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.

Environmental Remediation Services
for White Sands Missile Range

White Sands, NM
US Department of the Army

HZ Technical Services (a Joint-Venture between Harris Environmental and Zia Engineering and Environmental Consultants) performs all manner of environmental, cultural and biologic services over the entire White Sands Missile Range, New Mexico. Our 12-member staff assists directorates requiring environmental remediation work, Resource Conservation and Recovery Act (ACT) management, National Environmental Policy Act (NEPA) reports for WSMR mission support.

We handle, manage and notify parties for all manner of hazardous waste under RCRA regulations. We also manage and inspect the 90-day yard, multiple Satellite Accumulation Points, hazardous and non-hazardous solid waste management and recycling, waste-liquid requiring sampling, transportation for ultimate disposal.

We collect, manage and report on data for all groundwater sampling and monitoring, coordinate and report sampling results for liquids, solids, sludge, oils, fuels, and air. We also decontaminate buildings, rooms, shacks and transportainers for hanta virus caused by rodent droppings; decontamination requires assessing and then implementing the proper personal protective equipment . We have a 24-hour spill response requiring sampling and cleanup of the liquid spilled, asbestos handling and abatement.

We coordinate and execute all manner of NEPA projects including, environmental assessments (EA), environmental impact statements (EIS), record of environmental concern (REC) and integrated training area management (ITAM).


AZ State Dept of Environmental Quality

Harris Environmental collected samples from and evaluated the physical and biological properties of over 75 streams throughout Arizona. Our protocols adhered strictly to the Arizona Department of Environmental Quality (ADEQ) Standard Operating Procedures for Surface Water Quality Sampling. All samples collected were processed, delivered, and cataloged with sample numbers generated by the ADEQ Water Quality Database on chain of custody forms. Samples included organic and inorganic nutrients, total and dissolved metals, suspended sediment concentration, benthic and water column chlorophyll, algae/periphyton, and macroinvertebrates. Water quality parameters measured also included total dissolved oxygen, percent dissolved oxygen, water and air temperature, pH, specific conductivity, total dissolved solids, turbidity, and E. coli most probable values. Duplicates, blanks, and other quality control samples were collected when needed, and results are used for various state-wide analyses and are available to the public online. Because of our successful completion of this project we were awarded a competitive follow-on contract.

Arroyo Chico Oil Mitigation

Pima County, AZ

Harris Environmental responded to an urban oil spill exacerbated by storm water runoff that carried pollutants downstream. Oil residue and staining was prevalent within urban restoration basins situated just north of a restoration project being monitored. Oil treatment products were used to treat oil pollutants within the county-owned retention basins. Our approach provided a cost-benefit analysis comparing this new treatment strategy for small-scale spills with traditional methods that required heavy machinery to remove and replace rip rap and substrate.
