Phase II Environmental Site Assessment (ESA)
Subsurface Soil Investigation
If a Phase I ESA identifies potential contamination of a property, a Phase II Environmental Site Assessment may be conducted to determine the value and marketability of the site. This practice is used for liability purposes in a wide variety of legal, regulatory, and commercial contexts. With a Phase II ESA, Midwest Environmental Consulting Service, Inc. (MEC) obtains scientifically valid data concerning actual property conditions, and whether or not such data relate to conditions previous identified as recognized environmental conditions (RECs) or data gaps in the Phase I ESA.
MEC is dedicated to providing comprehensive Phase II Environmental Site Assessments to clients throughout the United States. This process includes sampling and analysis to confirm the presence or likely presence of hazardous materials in the subsurface of the site a. Depending on the results, MEC will outline additional investigation needs and possible remedial actions required to clean up the property in a Phase III ESA.
Surficial soil, air, and water samples
Groundwater monitoring well installation
A sampling of dry wells, floor drains, and catch basins
Transformer and capacitor sampling for Polychlorinated Biphenyls (PCBs)
Geophysical testing for buried tanks, utilities, and drums
Testing of underground storage tanks
Vapor intrusion analysis
Risk analysis and modeling
Contaminant pathway evaluations
Indoor air quality sampling
Standards for the Phase I, Phase II, and Phase III Environmental Site Assessments have been established by the American Society for Testing and Materials (ASTM) to address the “All-Appropriate-Inquiry” (AAI) aspect of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
Substances examined during the ESA include those within the scope of the CERCLA, pollutants, contaminants, petroleum and petroleum products, controlled substances and their related components.
Phase II ESA Objectives
Evaluate whether or not there has been a release of hazardous substances within the definition of CERCLA, for purposes including landowner liability protections
Identify, define, and evaluate property conditions associated with contaminants that may pose a threat to human health or the environment, or contribute to the risk of bodily injury to people on the property
Provide information relevant to identifying and implementing landowner obligations to prevent or limit exposures to hazardous substances
Provide information relevant to business environmental risk in transactional and contractual contexts including transferring ownership, financing, and insuring the property
Develop knowledge of the contaminants on the property within the scope of the CERCLA definition of a “brownfield site” and as required for qualifying for brownfields remediation grants from the EPA Brownfields Program
Provide information to support disclosure of liabilities in financial statements and securities reporting
