Water Testing

Boulder County Public Health (BCPH) analyzes water from public water supplies and privately owned wells for Coliform bacteria. The Environmental Protection Agency (EPA) recommends private wells be tested annually.

Our goal is to reduce the potential risk of waterborne disease and illness by providing affordable water testing of community and private water supplies, as well as to provide outreach education.
