Environmental Site Assessments


The Environmental Site Assessment (ESA) is associated with real estate due diligence. The Phase I ESA allows the Client to satisfy one of the requirements of the Innocent Landowner Defense, as defined by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). In accordance with the American Society for Testing and Materials (ASTM) guidance, the goal of the due diligence process is to identify recognized environmental conditions (RECs) on a particular property.

ACES personnel has conducted and reviewed hundreds of Phase I ESA's throughout the State of Texas, which assists our Clients in meeting their real estate due diligence. Representative properties include urban land, rural land, illegal landfills, oil & gas properties, and portfolios of multiple commercial properties. In the event that a Phase I ESA indicates a high probability of a REC, a Phase II ESA (an environmental site investigation), which typically includes soil and groundwater sampling, can be performed to further evaluate potential concerns and needs for corrective action.

ACES assists many clients in assessing RECs identified during the ESA, as well as quantifying the potential business environmental risk on impacted properties. ACES experience with ESAs allows us to provide investigations, regulatory requirements, and we provision of services at a reasonable cost and in a timely manner.
