Just as with Phase 1, the difference between a <\/span>Phase 2 Canadian Standards Association (CSA)<\/b> and a <\/span>Phase 2 Record of Site Condition (RSC)<\/b> in Ontario is essentially the difference between “private due diligence” and “regulatory law.”<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Phase 2 involves “intrusive” testing (drilling boreholes and installing monitoring wells) to sample soil and groundwater.

      1. You cannot easily “upgrade” a CSA report to an RSC report later. If there is even a small chance you will need an RSC (e.g., for future rezoning), it is often cheaper to do it to the RSC standard from the start.\u00a0<\/span><\/li>
