NPL Site Narrative for Koppers Co., Inc. (Florence Plant)

Florence, South Carolina

Federal Register Notice:  September 21, 1984

Conditions at listing (September 1983): Koppers Co., Inc., treats and preserves wood with creosote and pentachlorophenol on a 20-acre site in Florence, Florence County, South Carolina. The company has had numerous difficulties in the past with contaminated run-off. The primary problem at this site, however, is an old evaporation lagoon closed since 1979. It has led to contamination of six of nine monitoring wells on-site, according to company data. The State has detected contamination in private wells off-site. At least 1,200 people use the shallow aquifer for drinking water. Surface water contamination has not been documented to date. In October 1981, the State issued a Consent Order requiring the company to conduct a ground water study.

Status (June 1984): The State is reviewing the company's response to an amended Consent Order which calls for the company to (1) complete installation of a monitoring well, (2) report on the progress of a sampling program, (3) submit a hydrological report, and (4) submit a plan for remedial action.
