(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:

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

, 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. The remainder of Munisport site beyond the landfill area unfortunately lies below the mean high water line, further increasing risk. Both inside and outside a dike constructed along the southeastern edge of the property are mangrove swamps. Biscayne Aquifer lies below the ground surface. The flow of regional groundwater is southeastward, towards Biscayne Bay, but varies locally due to mounding.

Documented contamination

For seven years, nearby residents have suffered as wastes were dumped into groundwater and piled up to high. After heavy rains, contaminated water flows from the dump, flooding and contaminating the area. When the EPA originally released their evaluation and report on the Munisport superfund site, it clearly stated that the land should never be developed and that an impermeable "cap" should be placed on the area so that toxic chemicals could not potentially leak into the air, water and soil, as the impact on human and aquatic health were unknown. The original EPA evaluation of the site stated that the onsite samples originally tested contained di(2-ethylhexyl)phthalate, dieldrin, pentachlorophenol, and PCBs. Other samples contained lead, cadmium and ammonia. The ASTDR Public Health report stated: The report stated that the dumping of 2,600 pounds of styrene in 1989, and 12,000 pounds in 198, occurred by just one boatyard. Governmental regulatory agencies at that time indicated that the extent of contaminants on the entire property remained unknown. The report indicated that it was necessary to go down more than two feet below ground (soil had only been tested superficially at one inch deep) to know what was really brewing beneath the surface. There is no evidence that this was ever done. The Public Health Assessment concluded: "Inhalation of contaminated dust is a past and future air exposure pathway. Contaminated soils and fill material are sources of contaminated dust." The Western portion of Munisport Dump was backfilled with solid waste consisting, among other things, of solid waste consisting of trash and municipal garbage. Among the non-permitted dumping discovered and documented were 12 drums containing

Resident exposure to contamination

In the early 1990s Highland Park residents expressed concerns that contaminated soil and water at Munisport has exposed adjacent Highland Village mobile home park, population est. 1,500, by stormwater run-off and contaminated airborne pollution (by dust). In addition, Highland Park residents expressed concerns that children have been directly exposed when trespassing on the site. There was a 1990 landfill fire that residents believe could have caused additional toxic exposure, although air sampling was not done in time.

Documented complaints from adjacent Highland Village

The following are documented complaints from Highland Village Residents after dumping began at Munisport Landfill. *rashes, respiratory illnesses, and infections suffered in the 1970s and 1980s, caused by exposure to dust from landfill. *toxic smoke from the March/April 1990 landfill fire aggravated existing respiratory conditions *increased rates of eye irritation and infection from swimming at the Oleta State Recreation Area and in the lagoon adjacent to Florida International University. *children developed serious skin infections after being cut or scratched. *inordinately high number of cancers in their neighborhood after dumping began
