EPA ECHO Public Water Systems quarterly compliance updates are overdue again
While we wait for the Safe Drinking Water Act compliance update, here is a look at California's Impaired Waterways List
The First Revised Proposed Final Staff Report and Responses to Comments for the 2026 California Integrated Report has been released. Revisions have been made to the December 22, 2025 Proposed Final Staff Report. The First Revised Proposed Final Staff Report and Response to Comments can be found , here.
The Califonia State Water Resources Control Board will consider adopting California's Clean Water Act Section 303(d) List portion of the 2026 California Integrated Report on February 3, 2026.
For more information on the meeting, please review the Notice of Board Meeting and Consideration of Adoption of California’s 2026 Clean Water Act Section 303(d) List and Availability of Proposed Final Documents and Response to Comments , here.
An excerpt from a WTCAL.us January 2025 report, here:
The US Environmental Protection Agency audits public drinking water facilities quarterly, providing essential public disclosure on each facility's compliance with Safe Drinking Water Act and the National Primary Drinking Water Regulations. By the time the public sees the latest quarterly data, it is already up to three months old. When these quarterly updates arrive late, the public is left in the dark.
The work to verify and upload compliance data for over one hundred and fifty thousand public drinking water facilities remains behind schedule. Inspection results for the monitoring and reporting quarter ended Sep 30, 2025 should be available to the public in the first two weeks of January. The upload was late for the first time in years, in January 2025, and each quarter following. Public drinking water compliance history data was a month or more late through 2025.
WaterToday Media Group produces the Serious Violator Report based on publicly available information from the EPA. The report includes all facilities with significant violations of the Safe Drinking Water Act, including exceeding Maximum Contaminant Levels during the last monitoring period. WT will continue to watch for the new data set, with a new Serious Violator List covering the period July 1 to Sept 30, 2025. If you have questions about whether your local drinking water provider has been on the Serious Violator list in the past, send us an email at info@watertoday.ca, and also see our last Serious Violator report, here.
The Safe Drinking Water Act requires all public drinking water facilities to issue Annual Water Quality Reports, or, for the smaller facilities, a Consumer Confidence Report. These reports typically emerge in May, covering the previous calendar year's water testing results noting any violations of contaminant levels during that period.
Annual Water Quality Report contains USA EPA Safe Drinking Water Act mandated sections and disclaimer statement, the source of the drinking water, and any discrepancies from the standard during the reporting period. If this is to be your first time opening a Consumer Confidence Report or Annual Water Quality Report, here is a spoiler.
A paragraph common to all reports in some form is the following disclaimer:
"Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers."
Even the drinking water facilities reporting perfect compliance with the Safe Drinking Water Act may have measured quantities of particular substances that may not be advisable for sensitive persons to consume, especially on a long term basis. Make sure to read through the local water quality report for substances exceeding standard. If you have sensitive persons in your household, understand that drinking water meeting standards may not be appropriate for certain people. Look for elevated levels of inorganic chemicals such as fluoride, manganese or arsenic. Be aware of the presence and level of disinfection by-products, ask your health care provider how these factors may affect the members of your household over the long term.
Safe Drinking Water Hotline 1-800-426-4791
EPA/Centers for Disease Control (CDC) issues guidelines on ways for households to minimize the chance of illness from microbial contaminants. Keep this number handy, Safe Drinking Water Hotline 1-800-426-4791. If you believe your water may be at risk for microbiological contamination, check with the water facility about boiling to sanitize the water. Boiling for one minute will clean the water of bacteria or other microbial infections agents, however, if the water is already carrying inorganic chemistry in excess of the standards, boiling will act to further concentrate these elements. When in doubt, make the call.
See prior article on the latest changes to the SDWA, regulation of six PFAS compounds in drinking water, here.
Public water systems regulated under the Safe Drinking Water Act are those providing water for human consumption to at least 15 service connections or average 25 average people per day, for at 60 days per year or more.
See the latest WTCAL.us Serious Violator list, here.
The Safe Drinking Water Act protects public health through the administration and delivery of quality drinking water supplies across the USA. The US EPA establishes standards for drinking water, monitors and enforces treatment techniques for surface water and groundwater, sets maximum limits for around 100 contaminants ensuring public disclosure of deviations and discrepancies.
WaterToday opens the record books of the federal drinking water regulator to bring awareness to the local raw water supply and the compliance record of licensed water treatment facilities. California Water Boards inspect 7417 licensed and active public drinking water facilities, reporting the results to the federal EPA.
