Phase I Environmental Site Assessment (ASTM 1527-13)
A Phase I Environmental Site Assessment (ESA) is an investigative tool used in identifying potential environmental liabilities at a property. For the buyer and/or lender of a property, a Phase I ESA is the core product for environmental due diligence. Phase I ESAs are prepared for real estate and business transactions to provide assurance that there is no soil or groundwater contamination present from previous use or nearby sites that may impact the property value – something you don’t want to learn about after you buy the property.
Phase II Environmental Site Assessment (ASTM 1903-11)
Generally, a Phase II ESA is recommended when a significant potential of contamination is found during the Phase I ESA process. Intrusive testing is performed on the property as part of the Phase II investigation in order to determine if contamination/hazardous materials are present.
Our Phase II projects follow recommendations of the American Society for Testing and Materials (ASTM) E1903-11 and State and Federal requirements. We can design a scope of work that best fits the situation and the client’s goals and budget. These projects are conducted by experienced environmental scientists and/or Professional Geologists with specific experience in hydrogeology and contaminant fate and transport.
The scope of work for a Phase II can range from a Limited Phase II investigation to a Comprehensive Site Assessment, that include soil sampling and the installation of groundwater monitoring wells with extensive testing. Phase II investigations may also include other testing methods, such as an Asbestos Survey, Lead-Based Paint Inspection, or a Vapor Intrusion Assessment, which evaluates indoor air quality that may be affected by the presence of contamination in the subsurface.
Transaction Screens (ASTM 1528-14)
A Transaction Screen is a limited environmental assessment for a parcel of commercial real estate that is administered when the client wishes to conduct limited environmental due diligence (that is, less than a Phase I Environmental Site Assessment). A Transaction Screen is a useful tool in providing environmental information on properties where no environmental assessment would otherwise be performed.
We perform Environmental Transaction Screens in accordance with the American Society for Testing and Materials (ASTM) Standard E1528-14. The Transaction Screen is commonly used to investigate non-industrial properties of modest values in order to provide the prospective buyer a degree of comfort regarding potential environmental issues.
The Transaction Screen consists of a questionnaire for the site owner, occupants, and the environmental assessor supported by an environmental database review and limited historical search work. The limitations of a Transaction Screen are that it will not satisfy the requirements of the Environmental Protection Agency (EPA) All Appropriate Inquiries (AAI) Rule, which is a statutory requirement to obtain Landowner Liability Protections (LLPs) under CERCLA.
