Superfund Site Profile
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.
