MoE Certified Human Health and Ecological Risk Assessment

Steer Environmental conducted a human health and ecological risk assessment of chromium and polycyclic aromatic hydrocarbons in soil, and methyl tert-butyl ether in groundwater at the site of a former auto parts recycling operation. The objective of the assessment was to determine if soil and groundwater contamination presented an unacceptable risk to human health or the environment, ultimately to facilitate redevelopment of the property as a commercial warehouse facility.

The assessment evaluated contaminant exposures by the public, commercial workers, trespassers, construction workers, utility workers and ecological receptors. Risks to human health and the environment were determined to be negligible assuming the following risk controls are in place: Current Vacant Scenario: public access restrictions, no vegetation in areas of PAH contaminated soils; Future Commercial Scenario: contaminated soils covered by slab-on-grade buildings, pavement, or a minimum one metre thick clean soil cap.

A MoE Certificate of Compliance was issued for the property based on the findings of the risk assessment and maintenance of the identified risk controls.
