Superfund Record of Decision (EPA Region 10): American Lake Gardens (McCord AFB - Area D), Pierce County, WA. (First remedial action), September 1991. Final report
The American Lake Gardens (McChord AFB-Area D) site is an active U.S. Air Force base located at McChord Air Force Base, Pierce County, Washington. The site consists of two areas, Area D and American Lake Garden Tract (ALGT). From the mid-1940's to the present, no known industrial activities have occurred in the ALGT area; however, seven waste disposal sites have operated within the Area D portion of the site. Concurrent with DOD investigations, EPA discovered TCE in ground water monitoring wells installed at the ALGT, and in 1984, concluded that waste disposal sites in Area D were the likely source of ground water contamination. The ROD addresses remediation of the contaminated onsite and offsite ground water plume, as a final remedy. The primary contaminants of concern affecting the ground water are VOCs including benzene, PCE, TCE, toluene, and xylenes; other organics; and metals including arsenic, chromium, and lead. The selected remedial action for the site is included.
