soil vapour intrusion 

Helping you meet your regulatory obligations

Where volatile chemicals have contaminated soil and groundwater below buildings, there is the potential for these vapours to enter the building.  Dry cleaning fluids such as trichloroethylene, perchloroethylene, and components of petroleum hydrocarbons (such as benzene) can migrate with groundwater and ultimately create vapour issues in buildings.  These issues are often associated with former industrial properties (brownfield sites).

We are currently providing engineering support to the largest soil vapour mitigation project ever undertaken in Ontario.  We are also supporting brownfield development where soil vapour mitigation is part of the required Risk Management Measures.


We can help you meet your regulatory obligations and realize the potential of your brownfield development.
