A Phase III Environmental Site Assessment essentially is: “We know that the site is contaminated; now let’s see how bad it is.” Typically, a network of boreholes is drilled on a grid system in the contaminated zone. Once delineated, a volume of contaminated soil and/or groundwater can be calculated, and remediation options with cost estimates can be designed and proposed.
The scope of work for a Phase II or III ESA can be tailored to the type of property and likely types of contaminants of concern that may be present.
Typical investigations may include:
- Shallow Vapour Soil Surveys
- Soil Sampling
- Monitoring Well Installation and Ground Water Sampling
- Underground Storage Tanks
- Fuel Tank Removal and Site Remediation
- Leaking Underground Storage Tanks
- Hazardous Building Materials Assessment.
