Sometimes a Phase I ESA will identify RECs or potential RECs, and additional work is recommended. Advance information about conditions on a given site may warrant immediate consideration of more a more in-depth and/or invasive evaluation. The environmental consulting profession uses the term Phase II ESA for those evaluations and investigations that supplement and/or follow Phase I ESAs and provide a more accurate characterization of potential issues of environmental concern. ALWI’s Phase II ESA services generally follow ASTM Standard No. E 1903-97 as well as other standards as the specific scope may warrant. Our Phase II ESAs can include more detailed record reviews or historical evaluations as well as various types of drilling and sampling programs.
