The chemical spill that caused the partial shutdown of the Hagerstown sewage treatment plant last month cost the city government about $40,000, Plant Superintendent Donald Barton said Wednesday.
The costs incurred included about $8,000 for chlorine and dechlorination chemicals to disinfect the waste water passing through the plant, $3,000 for additional laboratory testing of sewage samples, and as much as $20,000 in labor costs, he said.
Barton said that operations at the plant were back to pre-shutdown levels, and he expects the signs warning the public to stay away from Antietam Creek to come down on March 15.
The sewage treatment plant off Frederick Street was partially shut down Feb. 9 after high concentrations of chemicals common to industrial cleaners and other industrial products were dumped into the sewer system, killing the sewage-eating bacteria used to break down complex bacteria and chemicals at the plant. Barton said officials don't know who dumped the chemicals into the sewer system.
