Why do I need a Phase 2 Environmental Site Assessment (ESA) when I have already paid for a Phase 1 ESA?

Why do I need a Phase 2 Environmental Site Assessment (ESA) when I have already paid for a Phase 1 Environmental Site Assessment (ESA)?

Phase 1 and Phase 2 ESAs are related but very different in scope.  You most likely need a Phase 2 ESA because a Phase 1 ESA has identified the potential presence of contamination or recognized environmental conditions (RECs) on the property.  Or a Phase 2 ESA may be required by environmental regulations or as part of due diligence when there is a property transaction.  Either way, an environmental consultant will conduct a Phase 2 ESA to confirm the presence or the absence of contaminants and to determine the extent and severity of any concerns found on the property.  A Phase 2 ESA is much more extensive than a Phase 1 ESA and will include these key aspects when deemed appropriate by the consultant:

  1. Sampling and Analysis: Samples are collected from the soil, groundwater, and surface water, and sometimes, air samples are taken for testing.  Once collected, the samples are sent to a lab to identify the presence and concentrations of pollutants or hazardous substances.
  2. Site investigation: The assessment involves a detailed examination of the property to determine if contaminants have spread and where.
  3. Risk Assessment: A risk assessment is conducted to evaluate potential risks to human health and the environment of any contaminants found on the property, depending on their concentration.
  4. Remediation Recommendations: Once environmental concerns are identified and their extent is known, the consultant will provide recommendations for appropriate actions.  The goal is to clean up the contamination and restore the site so it is deemed safe per the intended use and for the property owner to comply with relevant environmental regulations.
  5. Final Report: The consultant will summarize the findings, methods used in the site investigation, lab results, and recommendations.  The report is necessary for regulatory compliance and for potential property transactions.

The Phase 2 ESA provides valuable information about the property to the property owner, developers, banks, and regulatory authorities to help make informed decisions about how the property can be used in the future and any liabilities that may be associated with the property.  A Phase 2 ESA is well worth the cost; it may save you a lot of money.
