Stormwater Treatment Area One West (STA1W) was constructed to fulfill the goals of the 1994 Everglades Forever Act to improve water quality in the Everglades. The project is monitored in accordance with NPDES and EFA permits from the Florida Department of Environmental Protection (FDEP). The permits include specific conditions requiring the District to monitor water quality at the inflow and outflows of the project. Runoff from the Everglades Agricultural Area is routed through an inflow canal for treatment in the project then discharged to the Arthur R. Marshall Loxahatchee National Wildlife Refuge, located to its east. Phosphorus is naturally removed in aquatic systems by means of deposition and/or is being taken up by aquatic plants.
The water quality data obtained under this program will be used to:
1. Evaluate water quality status and trends;
2. Assess compliance with federal and state water quality statutes, the Everglades Forever Act; and the Everglades Settlement Agreement;
3. Aid in the translation of narratives to numerical water quality criteria to quantify the tons of nutrients removed by the STA annually.
4. Guide mid and long term resource management decision making to augment the nutrient removal capability of the STA to assist restoration of the ecological function of the Everglades.
The inflow site S-5A and the two discharge sites, G310 and G251, have water quality samples collected weekly.
The sampling of inflows and outflows are also done under the project names ST1M for mercury in water, ST1F for mercury in fish, ST1G for pesticides, and ST1D for mercury in sediments.
