Stage of Clean-up: Design Underway
Conditions at proposal (September 18, 1985): Standard CHLORINE of Delaware, Inc., manufactures chlorinated benzenes on a 46-acre site in Delaware City, New Castle County, Delaware. In September l98l, about 5,000 gallons of MONOCHLOROBENZENE spilled from a railroad tanker car onto the Standard CHLORINE property. Subsequent testing by the company and the State has detected chlorobenzenes in on-site soils, ground water underlying the site, and Red Lion Creek, which is about 1,000 feet north of the site. Ground water within 3 miles of the site supplies private and public wells serving an estimated 152,000 people. Standard CHLORINE has retained a consultant to study the site and recommend remedial alternatives. Status (July 22, 1987): EPA's preliminary plan for fiscal year 1987 includes a remedial investigation/feasibility study (RI/FS) to determine the type and extent of contamination at the site and identify alternatives for remedial action. The State is negotiating with Standard CHLORINE to conduct the RI/FS.
Sources of Contamination:
- Discharge to sewer/surface water
- Inadvertent spill
- Waste pile
