ESE provides lender approved ASTM-E1527-21 and similar Phase I Environmental Site Assessments and related transaction screens which are often required when a property is externally financed. The purpose of a Phase I ESA is to identify Recognized Environmental Conditions (RECs) associated with a parcel of commercial real estate with respect to the range of contamination within the scope of CERCLA and petroleum products.

A Phase II Environmental Site Assessment is often warranted when a Phase I ESA identifies a Recognized Environmental Condition, requiring further investigation. The purpose of a Phase II ESA is to confirm or deny the presence of chemicals of concern in the environment. The Phase II ESA involves the sampling and laboratory analysis of multiple medias, often including soil, soil gas, and groundwater. The analytical testing results are compared to regulatory limits and criteria established by the applicable government agency. Further remedial action may be warranted based on the results of the Phase II ESA.
