The Delineated Contamination Areas Program is a cooperative effort between state agencies under the overall supervision of the Florida Department of Environmental Protection (DEP). DEP has the responsibility of identifying, or delineating, areas of groundwater contamination.
Where available, all new dwellings and establishments constructed within the delineated areas must connect to a public water supply. However, if such is not available, a permit must be obtained for the construction of a water supply well to serve the residence or establishment.
Stricter construction standards are required by the water management district to minimize potential contamination. The county health departments are responsible for the sampling and clearance of potable water wells constructed in these areas.
