Site Investigations (Phase II)

An environmental site investigation (Phase II) is conducted to assess the presence, type, and extent of contamination in soil, soil gas, and/or groundwater. Site-specific characteristics such as geology, depth to groundwater, and other site features are also evaluated at this phase. This data will be used to develop cost-effective and efficient remediation strategies, if needed.

GRI has conducted numerous soil, soil gas, and groundwater investigations at various contaminated sites, including:

  • Underground storage tank sites
  • Aboveground storage tank sites
  • Automotive repair shops
  • Dry cleaners
  • Metal plating shops
  • Manufacturing facilities
  • Refineries
  • Other contaminated sites

GRI can prepare the required work plans and summary reports, coordinate with subcontractors, obtain necessary permits, communicate with regulatory agencies, and provide other technical support.
