Superfund Site Profile
Five-Year Review Report, September 2016 (PDF) is now available.
The 7.3-acre Ryeland Road Arsenic site is located in Berks County, Pennsylvania. The site consists of five parcels of land. Four of the parcels are on the north side of West Ryeland Road, where Standard Chemical Works Corporation (SCWC) and Allegheny Chemical Corporation (ACC) made pesticides, fungicides, paints and varnishes, and disposed of waste. Private residences were located on these four parcels. The fifth parcel is a vacant lot on the south side of West Ryeland Road, where SCWC and ACC disposed of waste. Past operations contaminated soil and groundwater with arsenic, lead and other chemicals. Investigations and cleanup activities at the site are ongoing.
