In Durham Region, our Phase 2 ESA work covers through on-site drilling, soil and groundwater sampling, and laboratory confirmation of what's actually present. We work from our Vaughan head office, about 43 km from Durham Region, 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 2 ESA page.

A Phase 2 usually follows a Phase 1 — see our Phase 1 ESA page for Durham Region if that step hasn't happened yet.

Common questions

Phase 2 Environmental Site Assessments in Durham Region

How long does a Phase 2 ESA take in Durham Region?

Three to six weeks is typical, depending on site access for drilling and how long lab results take.

How much does a Phase 2 ESA cost in Durham Region?

The number of boreholes, the lab analysis needed and site access all factor into cost. We quote a fixed price for a defined scope before we start.

Which standard applies?

For transactions and due diligence, CSA Z769 is the usual standard; O. Reg. 153/04 governs work feeding into an RSC filing or a permit application.

Does a Phase 2 always follow a Phase 1?

In most cases yes, since a Phase 2 confirms a Phase 1's findings — though a known issue, such as a documented spill, can justify going straight to Phase 2.
