A phase 1 Environmental Site Assessment is aimed primarily at identifying signs of actual or potential environmental contamination through an intensive study of current and past uses of the site or property.
Following analytical results of samples taken during a phase II, a phase III will concentrate on defining a sampling pattern that will allow to establish the extent of the contamination. In a phase III soil sampling aims at constructing a grid (or mesh) to delimit the contamination in surface and in depth.
For environmental remediation works, a phase III is important to estimate the amount of soil to be decontaminated and therefore reduce the associated costs.
