Proposed Army Cleanup Would Demolish Glenbrook Road House

The U.S. Army Corps of Engineers is recommending tearing down a Spring Valley home to identify and remove World War I-era munitions and chemicals feared to be buried beneath it. Since 2000, the Army Corps has removed more than 500 munitions items, 400 pounds of laboratory glassware and more than 100 tons of soil contaminated with arsenic and other hazardous substances from 4825 Glenbrook Road, officials said.

In 1918, 4825 Glenbrook Road was a dumpsite for chemical and explosive munitions and related debris; officials believe a pit was disturbed when the home was built, scattering that material throughout the property. The Army is now proposing to clean up whatever it finds beneath the home to a depth of 12 feet, spending an estimated $12.5 million to restore the site to residential standards.

Campus Groundwater Sampled in Ongoing Perchlorate Investigation

No Entry: Source Area Investigation
The installation of sixteen temporary wells at American University in the vicinity of Kreeger Hall was completed in an effort to identify the source of elevated perchlorate levels in the groundwater in this area. The wells were installed, sampled and closed during a three-week period in July ... Also this month, data generated from the first quarterly sampling effort in May at existing groundwater monitoring wells and surface water locations, such as creeks and streams, was reviewed.

Drilling for Groundwater at Source Area #2
The field team plans to conduct the second quarterly sampling effort the first week of August to assess whether seasonal fluctuations affect contaminant levels in groundwater within the Spring Valley project area. Three new deep groundwater monitoring wells are expected to be installed later this year to determine if perchlorate has migrated into the deeper groundwater flow areas.
