on a property.  If no contaminants are found, a Phase III ESA is not necessary.  However, if contaminants are found, a Phase III ESA take the information from a Phase II and determines the extent of contamination of the property.  It is a much more detailed investigation of the property, and I necessary to uncover additional information before remediation work can take place.

A Phase III ESA should allow parties involved to develop a plan of remediation, which needs to have the approval of local, state, and federal environmental agencies.  It will also detail a full scope of options, including time and costs, for all parties involved with cleanup.

Environmental Professionals at OES will typically conduct additional testing to determine the extent of pollution on the property.  Common tests may include:

  • Groundwater testing
  • Subsurface soil assessment
  • Vapor intrusion
  • Assessment of potential contaminant pathways in soil and groundwater
