When a petroleum or hazardous materials release to the environment occurs, state and federal environmental regulations generally require a phased site investigation approach to determine:

  • If the release is reportable as required by the appropriate regulatory authority;
  • If contaminant concentrations exceed applicable cleanup standards;
  • Potential contaminant migration pathways and rates in the environment;
  • If there are imminent threats to human health, safety or the environment that require immediate response;
  • The nature, magnitude, extent, and fate of environmental contamination; and
  • If remediation or monitoring is required to comply with applicable environmental regulations.

Therefore, a well-designed site investigation that minimizes unnecessary data collection, minimizes sampling, and focuses on meeting specific investigation objectives requires:

  • A thorough understanding of applicable state and federal environmental regulations;
  • Up-to-date knowledge of scientific and investigative methods;
  • An understanding of the fate and transport of contaminants in the environment; and
  • A strong reputation with regulatory agencies resulting in the credibility and trust that are critical to successful negotiation of investigation approaches and “cleanup end points.

EndPoint provides a full range of site investigation services that are founded on our years of experience in dealing with many different types of releases (i.e., petroleum hydrocarbons, chlorinated solvents, heavy metals, and polychlorinated biphenyls) under different state and federal environmental regulatory programs.  Some of these regulatory programs include:

  • Comprehensive Environmental Response, Compensation, and Liability Act (Federal Superfund);
  • Resource Conservation and Recovery Act (RCRA) Corrective Action Program;
  • Toxic Substance Control Act;
  • Massachusetts Contingency Plan (MCP);
  • Connecticut Remedial Standard Regulations (RSRs); and
  • New Hampshire Contaminated Site Management Regulations.

Our professional staff is comprised of many diverse scientific and engineering disciplines including: environmental engineering, hydrogeology, geophysics, geology, hydrology, environmental chemistry, environmental science, and wetland biology.  This diverse background allows us to address specific investigation areas to meet specific objectives and goals.  Whether a release has impacted soil, bedrock, ground water, surface water, wetlands, or indoor air, we have the specific expertise to investigate areas of critical environmental concern so that cost and study time are minimized.
