The 8-acre Drake Chemical site is located in Lock Haven, Pennsylvania. A chemical plant operated on site from the 1960s to 1981. The plant made chemical intermediates for pesticides and other organic compounds. Original site structures included 60 process tanks and reactors and 10 large tanks used for bulk storage of acids, bases and fuel oils. The site also included two lined wastewater treatment lagoons and two unlined lagoons. Site operators filled open areas on site with chemical sludge and contaminated soil. Site activities contaminated soil, groundwater and on-site structures with hazardous chemicals. Following cleanup, operation and maintenance activities are ongoing.
