KAHLOTUS RD & HWY 12
The Pasco Sanitary Landfill (PSL) property is 280 acres in size, located about 1.5 miles northeast of Pasco, Washington. PSL operated as an open burning dump from 1958 to 1971. Sanitary landfilling began in a 40-acre unlined area in 1972, operating until it was placed under interim cover in 1992. Another portion of the property received hazardous wastes between 1972 and 1975; this portion now resides in five separate cells. Two of these cells collectively contained approximately 40,000 drums containing paints, resins, herbicide and pesticide manufacturing wastes, caustic chemicals, and other wastes. Three of these cells accepted bulk liquid waste and sludges in unlined lagoons, where the wastes were dried and later covered with a RCRA-compliant cover system. Groundwater beneath and downgradient of the property is contaminated primarily with volatile organic compounds (VOCs). These include chlorinated solvents such as tetrachloroethene (Perc), trichloroethene (TCE), their degradation by-products, and other non-chlorinated organic compounds, such as Benzene, Toluene and Xylenes. Other organic compounds and inorganic constituents also have been detected. Groundwater within 3 miles of the site is used by over 1,000 people for drinking and irrigation of 10,000 acres of cropland. A groundwater protection area has been established by the City of Pasco to restrict groundwater usage within the area where landfill-related compounds may be present. Site Responsibility: This site is being addressed through state and potentially responsible parties' actions.
