UNOBTAINABLE

The Tyson's Dump Site, located in Upper Merion Township, Montgomery County, Pennsylvania, is a four-acre abandoned sandstone quarry. The unlined lagoons were used to dispose of septic and chemical waste from 1962 to 1970. In the 1970s, sludges and liquid wastes, primarily chlorinated and other organic solvents, were dumped into the lagoons. The state of Pennsylvania ordered the facility closed in 1973. During closure, the lagoons reportedly were emptied of standing water, backfilled, vegetated, and the contents transported off site, although contaminated soils remained on site. In early 1983, EPA received a citizen complaint about noxious odors emanating from the site. An investigation indicated that the lagoon area soils and groundwater beneath the site were contaminated with organic solvents such as trichloropropane. Among the emergency actions, EPA erected a security fence, leachate was collected and treated, and a partial soil cap was placed over the lagoon area. The contaminated groundwater had migrated beyond the site boundary in the direction of the Schuylkill River. Water intakes for Norristown and Philadelphia are downstream from the site on the Schuylkill River. An estimated 26,000 people live in the residential area surrounding the site. Site Responsibility This site is being addressed through a combination of federal, state, and potentially responsible parties' actions.
