Per Public Law 106-554, the U.S. Army Corps of Engineers is authorized to provide technical and financial assistance to carryout projects for the planning, design, and construction of storm water and wastewater treatment works to improve water quality in the Florida Keys National Marine Sanctuary. As population and tourism in the Keys have increased over the years, wastewater and storm water treatment and management practices have not kept up with available technology. Nutrients from wastewater are one of the contributing factors to the decline of the water quality in both the canals and nearshore waters surrounding the Keys. The primary purpose of this effort is to improve water quality in the Florida Keys, by the implementing wastewater and storm water master plans previously prepared for Monroe County and various municipalities within Monroe County, Florida. The authorized Federal cost is $100 million.

Municipalities included in the Florida Keys Water Quality Improvements Program are Key Largo, Key Colony Beach, Marathon, Islamorada, Layton, and Key West.
