The 20-acre Bally Ground Water Contamination site surrounds the former Bally Engineered Structures (BES) plant in Bally, Pennsylvania. From 1972 to 1995, BES manufactured insulated panels for refrigeration on the site. The company�s predecessor, Bally Case and Cooler, Co., disposed of solvent wastes in on-site lagoons. Site activities contaminated groundwater with hazardous chemicals. Following cleanup, operation and maintenance activities are ongoing.
