Army Drilling Deep Wells to Test Valley Bedrock for Perchlorate

Second deep well being drilled at 4820 Glenbrook Road

Two new wells bored 200 feet below Spring Valley represent the latest step in an ongoing effort by the U.S. Army Corps of Engineers to determine the source of groundwater contamination and where that contamination is spreading. The Army Corps has been studying Spring Valley's groundwater since 2005 and has found, just below the ground, concentrations of the chemical perchlorate that significantly exceed drinking water standards ... The planned Kreeger Hall excavation should determine that source, according to [Army Corps project manager Todd] Beckwith. A survey over the summer with advanced metal detectors found "anomalies" that could be buried Army waste causing the contamination, he said.
