EXPERTISE

GSI designs site investigations to cost-effectively obtain the data needed for appropriate corrective action program in cost-effective manner; specializes in Risk-Based Corrective Action (RBCA) and Remediation by Natural Attenuation (RNA) programs; customizes investigations to site-specific conditions and remedial action objectives; manages hydrogeologic site investigations at large and complex facilities involving multiple individual contaminant sources; and performs accurate, high quality, and complete data acquisition safely and efficiently.

REPRESENTATIVE EXPERIENCE

RFI Projects: Conducted multiple RCRA Facility Investigation (RFI) projects, involving from one to more than 100 individual solid waste management units (SWMUs), for major chemical manufacturing facilities in the Gulf Coast and elsewhere in the U.S. with budgets ranging from less than $50,000 to over $1,000,000.

Site Assessments: Conducted numerous projects, large and small, using a wide variety of site screening tools and field tests to provide results on an expedited basis to facilitate rapid decision making for real estate transactions and other time sensitive issues.

NAPL Characterization: Performed accelerated DNAPL and LNAPL delineation studies for a large Superfund Site in Texas and other industrial sites using innovative technologies to minimize potential worker exposure, prevent generation of investigation-derived wastes, and reduce project costs.

Forensic Analysis: Conducted detailed forensic investigation of intermingled hydrocarbon contaminants to assess inter-company liability across property lines.
