Water Quality Report

About the Water Quality Report


Santa Rosa’s Water Quality Report is also known as a Consumer Confidence Report (CCR), which is a key part of the public’s right-to-know as established in the 1996 Amendments to the Safe Drinking Water Act (SDWA, section 1414(c)). Community water systems (CWSs) are required by Federal regulations (63 FR 44511, August 19, 1998) to provide to its customers a CCR each year.

Community water systems, like Santa Rosa’s, serving 10,000 or more persons are required to mail or otherwise directly deliver these reports. 
The report lists the regulated contaminants found in the drinking water, as well as health effects information related to violations of the drinking water standards. More information on CCRs can be accessed on the EPA's Website and the California State Water Resources Control Board Website.

Public Health Goals Report


The Public Health Goals Report is a California only requirement based on the requirements of California Health and Safety Code Section 116470(b). Public water systems serving more than 10,000 service connections must prepare a brief, written report in plain language that gives information on the detection of any contaminants above the Public Health Goals (PHGs) published by the State Office of Environmental Health Hazard Assessment (OEHHA).

The purpose of this regulation is to provide consumers with information on levels of contaminants even below the enforceable mandatory Maximum Contaminant Levels (MCLs) so they would be aware of whatever risks might be posed by the presence of these contaminants at levels below the MCLs.

Below are the Public Health Goals Reports for 2010 and 2013:

Water Supply Testing


Before drinking water reaches your tap, Santa Rosa and the Sonoma County Water Agency (Water Agency takes many steps to ensure its quality. This includes bacterial disinfection, pH treatment to prevent pipe corrosion, regular testing throughout the distribution system, and on-going maintenance to ensure your water meets or exceeds state and federal drinking water standards.
