The findings of a Phase I Environmental Site Assessment will generally determine the necessity for a Phase II Environmental Site Assessment. The primary objective of a Phase II Environmental Site Assessment is to determine whether Controlled Recognized Environmental Conditions that were identified during the Phase I Environmental Site Assessment have resulted in an impact to soil or groundwater at the site.

Phase II Environmental Site Assessments initially begin with soil and groundwater sampling. These samples can be collected by hand, or by small to large drilling equipment. Samples will be collected in locations where a hazardous release is identified and will be used to determine the entire area of soil and groundwater contamination.
