372 S HENDERSON ROAD

The Henderson Road site occupies 7 acres in a commercial business area of Upper Merion Township, Pennsylvania. Since 1975, O'Hara Sanitation has used the site for waste storage, waste recycling, vehicle maintenance and parking, and office facilities. A former industrial water supply well was used to dispose of industrial liquid wastes during the 1970s. The injection well lies beneath the floor of the O'Hara Sanitation maintenance garage. Contaminants include volatile organic compounds such as benzene, toluene, perchloroethene, and trichloroethene, and polyaromatic hydrocarbons. Other areas of concern include an area of previously ponded water and a landfill located 200 feet east of the well, containing approximately 158,000 cubic yards of landfill material. Additionally, about 21,000 cubic yards of trash and cinder fill were disposed of on adjacent properties. The landfill did not have a permit and contains a mixture of construction demolition debris and other commercial wastes, cinders, a former trenching area, and four underground storage tanks. Liquid waste, sludge, and drums also may have been disposed of at the landfill. The site is located approximately 2,000 feet upgradient of the Upper Merion Reservoir, a source of drinking water owned and operated by Aqua America, Inc that services over 200,000 people. Apartment complexes and private homes are situated beyond the neighboring industrial facilities of the site. The population residing within one-mile of the site is over 5,000 people. A school is located 3,000 feet south of the site. Site Responsibility This site is being addressed through federal and potentially responsible parties' actions.
