Case Study

Phase I, II and III Environmental Assessments & Risk Analyses

Arizona, Florida, Nevada, North Dakota, Oregon, Texas

Hazardous Materials Testing, Containment Assessment, Ground Surveys

National Wildlife Refuge System Mission:

The mission of the National Wildlife Refuge System is to administer a national network of lands and waters for the conservation, management and, where appropriate, restoration of the fish, wildlife and plant resources and their habitats within the United States for the benefit of present and future generations of Americans.

Client Challenge:

to conduct Phase I, Phase II and Phase III Contaminant Assessments to characterize the nature and extent of contamination at sites which have released or threaten to release hazardous substances into the environment.

The Solution:

To start, extensive file reviews, interviews with local landowners, and Mineral Resources Data System (MRDS) database searches published by U.S.G.S. were conducted to identify historical sites at various Wildlife Refuges nationwide which may have released hazardous substances into the environment. These sites included cattle dip pits, treatment tanks, pesticide storage areas, mine tailing piles, slag pits, leach pits, mine tunnels, and/or landfills.

Subsequently a visual reconnaissance of 100% of each Refuge using low level aircraft was conducted. Sites identified during the Phase I Inventory were subsequently visited by our personnel during Phase II to collect and analyze site-specific data. The field work involved ground confirmation surveys, installation of borings / groundwater monitoring wells, development of site specific hydrologic / geologic data; identification / verification of nearby targets and pathways; sampling & analysis; characterization using real-time instrumentation; and development of comprehensive remedial action recommendations. For each site characterized, we developed detailed remedial cost estimates and a recommended course of action.
