Nonpoint Source Pollution
Marinas and Boating Activities
A popular recreational activity, boating can also contribute to nonpoint source pollution. Chemicals used on boats may spill into the water; spilled fuel can also contaminate waters around marinas. Click on image for larger view.
Marinas and boating activities can also contribute to nonpoint source pollution. Chemicals used to maintain and repair boats, such as solvents, oils, paints, and cleansers, may spill into the water, or make their way into waterbodies via runoff. Spilling fuel (gasoline or oil) at marinas or discharging uncombusted fuels from engines also contribute to nonpoint source pollution. In addition, poorly maintained sanitary waste systems aboard boats or poorly maintained pump-out stations at marinas can significantly increase bacteria and nutrient levels in the water.
