Look Up Drinking Water Data

The Federal Safe Drinking Water Act (SDWA) standards apply to all water systems providing water for human consumption to the general public. This may include residences without a private well, as well as places of business that have their own well(s). Public drinking water system data such as requirements, sample results, violations, etc. can be accessed and downloaded. Public water systems serving residences are also required to provide an annual Consumer Confidence Report (CCR), which includes information regarding the water quality and their compliance with the SDWA. Contact your municipality for further information and a copy of their CCR.
