Baltimore County has almost 200 miles of tidal coastline as well as public and privately owned and operated tidal and fresh water recreational bathing beaches. In addition, the availability of these recreational water resources supports a significant number of related activities such as commercial and recreational fishing, skiing, camping and boating.

Environmental Health Services (EHS) conducts recreational water sampling, provides water sampling in support of sewer overflow investigations and regulates bathing beaches and public swimming pools for the health and safety of the public.
