Surface Water

The surface water program conducts surveys of the Halifax River, St. John’s River, and the Mosquito Lagoon water basins. This water quality monitoring program is called for in the County of Volusia Growth and Resource Management to judge the continuing health of these systems. Data generated by the program is reported to the U.S.E.P.A. national water quality database and used by state, local and federal agencies as well as individuals.
