The Third Workshop on Mercury and Sulfur in South Florida Wetlands. This workshop is organized by the South Florida Water Management District, the U.S. Geological Survey and the Florida Department of Environmental Protection. It is intended to support activities under the SFWMD’s Sulfur Action Plan; the USGS’ South Florida Ecosystem Program, and the FDEP’s South Florida Mercury Science Program. Through these programs, the three agencies investigate the effects of elevated mercury and sulfur levels throughout the greater Everglades.
