Because of water's different sources and the different ways in which water is treated, the taste and quality of drinking water varies from place to place. Over 90 percent of water systems meet EPA's standards for tap water quality. The best source of specific information about your drinking water is your water supplier. Water suppliers that serve the same people year-round are required to send their customers an annual water quality report (sometimes called a consumer confidence report). Contact your water supplier to get a copy or see if your report is posted on-line. For additional information, visit EPA's websites on local drinking water (provides links to state and local sources of water quality information) and drinking water and health (provides information on drinking water contaminants and their health effects).
