Teranis Staff have worked in utility assessment since the mid '90s, well before contamination was a recognized risk to workers, public safety and a major cost to utility operators.  Overlooked and beyond current environmental regulation, Teranis has independently developed site investigation techniques and novel assessment tools to assist utility owners to assess damage and recover the cost of asset impairment or damage.

We have facilitated major utility owners such as TELUS, BC Hydro, Centra Gas, SaskTel, Terasen (FortisBC) and the Cities of Edmonton and Calgary to assess the nature and degree of chemical damage to various underground services.
