Superfund Site: COKER'S SANITATION SERVICE LANDFILLS
Superfund Site Profile
The Coker's Sanitation Service Landfills site is located in Cheswold, Delaware. The site consists of two landfills used in the 1960s and early 1970s to dispose of waste from the manufacture of latex rubber. One landfill includes an unknown number of unlined trenches. The second landfill consists of 51 lined trenches, a leachate collection system for each trench and a groundwater monitoring network. Operators disposed of an estimated 110,000 cubic yards of waste at the site. These activities contaminated soil and groundwater with hazardous chemicals. Following cleanup, operation and maintenance activities are ongoing. EPA took the site off the Superfund program’s National Priorities List (NPL) in 2011.
