The 18-acre Wasatch Chemical Co. (Lot 6) site is located in Salt Lake City, Utah. From 1957 to 1971, Wasatch Chemical Company used the area to warehouse, produce and package industrial chemical products. Between the 1970s and 1992, site operations included blending and packaging pesticides, herbicides, fertilizers, industrial chemicals and cleaners. The company also discharged wastewater into on-site tanks, evaporation ponds and onto the ground. These activities contaminated soil, sludge and groundwater with hazardous chemicals. Following cleanup, operation and maintenance activities are ongoing.
