Omega’s staff has decades of experience designing and conducting evaluations of chemical contamination at a variety of sites and geologic settings. A Phase II Environmental Site Assessment (ESA) is a component of environmental due diligence that is critical when buying or selling a property. Omega conducts Phase II ESAs based on industry standard best practices set by the American Society of Testing and Materials (ASTM) which ensure compliance with federal and state regulations.
Omega’s experienced environmental professionals will evaluate the results of a Phase I Environmental Site Assessment to determine if a recognized environmental condition (REC) exists on site which warrants further investigation. ASTM defines a REC as “The presence or likely presence of any hazardous substances or petroleum products in, on, or at a property”. A REC poses a threat if it has been released into the environment, or has the potential to do so in the future. The results of the Phase I will determine the scope of the environmental sampling conducted in the Phase II assessment.
Prior to conducting the evaluation, Omega will ensure the goals of the project are understood and will design the scope of work to meet the needs of the client as well as any banks, lenders, or attorneys involved.
Components of a Phase II ESA
Depending on what was discovered in the initial Phase I ESA, a Phase II may require any of the following investigations to test for a variety of contaminants on a site:
- Surface soil sampling
- Surface water sampling
- Soil vapor sampling
- Subsurface soil boring
- Groundwater monitoring well installation
- Underground storage tank (UST) testing
- Geophysical testing for drums or tanks buried underground
- Sampling contents of drums left on site
- Sampling transformers/capacitors for PCBs
- Evaluations of chemical fate and transport
- Risk assessment and modeling
Laboratory analysis of samples taken during the assessment will determine whether further investigation is necessary. If hazardous chemicals are discovered on site during the Phase II, a Phase III Assessment may be necessary to determine the extent of the contamination.
