Water Quality

Concord General Services' Water Treatment Division provides tap water for the City of Concord of the highest quality. The laboratory staff at the Water Treatment Plant performs continuous testing to ensure the water is within accordance of national standards that are enforced by the U.S. Environmental Protection Agency (EPA) and the Safe Drinking Water Act (SDWA). Division staff ensures these standards are enforced to protect the public from contaminants and to provide the highest standards for both water quality and safety.

Water Quality Reports

Water quality reports, or consumer confidence reports, are published annually to provide a public record of how the City of Concord meets or exceeds all state and federal standards for water quality and treatment. All public water systems have been required to produce an annual water quality report since 1999. The report details the quality of Concord’s tap water, frequently asked questions, a comparison of all regulated water contaminants found against the standards of maximum contaminant levels (MCLs), and other important information.

Partnership for Safe Water

Concord General Services’ Water Treatment Division joined the American Water Works Association (AWWA) Partnership for Safe Water in November 2014 to enhance Concord’s commitment to providing the highest quality water. This is a voluntary four-phase program with established water quality guidelines higher than the minimum standards set by the Environmental Protection Agency (EPA). Our Water Treatment Plant has officially been recognized as a Phase II facility. Being a Phase II facility includes annual data collection and reporting of baseline turbidity results (raw and finished) to the AWWA. Concord General Services’ goal is to reach Phase IV by 2019. Being a partner of AWWA Partnership for Safe Water will ensure that the City of Concord is providing the highest water quality possible for the community and is ahead of federal regulations. Please email Marco Philippon, our Water Treatment Superintendent, for any questions or concerns about the program or the quality of our water.
