Archaeological Monitoring of Contaminated Soil Removal from the Eloy Airfield, Pinal County, Arizona

Author(s): Chad V. Kirvan; A.E. (Gene) Rogge; Ronald D. Savage

Year: 2011

Summary

Historical aerial photographs indicate the abandoned Eloy Airfield was developed prior to 1959 and ASLD records indicate the parcel of State Trust land on which the airport was located was leased to commercial crop dusting services from 1969 to 1981. Site investigations conducted between 1993 and 2006 documented that the parcel was contaminated with organochlorine pesticides, primarily toxaphene. In 2009, State Risk Management, which provided oversight and funding for environmental remedial action at the former airfield, retained URS Corporation to excavate, transport, and dispose of pesticide contaminated soil exceeding the nonresidential soil remediation level for toxaphene (16 milligrams per kilogram).

A prehistoric Hohokam archaeological site, AZ AA:6:51(ASM), overlaps the airfield parcel. ASLD, in consultation with SHPO, determined that site AZ AA:6:51(ASM) is eligible for the Arizona Register under Criterion D because it has potential to yield important information about the Hohokam occupation of the Santa Cruz Flats. ASLD in consultation with SHPO and ASM agreed that pursuant to the State Historic Preservation Act and Arizona Antiquities Act some level of archaeological study should be conducted to recover and preserve information and artifacts in areas of the site that could not be avoided by the removal of contaminated soil. Because of the contamination, both agencies recognized that normal archaeological excavation could pose a hazard to archaeologists and they agreed that data recovery could be limited to archaeological monitoring. This report documents the goals, methods, and results of the approved monitoring plan.
