    Stage of Clean-up: Emergency Removal of Contaminants / Remedial Assessment Not Begun

    The Ryeland Road Arsenic site is located in Heidelberg Township, Berks County, Pennsylvania. The former facility, which encompasses approximately 7.33 acres, currently comprises several residential properties. Arsenic, copper, and lead contamination has been detected in surficial soils on these properties, with arsenic levels exceeding health-based benchmarks, and in nearby surface waters. Copper and lead also have been found in residential drinking water wells at levels exceeding health-based benchmarks. From 1920 to 1940, Standard Chemical Works Corporation (SCWC), and subsequently Allegheny Chemical Corporation (ACC), manufactured pesticides, paints, varnishes, and sulfuric acid. The pesticide manufacturing facility was located on the north side of Ryeland Road. After the shutdown and demolition of the pesticide facility, the property was subdivided into four parcels, that now each contain a residential home. The pesticide facility also owned the parcel of land on the south side of Ryeland Road, which has remained undeveloped. As part of the pesticide manufacturing process, arsenic was converted to arsenic acid; by-products included lead arsenate, calcium arsenate, and copper acetoarsenate. Wastes generated during the manufacturing process were reportedly disposed of on both the north and south sides of Ryeland Road.  More...
