Remediation Effort Continues

Schlage Lock continues to operate numerous onsite and offsite remediation systems with great success, cleaning up PCE in soil and groundwater. Onsite treatment systems including Soil Vapor Extraction (SVE), recirculating sparge wells (ART), and sparge wells continue to reduce PCE concentrations in the source areas. Also onsite, groundwater extraction wells continue to cut-off the migration of PCE-containing groundwater at the property boundary. Offsite, the cut-off system at Bradley Road continues to stop the migration of PCE-containing groundwater into the Widefield Aquifer. In the Widefield Aquifer, PCE concentrations in groundwater are decreasing and at some locations have already met the State’s drinking water standard. At Willow Springs Ponds, Schlage Lock operates two surface water aerators that are maintaining surface water concentrations below the State’s “fish plus water” standard for PCE.  Schlage is also operating an air sparge treatment system to treat groundwater before entering Willow Springs Pond No.1.  Schlage Lock is committed to protecting the environment and continues to work closely with the Colorado Department of Public Health and Environment to ensure the remediation technologies it uses are the most appropriate.
