Munisport Landfill is a closed landfill located in North Miami, Florida adjacent to a low-income community, a regional campus of Florida International University, Oleta River State Park (a state recreational park), and estuarine Biscayne Bay. The Munisport landfill contains approximately 6.2 million cubic yards of municipal waste, and was in operation for seven years. Munisport was found to contain contaminants, and a "small amount" of hospital biohazard waste was found on the site and drums of toxic chemicals during its operation. Audubon Society compiled a list of chemicals Munisport employees admitted had been buried in the dump. Environmental Protection Agency (EPA) officials never detected dangerous levels of those in the landfill and concentrated their efforts on the mangrove preserve south of the site, where the chief concern was the seepage of ammonia, created naturally as organic debris decomposes. The 1992 Consent Decree between the City of North Miami and the United States redefined and shrank the National Priorities List boundaries of the site to a site is in wetlands to the east, away from the actual dump. In 2011, Munisport was designated by the EPA as a site ready for use and redevelopment. Location: North Miami, Florida Congressional District: 22 Current ownership City of North Miami, Florida. History Current status Brownfield. Location Munisport is about northwest of Biscayne Bay. Munisport is bordered on the north by Northeast 151st Street., on the south by N.E. 135th Street on the east by Florida International University, and on the west by Biscayne Blvd. Description Munisport Landfill comprises some , containing 6.2 million cubic yards of municipal, biohazardous, and industrial waste. It is a registered Superfund site. There are 4 areas: a landfill, of uplands, of altered wetlands, and adjacent to Biscayne Bay that are separated from the rest of the site by the State of Florida mangrove preserve Environmental risks The Munisport Landfill is located about from Biscayne Bay. Natural soils in the landfill area had been removed prior to dumping, increasing risk of pollution seepage, especially into the Biscayne Aquifer, a primary source for drinking water in South Florida. The solid waste was disposed of without the use of a liner and with no leachate control mechanisms, so rainfall percolating through the solid waste has caused the release of elevated levels of ammonia and other contaminants into the underlying groundwater and discharges into adjacent surface water.
