WHAT WE DO
Teranis has a strong background in ambient air quality assessment for fugitive emissions from stationary and mobile sources, including: emissions from pulp mills, refineries, light manufacturing, dry docks, transportation (exhaust & road dust) and gas blow-down sites. Teranis has also provided statistical analyses of emissions data to assess the efficacy of emissions control systems and conversion of boilers to alternate fuels.
Teranis specializes in providing First Nations with environmental consulting services related to contaminated land investigation and remediation. Teranis' approach with First Nations communities is to actively engage community members in the environmental assessment process for their own land.
Teranis staff have worked in utility assessment since the mid '90's, well before contamination was a recognized risk to workers, public safety and a major cost to utility operators for infrastructure replacement. Overlooked by 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.
FORENSIC HYDROCARBON FINGERPRINTING
This technique is used to determine the nature, degree of weathering (i.e. age), and source of petroleum hydrocarbon contamination. Ultimately, this information is used to identify responsible parties and more fairly apportion remediation costs at sites where multiple sources of contamination may be present.
While typical environmental services appear conventional and routine, it is the attention to detail that provides clients with solutions and regulatory compliance; economically and efficiently. Teranis has significant experience in the assessment and remediation of contaminated sites under both the federal and BC Provincial regulatory regimes.
With more than thirty years of combined experience involving the investigation, management and remediation of elemental and vapour-phase mercury, we have conducted over fifty investigations for Public Works and Government Services (PWGSC), the Canadian Coast Guard, FortisBC, a multinational oil company, laboratories within educational facilities, and a former smelter.
Due to mercury's high volatility, the management and remediation of elemental mercury contamination requires considerable knowledge and an extremely meticulous approach to prevent recontamination of buildings or inadvertent human exposure.
LANDFILL ASSESSMENT & UNDERGROUND FIRES
Teranis has considerable experience in the assessment of landfills and their emissions of leachate and gas. We have conducted landfill monitoring for closure plans and mitigation of potential impact to receptors. Aerobic waste decomposition can cause landfill waste to heat up until spontaneous combustion occurs. Underground fires may be identified from unusual waste settlement over a short period of time, visible smoke, a burnt odour and elevated carbon monoxide concentrations in monitoring wells. Teranis has developed a number of investigative tools to identify the nature, location and extent of underground fires and can provide advice on the most appropriate control measures.
