppb:

Arsenic is a naturally occurring element that is found in combination with either inorganic or organic substances to form many different compounds. Inorganic arsenic compounds are found in soils, sediments and groundwater. These compounds occur naturally or as a result of mining, ore smelting, and industrial use of arsenic. Organic arsenic compounds are found mainly in fish and shellfish. In the past, inorganic forms of arsenic were used in pesticides and paint pigment. They were also used as wood preservatives and as a treatment for a variety of ailments. Today, usage of arsenic–containing pesticides and wood preservatives is restricted.

People are most likely to be exposed to inorganic arsenic through drinking water and, to a lesser extent, through various foods. Unusually large doses of inorganic arsenic can cause symptoms ranging from nausea, vomiting, and diarrhea to dehydration and shock. Long-term exposure to high levels of inorganic arsenic in drinking water has been associated with skin disorders and increased risks for diabetes, high blood pressure, and several types of cancer. Inorganic arsenic and arsenic compounds are considered to be cancer-causing chemicals. Forms of organic arsenic found in seafood are not known to be toxic to humans.

Arsenic has no smell, taste, or color when dissolved in water, even in high concentrations, and therefore only laboratory analysis can determine the presence and concentration of arsenic in water. It occurs naturally in rocks, mineral deposits, and soil, water, air, and plants and animals. It can be further released 14 into the environment through natural activities such as volcanic action, erosion of rocks and forest fires, or through human actions.

Because it occurs naturally in the environment and as a by -product of some agricultural and industrial activities, it can enter drinking water through the ground or as runoff into surface water sources.

The City water system is in full compliance with federal and state rules for arsenic.

The BATs for arsenic to lower the level below the MCL are activated alumina, coagulation/filtration, ion exchange, lime softening, electro-dialysis, RO, and oxidation/filtration. Although the City of Rialto arsenic levels are below the MCL, RO would be req uired to lower the arsenic level additionally below the PHG.

Although cost estimates for large- scale treatment installations are difficult, estimated costs for RO include annualized capital, construction, engineering, planning, environmental, contingency, operations and maintenance, and are based on the ACWA Public Health Goals Survey of Cost Estimates for Treatment Technologies (2012). The updated (2021) cost estimate for RO for the City of Rialto’s well using this data is estimated to be $35 million. This would result in an average estimated cost of $2,200 per customer per year. This includes additional costs for corrosion control because water treated by RO is corrosive and could cause the water to exceed lead and copper regulations. The City does not int end to install BATs for arsenic at this time.

HEXAVALENT CHROMIUM:

Hexavalent chromium (Cr(VI) can come from both natural and industrial sources. Natural sources include rocks and minerals. Weathering processes can release chromium from these minerals into soil and groundwater. Industrial sources include processes like electroplating, stainless steel production, and the use of chromium in various industrial applications like pigments, dyes, and coatings.

People are most likely to be exposed to hexavalent chromium through breathing in fumes, mists, or dusts, ingesting it in food or water, or through direct skin contact. Major sources of exposure include welding, metal finishing, and the use of chromate pigments in various industries. Hexavalent chromium is a known human carcinogen, particularly when inhaled, and poses various health risks, including lung cancer, skin irritation, and reproductive harm. Exposure to Cr(VI) can also cause irritation of the nose, throat, and lungs. It is important to note that while trivalent chromium is an essential nutrient, hexavalent chromium is a less common form that is often man -made and associated with industrial sources.

Hexavalent chromium is odorless and tasteless when dissolved in water, making it difficult to detect even in high concentrations, and therefore only laboratory analysis can determine the presence and concentration of hexavalent chromium in water.

Because it occurs naturally in the environment and as a by -product of some industrial activities, it can enter drinking water through the ground or as runoff into surface water sources. 15 The City water system is in full compliance with federal and state rules for hexavalent chromium.

Hexavalent chromium was found to occur in all groundwater wells and import water. Cr(VI) test results for the City for the year 2024 from all groundwater and import sources had a range of 0.16 ppb to 2.8 ppb.

The Best Available Technology (BATs) to lower hexavalent chromium are coagulation/filtration, ion exchange, and Reverse Osmosis (RO). These BATs would be required to lower hexavalent chromium levels below the PHG. Estimated costs for RO include annualized capital, construction, engineering, planning, environmental, contingency, operations and maintenance, and are based on the ACWA Public Health Goals Survey of Cost Estimates for Treatment Technologies (2012). The updated (2021) cost estimate for RO for the City’s wells and surface water treatment plant using this data is estimated to be $35 million. This would result in an average estimated cost of $2,200 per customer per year. Since the City’s hexavalent chromium levels are below the former MCL, the City does not intend to install BATs for hexavalent chromium at this time.
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD):
2,3,7,8-TCDD, often shortened to “dioxin”, is a highly toxic and persistent environmental pollutant. It’s a colorless solid with no odor, and it’s usually formed as a byproduct of burning processes or organic synthesis. TCDD is known for its toxic and carcinogenic effects on animals, and it is considered a probable human carcinogen.

People are most likely to be exposed to TCDD through various industrial processes like herbicide and insecticide manufacturing, waste incineration, and metal processing. TCDD can accumulate in the food chain, particularly in animal fat, so exposure can occur through consuming meat, milk, eggs and fish. In some cases, TCDD can be released into the environment through industrial accidents or spills, potentially contaminating soil and water. The US Environmental Protection Agency and National Institutes of Health (NIH) classify TCDD as a human carcinogen, with studies suggesting an increased risk of certain cancers, including lymphomas and lung cancer. Acute exposure to TCDD can cause liver enzyme alterations and potential liver damage. Chronic exposure can lead to alterations in immune function and may increase the risk of cardiovascular disease. Exposure can cause mild neuropathies and potentially affect the 16 developing nervous system. TCDD can cross the placental barrier and affect fetal development, potentially leading to developmental toxicity. Long term exposure can impact the endocrine system.

There are methods for removing dioxin from water, including filtration through granulated sorbents and ozonization. It was found that the method of filtration through granulated sorbents was most effective at removing dioxins from water: 90 -95% of all PCDD and PCDF isomers were removed from water samples. This research also shows that the most toxic congener, 2,3,7,8 -TCDD, can be removed effectively and efficiently. An engineering study needs to be performed to determine the cost of removal.

The City water system is in full compliance with federal and state rules for 2,3,7,8-TCDD.

RECOMMENDATIONS FOR FURTHER ACTION:

The drinking water provided to the City of Rialto's residents meets all state and federal drinking water standards established by the State of California, the Division of Drinking Water (DDW), and the U.S.

Environmental Protection Agency (USEPA). These standards are stringently set to protect public health and ensure the safety of the water supply.

While the water quality already meets these rigorous standards, certain constituents have been identified in the water at levels significantly below the Maximum Contaminant Levels (MCLs). MCLs are health-based limits established to define "safe drinking water" and ensure that no adverse health effects occur due to long-term exposure.

Although the levels of these identified constituents are well below the MCLs, it is technically possible to further reduce them through additional and costly treatment processes. However, the effectiveness of these processes in achieving significant reduct ions at such low levels is uncertain. Moreover, the potential health benefits of these further reductions are unclear and may not be quantifiable, as the current levels already pose minimal risk to public health.

Given the substantial costs associated with additional treatment, the uncertainty of its effectiveness, and the lack of clear and quantifiable health benefits at these already low levels, no further action to reduce the levels of these constituents is proposed at this time. The current water treatment processes are sufficient to ensure the safety and quality of the drinking water for the City of Rialto's residents. 17 REFERENCES:

Request for Feedback Regarding Setting a Public Hearing to Place Sewer Service Charges on the County Property Tax Roll for Delinquent Accounts. (ACTION)

RECOMMENDATION
Staff requests feedback regarding setting a public hearing to place sewer service charges on the County Property Tax Roll for delinquent accounts.

BACKGROUND
The City of Rialto (City) / Rialto Utility Authority (RUA) provides sewer services throughout the entire City and areas of Bloomington. Where RUA provides water service, both water and sewer services are billed together. For delinquent accounts, the RUA can impose penalties and shut off water services to promote payment, per Rialto Municipal Code Section 12.08. However, there are areas of the City where either the West Valley Water District or the Fontana Water Company provides water services and the RUA only bills for sewer service. The sewer-only accounts have high delinquency rates, as the RUA cannot disconnect services for lack of payment.

To collect sewer-only accounts more effectively, the Rialto Municipal Code Section 12.08.201 was amended to allow for placement of delinquent charges on property tax bills through the County Tax Collector’s Office. The Ordinance approved on June 19, 2007, provides a method for collecting delinquent accounts like the lien placement process used for solid waste delinquent accounts.

ANALYSIS/DISCUSSION
During the spring of each year, Staff develops a list of properties to be levied for delinquent sewer fees. Once the list of properties to be levied has been completed, the list will be compared with the most recent County property ownership data. Changes will be incorporated into the final list which is then submitted to the County. This list is comprised of accounts where the account owner is delinquent on sewer payments. Once created, this list is presented to the City Council/Rialto Utility City of Rialto Printed on 5/22/2025Page 1 of 3

Authority Board for permission to place the delinquent sewer fees on the tax rolls.

To meet the County submittal deadline, several things must occur, most notably, a list must be presented to the City Council/Rialto Utility Authority Board of properties meeting the criteria for placement of liens with the County and a public hearing must be held to approve the levy.

Notification letters will be sent to the delinquent account holders and the property owner, if different, alerting them of the RUA’splan to place the delinquent charges on the property tax roll and giving them one last opportunity to pay.

The last date for a customer to pay their delinquent sewer bill before placement on the tax rolls is June 25, 2025. It should be noted that if a customer pays their delinquent wastewater bill prior to the deadline, their property and the levy amount will be removed from the list provided to the county.

Once the list of properties to be levied has been completed, the list will be compared with the most recent County property ownership data. Changes will be incorporated into the final list, which is then submitted to the County.

SCHEDULE/LEVY PROCESS
If the City were to post levies for this fiscal year, the following tasks must be completed by the deadlines listed below:

The total levy amount for Fiscal Year 2024-2025 is estimated to be approximately $1.16M, representing approximately 1,686 delinquent accounts.

VI. WATER QUALITY COMPLAINTS
No complaints were received during this reporting period.

VII. OPERATIONS UPDATE
The overall operational strategy is to meet the daily water demand. The City of Rialto water system has six operational wells, one of which is owned by the County of San Bernardino and operated by Veolia; Oliver P. Roemer Treatment Plant (OPRTP), which is jointly owned by the City (25%) and West Valley Water District (WVWD); purchased water through the Baseline Feeder (BLF) system from San Bernardino Valley Municipal Water District (SBVMWD); and, if required to meet demand, additional water can be supplied by the City of San Bernardino (CSB) through the BLF for emergency supply only with no guarantee of actual delivery. Water produced from City Well 4A discharges into the BLF and its production is included in deliveries from that shared transmission line when City Well 4A is in service.
66 12

The overall pumping strategy is based on adjudicated rights, well availability, remediation requirements, and quality of source, cost to operate, and varying weather conditions. TDS effluent concentrations for the City of Ria lto WWTP are taken into consideration when operating the facilities and water sources.

A. Operational Wells
All wells were operational.

B. Valve Activity
On the basis of information collected in 2019, Veolia now has a baseline assessment of all valves and has initiated a new cycle of valve exercising . 41 valves were exercised for the month of February.

No complaints were received during this reporting period.

VII. OPERATIONS UPDATE
The overall operational strategy is to meet the daily water demand. The City of Rialto water system has six operational wells, one of which is owned by the County of San Bernardino and operated by Veolia; Oliver P. Roemer Treatment Plant (OPRTP), which is jointly owned by the City (25%) and West Valley Water District (WVWD); purchased water through the Baseline Feeder (BLF) system from San Bernardino Valley Municipal Water District (SBVMWD); and, if required to meet demand, additional water can be supplied by the City of San Bernardino (CSB) through the BLF for emergency supply only with no guarantee of actual delivery. Water produced from City Well 4A discharges into the BLF and its production is included in deliveries from that shared transmission line when City Well 4A is in service.
100
15 The overall pumping strategy is based on adjudicated rights, well availability, remediation requirements, and quality of sou rce, cost to operate, and varying weather conditions. TDS effluent concentrations for the City of Rialto WWTP are taken into consideration when operating the facilities and water sources.

A. Operational Wells

Total revenue collected in March 2025 is $ 4,040,000 whereas Non-Rate Revenue is $ 259,000; Utility Revenue is $3,686,000 and Tax / Ambulance Revenue at $95,000.

RWS collects Utility User Taxes and Ambulance Fees on behalf of the City of Rialto. The Utility User Tax (UUT) rates are based on the total billed amount, therefore the collection fluctuates as billed amounts change. The total UUT charges collected in March 2025 and March 2024 are $90,000 and $204,000 respectively. Ambulance Revenue is also collected on behalf of the City of Rialto totaling $5,000 in March 2025 and $5,000 in March 2024.
