Drinking Water Watch
Some state agencies responsible for drinking water have begun posting information about the water systems they regulate on their websites. These Drinking Water Watch sites usually include the physical characteristics of the water systems and the violations and enforcement actions taken by the state. In many cases, these web sites also provide a way for the public to obtain more detailed information about the concentrations of contaminants found and reported by systems to the state. Each site has a link at the bottom of the main page that will allow the user to search for a consumer confidence or water quality report for public water systems within that state.
Please keep in mind that the availability of data varies by state. Some states do not publish these data on their public websites.
