Waste water treatment plant nearly back to normal operation
By DAN KULIN
Hagerstown's sewage treatment plant was operating at near pre-shutdown levels after a successful switch back to using ozone to disinfect the waste water on Monday, Plant Superintendent Donald Barton said.
The plant was 80 percent to 85 percent back to normal, and with the use of ozone the waste water flowing from the plant into Antietam Creek was "very close to pre-shutdown levels," Barton said.
Plant operations should be back to normal by Feb. 25, he said.
The city plant was partially shut down Feb. 9 after the bacteria used to help treat sewage were killed when at least hundreds of gallons of chemicals commonly found in industrial cleaners, insecticides, paint and other manufacturing products were dumped into the sewer system.
Barton said city and Maryland Department of the Environment officials are trying to find out where the chemicals came from. The MDE has asked that anyone who saw suspicious activity or dumping into the sewer system call 301-739-8068.
