Phase 2 Environmental Site Assessments in London

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.

We carry out Phase 2 Environmental Site Assessments in London with boreholes, monitoring wells and laboratory testing to confirm or rule out contamination flagged in a Phase 1. Site attendance is routine rather than a special trip, with our Vaughan head office 173 km or so away.

For the complete process and report structure, see the Phase 2 ESA page.

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

What triggers a Phase 2 ESA

A documented history of any of these usually points to a Phase 2.

Underground storage tanksPresent or historic USTs are one of the most common reasons a Phase 2 is recommended.
Dry cleaning historySites with a documented dry cleaning history carry a real likelihood of solvent contamination.
Vehicle service or fuel salesA history of auto repair or fuel retailing points strongly toward soil or groundwater impact.
Industrial or manufacturing useLegacy industrial operations often leave contamination worth confirming before it's relied on.

Common questions

Phase 2 Environmental Site Assessments in London

How long does a Phase 2 ESA take in London?

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 London?

Cost is driven by the number of sample locations, lab work required, and site access, priced to a defined scope before work begins.

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.
