Water Quality & Shellfish


Jefferson County has abundant natural resources, including over 9,000 miles of streams; more than 800 lakes; 230 miles of shoreline; over 18,000 acres of approved commercial shellfish beds, and 40 open recreational shellfish beaches. Jefferson County Public Health’s Water Quality Division was established in 2007 to enhance and protect the water resources of our county. Our mission is to protect public health by monitoring and responding to threats to water quality and protecting human health and wildlife habitat using available local, state, and federal funding effectively and efficiently.


The links in this section will give you more information on the work we do on behalf of county residents and on how you can work with us to prevent water pollution.
