Initial site investigations to record existing conditions to reduce liability.
A non-intrusive site investigation and involves a historical review, site visit, and stakeholder interviews.
Involves a field program to collect soil and water samples to determine type and extent of contamination.
A Phase I assessment is completed to determine the potential for contaminants in soils and groundwater through non-invasive methods.
Depending on the results of a Phase I assessment an intrusive program might be required to determine the exact extent and type of contamination on the site. A Phase II typically consists of 3 parts:
Determining the number, location, and methods to be used to collect samples and install monitoring wells
Drilling or test pits are used to collect soil and water samples to be tested for specific contaminants. Water monitoring wells or piezometers are also commonly installed for future sample collection.
When contamination is found in the from a Phase II assessment, remediation is often required to return the site to within the acceptable levels.
