4. Water Production and Treatment
During this reporting period, the City of Adelanto produced 52.980 million gallons of water from six active wells. One of these wells (8G2) disinfects water at the wellhead prior to transmission to one of six water storage tanks. Four of these wells (1G, 3G, 4G, 8G) send water to the Water Treatment Plant (WTP) to treat iron and manganese. This treatment process consists of Iron and Manganese Filtration. Following treatment for iron and manganese, the WTP’s effluent is blended with water from the other wells and purchased water from Mojave Water Agency and the City of Victorville (as needed) in the City’s water storage tanks and distribution system. In August, 112.700 million gallons were purchased from MWA R3 connection, and 0 million gallons were purchased from the City of Victorville.

During this reporting period (August), the WTP treated 28.44 million gallons of raw water, and all samples were within acceptable ranges for iron, manganese, and other contaminants. In addition to weekly samples sent to Geo Monitor, Woodard & Curran’s staff takes daily samples to maintain process control, and these results are found in Table 4-1.

6.1 Projects

6.1.1 Lead & Copper Compliance Sampling
Status: Customer outreach and sampling preparation underway.

Lead and Copper Compliance Sampling is a critical regulatory requirement that helps ensure the City of Adelanto continues to provide safe and reliable drinking water while maintaining compliance with federal and state drinking water regulations.

The California State Water Resources Control Board requires community water systems to conduct periodic lead and copper monitoring at representative residential and commercial locations throughout the distribution system. Adelanto's monitoring program requires triennial sampling at 30 approved locations to evaluate the potential impact of plumbing materials on drinking water quality.

During August, Woodard & Curran staff initiated outreach to residents and businesses that have previously participated in the sampling program. Maintaining consistent sampling locations from one monitoring event to the next provides reliable trend data and supports long-term assessment of water quality conditions throughout the system.

Lead and Copper samples must be collected by participating customers from a cold-water tap following a minimum six-hour stagnation period with no water use. Once collected, samples are submitted to a certified laboratory for analysis.

Customer notification and sampling instruction materials were prepared and distributed to participating residents and businesses. Upon receipt of laboratory results, the data will be reviewed, compiled, and submitted to the California State Water Resources Control Board along with the required reporting forms and customer notification documentation.

6.1.2 Water Treatment Plant Filter Media Replacement
Status: Material delivery in progress; installation scheduled for November.

The City is currently under contract to replace the filter media at the Iron and Manganese Water Treatment Plant. Filter media replacement is a critical maintenance activity that helps ensure continued treatment efficiency, regulatory compliance, and high-quality drinking water. Over time, filter media can become fouled with accumulated iron, manganese, and other particulates, reducing its effectiveness and overall treatment performance.

During the reporting period, new filter media began arriving on-site in preparation for the project.

Replacement of the existing media is currently scheduled to commence in mid-November. Upon completion, the new media will enhance filtration performance and support the long-term reliability of the treatment process.

6.1.3 AWWA Water Loss Audits
Status: Validation underway.

The American Water Works Association (AWWA) Water Audit is an essential tool for evaluating the efficiency and performance of the City’s water distribution system. By accounting for all water produced, delivered, and consumed, the audit helps identify water losses associated with leaks, meter inaccuracies, data management issues, and unauthorized consumption.

Annual water audits provide valuable information to support asset management, prioritize infrastructure improvements, reduce non-revenue water, and enhance overall system reliability. The audit process also supports regulatory compliance, promotes responsible water resource management, and assists the City in operating its water system in a cost-effective and sustainable manner.

Validation of the City’s Calendar Year 2023, 2024, and 2025 AWWA Water Audits is currently underway.

Once completed, the validated audits will provide a more accurate assessment of system performance and help guide future water loss control and operational improvement efforts.

6.1.4 Water Meter Automatic Reading Integration
Status: Integration and communication issue resolution ongoing.

The City continues to make progress with the implementation and optimization of its Advanced Metering Infrastructure (AMI) system. Current efforts are focused on system integration, data validation, and performance optimization to ensure reliable communication between field-installed meter communication units and the City’s utility billing platform.

Water Operations and Utility Billing staff are working collaboratively to identify and resolve communication exceptions, verify meter performance, and improve the accuracy of data transferred between the AMI system and billing software. Through this process, approximately 1,000 meters have been identified for further evaluation due to issues such as failed meter registers, obsolete meter components, or communication deficiencies.

As system integration activities continue, the AMI program is expected to provide significant operational and customer service benefits, including improved billing accuracy, enhanced customer support, faster leak detection, reduced manual meter-reading requirements, and increased overall efficiency across the City’s water utility operations.

Over the coming months, the City and Water Operations staff will remain focused on resolving remaining communication issues, optimizing data integration, and maximizing system performance. These efforts will help ensure the long-term success of the AMI program while fully realizing the benefits of the City’s modernized metering infrastructure, including improved asset management, operational efficiency, and customer service.

8. Budget
Budget tracking for Fiscal Year 2026-2027:

Woodard & Curran is currently undergoing a transition to a new Enterprise Resource Planning (ERP) system that will support financial management, project accounting, invoicing, procurement, and reporting functions across the organization. As part of this implementation, financial data and reporting processes are being migrated, validated, and reconciled within the new system environment.

Due to the ongoing ERP transition, updated financial information is not currently available for inclusion in this month's report. Financial records remain under review as system data is reconciled and reporting functionality is finalized. As a result, comprehensive financial reporting, including budget-to-actual comparisons, expenditure summaries, and other financial metrics, cannot be provided at this time.

Operational and project activities continue to be performed in accordance with contract requirements; however, financial information will remain unavailable until the ERP transition and associated reconciliation efforts have been completed. Woodard & Curran's finance and implementation teams continue to work through the remaining transition activities to ensure the accuracy and integrity of financial data before it is released for reporting purposes.

Financial reporting will resume once validated information becomes available through the new ERP system.

The prior period budget tracker is presented below pending full reconciliation through the new ERP system.

The City of Adelanto utilizes SmartCover® monitoring
technology as part of its proactive wastewater collection system management program. Smart Covers are installed on key sewer manholes and critical collection system locations to provide real-time monitoring of wastewater levels and system conditions. These devices continuously transmit data and generate alerts when sewer levels rise above predetermined thresholds, allowing operators to identify potential blockages, inflow and infiltration issues, or developing overflow conditions before they become sanitary sewer overflows (SSOs).

The system enhances operational awareness, supports regulatory compliance, improves emergency response times, and allows collection system staff to prioritize maintenance activities more efficiently.

There were no high-level alarms during the month of July. 589

RE: Notification of Nonconformance – MBAS Analysis
Client Sample ID: Effluent Sample Collected 07/15/2026
Babcock Work Order: C6G1873-02
Dear Mr. Hause,
This letter serves as formal notification of a nonconformance associated with the above-referenced work order.

After the client reported a missing MBAS result, Babcock Laboratories reviewed the Chain of Custody (COC) and associated laboratory records. The review confirmed that MBAS analysis had been requested; however, the analysis was inadvertently omitted during sample login and was not entered into the laboratory information management system. The omission was also not identified during review prior to issuance of the original laboratory report.

As a result, the MBAS analysis was not performed within the required holding time. After Babcock confirmed the omission, the client requested that the sample be analyzed outside the required holding time rather than resampled. The analysis was completed, and the result is included in the amended laboratory report with the appropriate qualification indicating that the holding time requirement was exceeded.

All other requested analyses were completed and reported under the referenced Babcock Laboratories work order.

The quality and reliability of the data we provide are of the utmost importance to Babcock Laboratories. We apologize for this oversight and any inconvenience it may have caused.

If you have any questions or require additional information, please contact your Project Manager in Client Services.

Sincerely,
Julia Sudds
Director of Quality

1. Executive Summary
During August 2026, the City of Adelanto Wastewater Treatment Plant (WWTP) and collection system maintained full regulatory compliance and recorded no sanitary sewer overflows (SSOs). Treatment and collection services remained reliable while staff advanced safety corrections, preventive maintenance, asset management, and system monitoring.

Compliance Wastewater Treated Collection System Safety & Maintenance 100% compliant
0 permit violations
105.245 MG total

3.395 MGD average
0 SSOs
9,005 LF cleaned
15,300 LF inspected

60.5% audit completion
89 PMs completed
Operational Highlights
 All required sampling was completed and the facility maintained 100% regulatory compliance.

Monthly mean effluent results were 6.8 mg/L BOD, 0.17 mg/L MBAS, and 1.7 mg/L Total Nitrogen, each below the applicable monthly mean limit.
 The WWTP treated 105.245 million gallons during August, averaging 3.395 MGD. Peak flow reached 3,570 GPM on August 24.
 The collection system recorded zero SSOs for August and year-to-date. Crews cleaned 9,005 linear feet and completed 15,300 linear feet of CCTV inspection, increasing annual totals to 60,292 feet cleaned and 35,861 feet inspected.
 SmartCover monitoring generated no high-level alarms; however, monitoring indicates the Auburn and Verbena location remained full with limited additional sewer capacity, warranting continued operational attention.

Safety, Reliability, and Asset Management
 The Adelanto team remained compliant with SPARKS requirements and has completed 101 of 167 Startup Safety Audit actions, or 60.5%. August safety training focused on preventing back injuries.  Operations staff restored controls after communication errors affected the aeration blowers, Biolac system, and headworks; repaired the facility backflow device; and continued troubleshooting final-clarifier sludge-depth sensors.
 RAS Pump No. 1 was removed from service following a seal leak, with RAS Pump No. 2 placed in service. Staff also reprogrammed the primary centrifuge VFD after a memory issue erased system programming. Utility Cloud is fully implemented and continues to support maintenance and asset tracking.

Bottom Line
August operations were stable and compliant, with zero SSOs, strong effluent performance, expanded collection-system inspection, and continued progress on safety and asset management.

Adelanto Wastewater MOR 2026-08 August 2026
The City of Adelanto utilizes SmartCover® monitoring
technology as part of its proactive wastewater collection system management program. Smart Covers are installed on key sewer manholes and critical collection system locations to provide real-time monitoring of wastewater levels and system conditions. These devices continuously transmit data and generate alerts when sewer levels rise above predetermined thresholds, allowing operators to identify potential blockages, inflow and infiltration issues, or developing overflow conditions before they become sanitary sewer overflows (SSOs).

The system enhances operational awareness, supports regulatory compliance, improves emergency response times, and allows collection system staff to prioritize maintenance activities more efficiently.

SmartCover monitoring recorded no high-level alarms during August. At Auburn and Verbena, however, the reported maximum d/D reached 100%, indicating that the monitored pipe depth reached the pipe diameter during the reporting period. This condition warrants continued monitoring and technical evaluation.

7. Maintenance & Repair
The City of Adelanto Wastewater Treatment Plant (WWTP) continues to execute a proactive maintenance and asset management program focused on improving system reliability, reducing emergency repairs, and maximizing the useful life of critical infrastructure. The Utility Cloud computerized maintenance management system (CMMS) has now been fully implemented and serves as the centralized platform for managing asset inventories, work orders, inspections, maintenance history, and equipment performance throughout the wastewater treatment plant and collection system.

Consistent with the asset management framework outlined in Woodard & Curran's operations proposal, the program supports preventative, predictive, and corrective maintenance activities while providing the data necessary for condition assessment, risk-based prioritization, lifecycle planning, and future capital improvement planning. Utility Cloud enables staff to systematically track maintenance activities, document asset condition, identify performance trends, and prioritize investments that improve reliability and reduce long-term operational costs.

The fully implemented system will continue to be refined and updated as additional asset information, maintenance procedures, and operational data are incorporated. These ongoing improvements will enhance maintenance planning, support data-driven decision-making, and strengthen the City's ability to effectively manage its wastewater infrastructure while maintaining regulatory compliance and reliable service to the community. Recent maintenance efforts have included routine preventive maintenance, equipment inspections, sewer system cleaning and inspection activities, and corrective repairs necessary to support uninterrupted plant and collection system operations.

Maintenance highlights for the reporting period:
 8/5/26: Communication errors to the aeration blowers, biolac treatment system, and headworks area of the WWTP occurred. Staff was able to reset the communication network and return functionality.
 8/5/26: The backflow prevention device at the facility was repaired.  8/7/26: Sensor lens caps were replaced on the north biolac basin dissolved oxygen sensor.  8/13/26: Troubleshooting of accuracy concerns with the sludge depth sensors in the final clarifiers is ongoing. The manufacturer and original installer are being consulted.  8/19/26: RAS pump #1 failed due to a seal leak. It will be evaluated during scheduled annual service in September. RAS pump #2 is currently in service in place of this pump. The facility has 3 RAS pumps in total with 2 in operation at a time.
 8/31/26: Woodard & Curran Technician visited to reprogram the VFD for the primary Centrysis centrifuge that is used to dewater solids at the facility. The VFD had a memory issue and programming for the system had been lost.

TO: Honorable Chairman, and Public Utility Authority Members FROM: Jessie Flores, Executive Director
BY: Brenda Lopez, City Clerk/Director of Governmental Services SUBJECT: RESOLUTION 26-07 AUTHORIZING PARTICIPATION IN PROPOSED PFAS CLASS

ACTION SETTLEMENTS
STAFF RECOMMENDATION:

Adopt Resolution No. 26-07 authorizing the Adelanto Public Utility Authority (APUA) to participate in the proposed class action settlements with Amerex Corporation, Archroma U.S., Inc., Carrier Global Corporation, and Nation Ford Chemical Company relating to PFAS contamination of public drinking water.

BACKGROUND:

Litigation involving contamination of water and soil by Per- and Polyfluoroalkyl Substances (PFAS) manufactured by various entities was consolidated in the United States District Court for the District of South Carolina as In Re: Aqueous Film-Forming Foams Product Liability Litigation, MDL No. 2:18-mn2873-RMG.

Proposed settlements have been filed involving Amerex Corporation, Archroma U.S., Inc., Carrier Global Corporation, and Nation Ford Chemical Company to compensate eligible public water systems, including APUA.

Approval of the proposed Resolution will authorize APUA to participate in the settlements and authorize completion and execution of the necessary settlement documentation, releases, and agreements.

The Resolution also authorizes outside counsel to continue pursuing APUA's claims against remaining defendants and other applicable claims related to PFAS contamination. 752
FISCAL IMPACT:

There is no expenditure associated with approval of the Resolution. Any settlement proceeds received by APUA will be determined through the settlement process.
