A pipe at the Canal Creek Groundwater Treatment Plant at the Edgewood Area of Aberdeen Proving Ground burst early Monday morning because of cold temperatures, sending about 29,000 gallons of untreated contaminated groundwater into a nearby storm drain, APG officials reported Tuesday.
Kelly Luster, public affairs chief for the U.S. Army Garrison at APG, said the pipe broke around 2 a.m. Monday.
"Extremely cold temperatures led to the pipe freezing and ultimately breaking," Luster stated in an e-mail.
The pipe led to a groundwater extraction well. Workers have since repaired the pipe break and APG officials are monitoring the area, according to a news release.
The Canal Creek area is among several sites in the Edgewood Area of APG that were formerly used for testing and disposal of chemical munitions and is subject to an ongoing cleanup and monitoring as a federal Superfund site, according to the Environmental Protection Agency. Drinking water wells in that area were abandoned several years ago, the EPA's Mid-Atlantic Superfund Website notes.
Army officials alerted the Harford County Health Department and the Maryland Department of the Environment about Monday's break, the APG release states.
