Assessment and Investigation

  • phase I/II environmental site assessments
  • soil, groundwater, and surface water investigations
  • geologic and hydrogeologic characterization
  • vapor intrusion assessments
  • landfill gas investigations
  • waste characterization

From relatively straightforward Phase I ESAs to support property transactions to more comprehensive subsurface investigations to determine the nature, extent, and magnitude of affected media at Superfund sites, INTERA applies a focused, solution-oriented approach to every assessment and investigation project. By focusing on the end goal of the project, whether it is regulatory compliance, closure, or redevelopment, the scope of our investigative programs is developed to provide the information needed for risk-based decision-making. This may mean implementing investigative activities in phases or collecting additional data during an investigation that is important for early screening of potential remedial solutions. INTERA’s data collection efforts involve gathering information on the chemical and physical nature of site contaminants, the distribution of contamination and migration pathways, and site geologic and hydrogeologic data to build an accurate conceptual site model. We use various approaches to evaluate and present the data, including GIS and model simulations of groundwater flow and contaminant fate and transport.

Whether it is investigating a specific issue, such as acid rock drainage at a mine site or methane gas generation at a landfill, or addressing soil and groundwater contamination from past industrial waste management practices, INTERA’s assessment and investigation activities are aimed at reducing environmental liabilities. The information obtained from our assessment activities is followed by expert advice. We draw upon expertise gained from investigating and characterizing hundreds of sites that include Brownfields, petroleum storage tank (PST) sites, federal and state Superfund sites, mining complexes, landfills, military installations, nuclear material production and weapons testing facilities, petroleum refineries and tank farms, chemical plants, and other industrial facilities. When contaminants are detected, we determine the nature and extent of the problem and work with clients to design the most effective course of action.
