Hydrogeology & Geoenvironmental

Our team of professional engineers, geoscientists and technologists understand the importance of incorporating hydrogeology and geoenvironmental procedures into a project as early as the planning stage continued through to project completion.

Our team has extensive experience coordinating and collaborating with our various groups internally, as well as with regulatory bodies, including the Ministry of the Environment, Conservation and Parks (MECP), Ministry of Natural Resources (MNR) and local Conservation Authorities and Municipalities, at all stages of a project to provide our clients with a complete level of service.

 

Unlocking Hydrogeology & Geoenvironmental Insights for Project Success
