EPA Superfund Program: BERKLEY PRODUCTS CO. DUMP, DENVER, PA

Superfund Site Profile

The 5-acre Berkley Products Co. Dump site is located in Denver, Pennsylvania. From the 1930s until 1965, this site was a privately owned landfill that accepted municipal wastes to be burned or buried. In 1965, Lipton Paint and Varnish Co., a subsidiary of Berkley Products Co., bought the site and used it to bury municipal waste along with some organic solvents, paint wastes, resins, and pigment sludge. When operations ceased in 1970, the site was covered with soil, seeded and sold. It was estimated that the landfill contains over 103,000 cubic yards of mixed wastes.
 
Contamination was in the site soils and runoff, and leached into the on-site groundwater. There are approximately 25 homes bordering the site that use private home wells for their water supply. None of the surrounding home wells have displayed site-related contamination. The Cocalico Creek passes by the site to the north and east and is a potential receptor for surface water running off the site. However, studies conducted in the creek have shown no indication of contamination. There is a supplementary public water intake located on the Cocalico about two miles downstream of the site that serves an estimated 2,000 people. The community around the site is primarily rural.

This site was proposed to the National Priorities List (NPL) on June 24, 1988 and formally added to the list March 31, 1989. It was deleted from the NPL on March 19, 2007.

TOPICS IN FOCUS

Five Year Review

EPA is in the process of completing the Third Five-Year Review for this site.  Five-Year Reviews generally are required by CERCLA or program policy when hazardous substances remain on site above levels which permit unrestricted use and unlimited exposure. Five-Year reviews provide an opportunity to evaluate the implementation and performance of a remedy to determine whether it remains protective of human health and the environment.

The Third Five-Year Review found a contaminant known as 1,4 dioxane in groundwater in multiple site monitoring wells.  A protectiveness determination of the remedy at the Site cannot be made at this time until further information is obtained. Further information will be obtained by taking the following actions:

  • Define the extent of 1,4-dioxane and metal contamination in groundwater. Determine if site groundwater discharges to Cocalico Creek or migrates beyond the creek to downgradient receptors at unacceptable levels. Upon completion of the groundwater investigation, determine the appropriate remedial action.

It is expected that these actions will take approximately one year to complete, at which time a protectiveness determination will be made.
