Stormwater Treatment Area 6 (STA-6) is located in Hendry County just north of the Big Cypress Seminole Indian Reservation. It was the first of the six Stormwater Treatment Areas required by the Everglades Forever Act. STA-6 Section 1 was designed to provide a total effective treatment area of approximately 1.4 square miles (3.5 km2), serving a drainage basin of approximately 16 square miles (km2) of agricultural production area primarily used to grow sugar cane. STA-6 began full operation on December 9,1997. It occupies an existing detention area associated with the United States Sugar Corporation (USSC) Southern Division Ranch. The source of water for STA-6 comes solely from the USSC Unit 2-pump station G600.
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 nutrient 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 G600 and the two discharge monitoring sites, G354C & G393B, have water quality samples collected weekly.
The sampling of inflows and outflows are also done under the project names ST6M for mercury in water, ST6F for mercury in fish and ST6D for mercury in sediments. Pesticides are collected under the STA6 project code.
