Superfund record of decision (EPA Region 2): Naval Weapons Station Earle (Site A), Operable Unit 3, Colts Neck, NJ, September 29, 1998

Technical Report ·
OSTI ID:350757
This Record of Decision (ROD) presents the remedial action alternative selected for Operable Unit 3 (OU-3) to address soil and groundwater contamination at the Naval Weapons Station (NWS) Earle Site, located in Colts Neck, New Jersey. OU-3 includes the portion of Site 26 comprised of the former process leach tank connected to Building GB-1 and associated soil and groundwater contamination apparently emanating from the tank. The selected remedy for OU-3 consists of the following major components: Excavate and dispose of the process leach tank and adjacent contaminated soils; Treat residual soil and groundwater contamination through the use of air sparging/vapor extraction to remove the larger portion of solvent compounds present to the physically limiting endpoint, followed by monitored natural air attenuation and periodic reviews of progress; Establish a Classification Exception Area (CEA) immediately adjacent to Site 26 to bar the use of groundwater during the remediation period; and Provide long-term periodic groundwater monitoring.
