When the ESA Phase 1 indicates that there is a risk of contamination that can affect the environmental quality of a site, the Environmental Site Assessment – Phase 2 is necessary.
Soil and/or groundwater samples are taken at strategic locations. They are then analyzed in a laboratory to determine if there really is the presence of contaminants and in which case, if their concentrations exceed the regulation limits.
Sampling techniques vary depending on the material to be removed, access to the site, the depth of the required sampling, structures, etc. For example, a drill and/or an excavator shovel are often used.
In reviewing the results of the Phase 2, qualified personnel at Northex will inform stakeholders concerning the need of remediation of the site.
