Santa Rosa Water presents 2024 water quality report; finds no PFAS detections
Summary
Water quality manager presented the 2024 consumer confidence report, described monitoring programs and test results, and said Santa Rosa Water met state and federal standards and reported non‑detect results for 29 PFAS compounds tested under UCMR requirements.
Tony (Antonio) Yamas, Santa Rosa Water’s water quality manager, presented the utility’s 2024 water quality (consumer confidence) report to the Board of Public Utilities and said the report was posted online and distributed through targeted outreach earlier in the week.
Yamas summarized the city’s monitoring and compliance framework: monthly system monitoring, compliance with the Total Coliform Rule and Disinfection Byproducts Rule, and the triennial Lead and Copper Rule testing cycle (the city said lead and copper testing was occurring at the time of the presentation). He said the city’s groundwater production contribution has increased since 2021 and described the Farmers Lane treatment plant’s seasonal operation and green sand filtration process for iron and manganese.
On contaminants of current interest, Yamas said Santa Rosa Water tested for PFAS under the EPA’s UCMR (Unregulated Contaminant Monitoring Rule) programs and reported non‑detect results for all 29 PFAS compounds on the 2024 UCMR list. "The results for all 29 PFAS on that list, came back as non detect," he said. He also noted that the EPA established enforceable limits for some PFAS compounds in April 2024.
Yamas explained key report terms (MCL, DLR, public health goal) and said the report lists primary drinking water standards (those with health concerns) and secondary standards (aesthetic parameters such as taste and odor). He said the supplier — primarily Sonoma Water with about 93% of supply and the Farmers Lane wells providing the remainder — remains in compliance with state and federal rules and had no public health goal exceedances that would trigger a three‑year public health goal report.
Board members asked about replacing a removed park water fountain and requested a hard copy of the report for the board; Yamas said hard copies will be provided on request and that the department would email the board the missing report copy.
A member of the public, Janice Carmen, praised Santa Rosa’s water quality record. No formal board action was taken; the presentation closed and staff will distribute the full report to board members.
