Environmental Site Assessment Services

Phase I Environmental Study

A Phase I Environmental Site Assessment consists of a historical review of all activities of a property. This study is typically performed in the course of real estate transactions or with mortgage refinancing.

Phase II Environmental Study

A Phase II Environmental Site Assessment occurs when a risk of contamination is detected during the Phase 1 study. This phase involves surveying for sampling and chemical analysis of groundwater and/or soil.

Underground Storage Tank Removal

Removal of underground storage tanks is often required to improve the environmental status of the property. Our team provides pumping, cleaning, dismantling and disposal of tanks. We also locate tanks if needed.

Environmental Remediation

Environmental remediation is required when a property with contaminated soil or water must be excavated. We provide full disposal services, studies on the toxicological risks and detailed reporting on the remediation work conducted.


When testing for Asbestos is required, we provide everything you need, including “Vrac” and “Air” tests. Vrac results are provided within 10 days of a site visit, while air results are available daily.


Ensuring building hygiene includes testing for mold and toxic species on surfaces and in the air. Using accredited laboratories and advanced detection equipment, we analyze air quality, gather samples, and provide timely reporting.


Radon detection ensures that buildings are free of harmful radioactive gasses. Using state-of-the-art equipment to measure levels in a property, we will provide risk assessment within minutes of conducting tests, and offer solutions.
