Abstract
The Chemical Sales (New Location) (Operable Unit 2) site is an active chemical sales and storage facility in Commerce City, Adams County, Colorado. Land use in the area is predominantly industrial. The site is a portion of a 4-square-mile-area, which consists of single and multi-family residences, small business, municipal facilities, and agriculture, and undeveloped land. Between 1985 and 1990, three onsite chemical releases of hazardous substances from the CS facility into onsite soil and ground water were documented. First in 1985, approximately 200 gallons of methylene chloride were released during a chemical transfer second, in 1986 VOC-contaminated rain water was discharged into a nearby drainage ditch. And this in 1990, approximately 3,700 gallons of methanol were spilled onto the ground near the CS tank farm. The site has been divided into three operable units (OUs) for remediation. A previous Record of Decision (ROD) addressed onsite soil and ground water contamination as OU1. This ROD addresses OU2, the VOC-contaminated ground water plume, which is north of Sand Creek. The primary contaminants of concern affecting the ground water are VOCs including benzene, PCE, and TCE. The selected remedial action for OU2 of this site includes pumping and onsite treatment of ground water using air stripping, followed by onsite reinjection of treated water into the aquifer; annual ground water monitoring; and voluntary abandonment of bedrock wells.
