Water Quality

Water provided by North Marin Water District meets or surpasses every federal or state drinking water standard for safety and aesthetics. The 1996 Amendments to the Safe Drinking Water Act has provisions requiring drinking water suppliers to issue annual reports to their customers on the quality of their drinking water. These Water Quality Reports (or Consumer Confidence Reports) explain what substances have been found in the drinking water and whether the water is safe to drink. A useful site for understanding the information provided in the report is located at: water.epa.gov
