Extreme rainfall caused a sewage overflow Thursday at a wastewater treatment plant on the Edgewood area of Aberdeen Proving Ground (APG).
Rainfall of about two inches in 24 hours led to roughly 3,000 gallons of partially treated sewage to overflow from tanks at the plant and into King's Creek and the Bush River, according to a news release from APG.
APG officials notified the Harford County Department of Health and Maryland Department of the Environment, and took steps to mitigate the exposure to people in the area, according to the release.
"Lime was applied to the affected area and signs were posted indicating 'No Fishing, No Crabbing, No Shellfish Harvesting, No Swimming,' in the area until further notice," the release stated.
APG Edgewood area officials will monitor the impacted area, the release said.
