Phase 1 Environmental Site Assessments in Waterloo
Financing and transaction work generally uses CSA Z768-01; O. Reg. 153/04 is required where a Record of Site Condition, rezoning or permit is involved.
Waterloo properties come to us for Phase 1 Environmental Site Assessments to identify potential contamination through a records review, a site visit and interviews — without any sampling. We work from our Vaughan head office, 96 km or so away, so site attendance is straightforward rather than an added cost.
Full detail on the process and what's in the report is on the Phase 1 ESA page.
A Phase 2 ESA follows when a concern is identified — see our Phase 2 ESA page for Waterloo.
