The use, storage or disposal of raw materials or waste products can contaminate soil and groundwater during operations at an industrial site. The use of human health and ecological risk assessment techniques as an alternative to full scale remediation, or in the absence of criteria, is accepted by regulatory agencies in North America as well as internationally. Through the use of these techniques, when site specific considerations permit, risk management plans and/or site specific clean-up criteria can be developed on a priority basis, thus achieving the greatest reduction of risk in a cost effective manner and also assuring avoidance of undue risks.

Evaluation of contaminated sites is useful in setting priorities, quantifying or otherwise addressing uncertainties, developing risk-based recommendations for remediation and setting risk-based, site specific clean-up criteria.

Site Specific Risk Assessment (SSRA) Services offered include:

• development of site specific clean-up criteria
• human health and ecological risk assessment
• modelling of contaminant transport and uptake
• development of risk management plans
• risk communication
• environmental audits, and
• subsurface investigations.
