Stage of Clean-up: Construction Underway
Monterey Park, California Conditions at proposal (October 15, 1984): Operating Industries, Inc., operated a landfill on 190 acres in the City of Monterey Park, Los Angeles County, California. The 45-acre northern section was separated in the 1960s from the southern 145-acre section by the Pomona Freeway. EPA has evidence that the original landfill included at least a portion of both sections. From l948 to l983, solid and liquid wastes, some hazardous, were disposed of at the site. Leachate generated by the landfill contains VINYL CHLORIDE, benzene-type compounds, TETRACHLOROETHYLENE, HEAVY METALS, and other contaminants, according to testing by the Los Angeles County Sanitation District (LACSD), the California Department of Health Services (CDHS), and the company. In July l983, the South Coast Air Quality Management District (SCAQMD) detected VINYL CHLORIDE above ambient standards in air at and around the landfill, which is adjacent to a large residential area. SCAQMD, CDHS, and the Los Angeles County Department of Health Services have taken enforcement actions against the facility. About 23,000 people use wells within 3 miles of the site as a source of drinking water. More...
