The Safe Drinking Water Information System (SDWIS) contains data about public drinking water systems. You may use the SDWIS Query Form to obtain data about the system that provides you water.
You may also learn about the quality of water delivered to your community through annual reports that are mailed, printed in a local newspaper, or posted in a common area. A community public water system is one that serves at least 25 people or 15 residences year-round. This classification includes cities, towns, villages, subdivisions, water and sewer districts, and mobile home parks. Systems delivering water to over 100,000 consumers are also required to make their reports available on the Internet. If your system is large, you may review the annual report in Where You Live .
Your water system may also provide you with Public Notification if instances of noncompliance with certain drinking water requirements occurs.
