Archaeological Monitoring of Contaminated Soil Removal from the Waste Dump Archaeological Site, AZ AA:6:2(ASM), Pinal County, Arizona

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

Year: 2012


ADOA retained URS Corporation to remove and dispose of a mound of contaminated soil from Area A of the Picacho Pesticide Site, which is within a parcel of State Trust land managed by ASLD. The contaminated soil is within an archaeological site known as the Waste Dump site and designated AZ AA:6:2(ASM). The site is the remnants of a large prehistoric Hohokam village that was occupied during the Classic period (circa A.D. 1125 to 1450). Archaeological monitoring was conducted to document any archaeological resources that might be affected by removal of the contaminated soil.

In summary, the archaeological monitoring identified no evidence of archaeological features or intact buried archaeological deposits, and the removal of the contaminated soil did not substantially alter the Waste Dump archaeological site or diminish its potential to yield important information. Nor did use of the CAIDD irrigation canal maintenance road as an alternative access route affect any remnants of the Bull site, AZ AA:6:11/15(ASM). Survey of the access road in conjunction with archaeological monitoring identified a circa 1940s to 1950s trash scatter on State Trust land (just east of the junction of the access road and Harmon Road) that remains unrecorded and unevaluated for Arizona Register eligibility.
