NPL Site Narrative for Chemtronics, Inc.
CHEMTRONICS, INC.
Swannanoa, North Carolina
Federal Register Notice: September 8, 1983Conditions at listing (December 1982): The Chemtronics, Inc., Site covers 10 acres in Swannanoa, North Carolina, in the Picrate Branch drainage basin. Two areas are involved. Number 1 consists of eight abandoned acid and organic waste pits used by Chemtronics and its predecessors. Number 2 consists of two lined basins for neutralization and equalization of wastes prior to their discharge into the Metropolitan Sewage District collection facilities.
The pits were closed in December 1979. Five were covered, and three holding liquids were left uncovered. All lie in the drainage basin of Gregg Branch. Two wells monitoring ground water near the pits were contaminated by numerous organic compounds and metals. One well monitoring leachate contained numerous organics, metals, and high dissolved solids. The leachate was also highly acidic. A monitoring well about 100 feet northeast of the site showed a dramatic increase in dissolved solids between April 1981 and March 1982. Lead, barium, cadmium, nitrates, and nitrites were found in excessive quantities, in addition to many identified and unidentified organic compounds.
A basin liner in the second area failed in June 1979, discharging waste into ground water and possibly surface water. In 1980, the liner was replaced. During an inspection of the site, an organic odor was noted in holes drilled to determine the depth to the water table and the nature of the underlying material.
Status (July 1983): EPA is considering various alternatives for this site.
