Superfund Record of Decision (EPA Region 9): Castle Air Force Base, Merced County, CA. (First remedial action), August 1991

Technical Report ·
OSTI ID:7303249
The 2,777-acre Castle Air Force Base is a Strategic Air Command training base 6 miles northwest of the City of Merced in Merced County, California. Land use in the area is predominantly agricultural. Since 1941, the site has been used as a military air training base. Fire training activities, as well as aircraft and jet engine maintenance activities including metal plating and processing, have occurred onsite. In 1984, the base was required not only to implement remedial measures to correct the identified contamination but also to prevent future ground water degradation from waste discharges. The site has been divided into operable units (OUs) for remediation. The Record of Decision (ROD) provides an interim remedy for the main TCE plume, as OU1. Future RODs will address remaining soil and ground water contamination. The primary contaminants of concern affecting the ground water are VOCs including benzene, PCE, and TCE. The selected remedial action for the interim remedy is included.
