Environmental Investigations


Sierra Vista, AZ
The Nature Conservancy/US Department of Defense

Harris Environmental conducted six Phase I Environmental Site Assessments in Cochise County, Arizona. Most of the properties were historic cattle ranches bordering the Fort Huachuca Military Installation and were characterized by a variety of environmental conditions from vacant undisturbed land to areas with significant use and potentially hazardous environmental contaminants. In total, we investigated 7,776 acres. Two of the ranches were part of The Nature Conservancy’s acquisition plan Surveys of two other ranches was completed in support of acquisition for inclusion into the San Pedro Riparian National Conservation Area and funded by the U.S. Department of Defense and U.S. Department of Homeland Security. The final two ranches, the Bella Vista Ranch and Babacomari Ranch, were investigated in support of transference to the Bureau of Land Management, and the studies were funded by the U.S. Department of Defense – Army Compatible Use Buffer Program. Our reports were reviewed by The Nature Conservancy, Bureau of Land Management, and Department of Defense.


White Mountain Apache Tribe, White River, AZ
US Bureau of Indian Affairs

Harris Environmental conducted Phase 1 Environmental Assessment, Asbestos Survey, UST Investigation, Radon Investigation, Lead Base Paint Survey, and Property Condition Assessment for Building 84, a former Police Station, on the White Mountain Apache Reservation, Arizona, as part of the BIA’s property transfer to the Tribe. The property consisted of a 22,226 square foot building built in 1966 and renovated in 1989. We worked closely with the Tribe and the BIA the conduct the surveys, and to follow up on remediation recommendations.


Yuma, AZ
US General Services Administration

Description of Services Performed: Harris Environmental with sub-consultant SCS Engineers, conducted soil sampling and investigation services at the Yuma International Airport (YIA) in Yuma, Arizona on a former helipad site at the former Yuma Air Branch Facility. This investigation was performed to evaluate whether the soils at the former helipad, which was used by the United States Customs and Border Protection Office of Air and Marine, were contaminated with petroleum constituents. Two known fuel spills (140 and 40 gallons) were documented north of the helipad and in the northeast portion of the site. While there were no documented fuel spills on the helipad; with nearly 30 years of continuous refueling operations, soil could potentially have been impacted by repeated small-scale spills of Jet-A fuel. Fifteen soil borings were drilled using directpush (Geoprobe®) technology operated by Johnson Environmental Technologies. Collection and analysis of soil samples identified low concentrations of several PAHs in three surface samples; however, none of the results exceeded established Arizona soil remediation levels.
