Environment Site Assessments (ESA's)

Site AssessmentE-21 Engineering, Inc. personnel have conducted several hundred Phase I Environmental Site Assessments (ESA's). Site properties have ranged from small undeveloped single parcels to large multiple parcels with extensive heavy industrial manufacturing facilities and large, multiple commercial property sell-off transactions by major petroleum retailers.  These services have been performed for various entities, including petroleum retailers, lending institutions, insurance companies, Federal, State and County agencies, developers, major corporations, other engineering consulting firms, construction firms, law firms, real estate agents and private individuals.

We use the latest ASTM Standard Guide for Phase I ESA's. This standard provides the due-diligence effort required in ESA's for property transactions. Our ESA's for property transactions are prepared in general accordance with the updated standard including All Appropriate Inquiries (AAI).

E-21 can provide time and cost effective Phase II contaminant investigations through the implementation of a tiered investigative approach. This method utilizes a single-step approach using smaller-scale investigative tools to initially identify the presence of contamination. If contamination is identified a more thorough investigation is undertaken to adequately quantify the levels and vertical and horizontal extent. Once established, economic and feasible measures can be evaluated for site remediation. The tiered-approach allows for the timely and cost effective evaluation of contaminant releases.
