The federal government sues the South Florida Water Management District and the Florida Department of Environmental Regulation alleging violations of state and federal law regarding pollution  (particularly phosphorus) in the Loxahatchee Wildlife Refuge and Everglades National Park. The federal government alleged that the source of the pollution came from four pump stations (S-5A, S-6, S-7 and S-8) that are operated by the SFWMD and divert run-off from the EAA southward into water conservation areas (which include the Loxahatchee NWR).
