Water Quality Reports & FAQs

Water Quality Reports

The City of Fountain Valley vigilantly safeguards the water supply. The water delivered to your home or business meets or exceeds the quality standards required by federal and state regulatory agencies. Pursuant to the California Safe Drinking Water Act, the City monitors over 100 contaminants in the water supply. The results of this testing are published in the City's annual Water Quality Report which is available online by July 1 every year. A postcard is sent to every mailing address in the City notifying residents and businesses that the annual report is available online. Click on the links provided on the right to view the current and past water reports. 

If you would like the current report mailed to you, please call 714-593-4600, or email your name and address to Christine.Smith@FountainValley.gov or Kevin.Deason@FountainValley.gov with the subject line: Water Quality Report.

Lead Service Line Inventory

Per the Lead and Copper Rule Revisions (LCRR) published by the U.S. Environmental Protection Agency (EPA), all water systems are required to complete a service line inventory by October 16, 2024, of both utility-owned and privately-owned service lines, to identify lines that contain or possibly contain lead.

The City of Fountain Valley completed its Lead Service Line Initial Inventory (LSLI) in accordance with the U.S. EPA's LCRR. No lead or galvanized requiring replacement service lines were observed. Click here for more information.

Water System Flushing Program
In addition to continually monitoring the quality of the City’s water supply, the City performs routine water system maintenance to ensure reliability, water quality and emergency preparedness. An important part of this routine maintenance is Water System Flushing, a standard industry practice used by water agencies to maintain high-quality water throughout the system.

Flushing operations are required on a regular basis by the California Department of Public Health. During flushing, crews discharge water at maximum velocities. This rapid movement of water scours pipe walls to remove residue, eliminates “aged” water, increases chlorine residuals, removes sediment and improves water quality, taste and odor.
