Water Quality

Jefferson County Public Health’s Water Quality Division was established in 2007 to enhance and protect the lakes, streams, and marine waters of our county. Our mission is to protect public health by monitoring and responding to threats to water quality for protection of human health and wildlife habitat by using available local, state, and federal funding effectively and efficiently. Jefferson County has abundant natural resources, including over 9,000 miles of streams, more than 800 lakes and 230 miles of shoreline. A Clean Water District was established to help protect water quality and shellfish beds in eastern Jefferson County. Clean Water Projects focus monitoring and pollution correction efforts in areas needing attention. Toxic bluegreen algae is a recurring problem in some of our lakes. Testing is done to make sure that recreational shellfishing areas are safe from biotoxins caused by harmful algae blooms. Saltwater beaches are monitored in the summer for bacteria levels to ensure swimming is safe.
