FORMER ANDERSON FORMAL WEAR SITE
Project Name: Former Anderson Formal Wear Site, Commerce City, Colorado
Date Project Began: September 2001
Date Project Completed: February 2005
Project Description: Mr. Terry McGowan of Casey Resources, Inc. (CRI) was the principal investigator for the Former Anderson Formal Wear Site in Commerce City, Colorado. This facility was the distribution center for the formal wear and also included a dry cleaning operation. Mr. McGowan designed and completed several site investigations to identify the source area of contamination and the extent of groundwater impact. Anderson's consultant proposed a soil vapor extraction system for remediation of the property, which was not accepted by the owner of the property. Mr. McGowan and Mr. Casey prepared an Integrated Corrective Action Plan (ICAP) for remediation of the site and also provided expert witness testimony as part of the legal issues associated with the property. Mr. McGowan managed the implementation of the ICAP which included the excavation of tetrachloroethene (PCE) impacted soil from beneath and in front of the building, and the removal of approximately 20,000 gallons of PCE impacted groundwater. Groundwater monitoring continued for one year on a quarterly basis with the final results showing that all offsite monitoring wells contained PCE concentrations below or just above the groundwater standard for PCE. Mr. McGowan negotiated with the Colorado Department of Public Health and Environment (CDPHE) to obtain an Environmental Covenant for the property which limited any use of groundwater, and released the owner from continued groundwater monitoring.
Type of Contamination: PCE contaminated soil and groundwater.
