Phase II Assessments

<< Back to Our Services

A Phase II Environmental Site Assessment (ESA) may be necessary when either possible or actual surface or subsurface contamination has been suspected or identified at a property.

  • The Phase II ESA will generally be composed of the following:
    • Development of a work plan identifying potential chemicals of concern and investigation objectives,
    • Surface and/or subsurface sampling and analysis of soils and water using the following methods to investigate, delineate, and characterize contamination:
      • Soil sampling via direct push systems or mechanical drill rigs,
      • Installation of monitoring wells via direct push systems or mechanical drill rigs, and
      • Groundwater sampling from monitoring wells.
    • Data evaluation is performed by comparing the concentrations of the chemicals of concern to an applicable regulatory action level,
    • Documentation is prepared detailing methodologies used, results, conclusions, and recommendations, and
    • Communicating (as appropriate) with the applicable regulatory agency at the local, state, and federal level.
  • Our experience in developing and implementing subsurface investigations means you will be provided with the information you need to evaluate risk and make informed business decisions.
