Due Diligence

Identifying and quantifying environmental risks can be a critical part of many business transactions. GSI's staff have provided environmental due diligence services to corporate transaction teams and outside counsel across the U.S. and around the globe. Our staff have provided these services on the acquisition and divestiture of stock and assets, mergers, refinancing, and a variety of other business transactions. The markets we serve include oil and gas, power (fossil fuel and alternative energy), industrial, transportation, and real estate.

Environmental Due Diligence Assessment

GSI conducted an environmental due diligence assessment related to an acquisition transaction and related financing for oil and gas exploration and production assets. We identified potential environmental conditions that may not have been compliant with Railroad Commission of Texas or Texas Commission on Environmental Quality regulations pertinent to oil and gas exploration and productions areas, as well as conditions in excess of a cost materiality threshold developed in cooperation with the client.

Due Diligence Assessment of an Abandoned Oil Field Waste Disposal Facility

GSI completed an engineering design and cost estimate for environmental services associated with the potential development of a 92-acre abandoned oil field waste disposal facility to a 292-parcel residential development and an ecological preserve. This work was completed as part of the due diligence effort associated with the potential acquisition of the property.

Due Diligence of a Former Industrial Property

GSI investigated soil and groundwater conditions present on three tracts of oil production and industrial property within the boundaries of a canal. We characterized impacted soils and groundwater, and evaluated measured contaminant concentrations to criteria established under the Texas Risk Reduction Program (TRRP).

Indoor Soil Gas Investigation

GSI completed a limited sub-slab indoor investigation of soil gas at three sub-sample locations in an apartment complex. We evaluated the presence or absence of volatile organic compounds (VOCs) in shallow soil gas and compared the results to two indoor air samples to determine if a vapor intrusion concern was indicated.
