Advanced statistical approaches assist in estimating realistic risks with common and emerging contaminants.
We provide human health and ecological risk assessment services as tools to identify the most appropriate approaches to remediate sites impacted by soil and groundwater contamination.
Our practitioners collaborate with toxicologists, public health scientists, biostatisticians, epidemiologists, information management professionals, and contaminant fate and transport modelling specialists to develop site-specific solutions.
We believe that by using science-based approaches, risk assessment can be a powerful tool for site closure, redevelopment planning, and management of environmental liabilities.
Risk assessment commences with qualitative approaches or use of approved guidance (Tier 1). With site-specific information, such an assessment can become increasingly complex (Tier 2 and Tier 3). The assessment process can culminate with verification using biota testing. Alternately, advanced food-web modelling techniques can be used to avoid biota testing entirely.
We assess risks using quantitative or qualitative methods in the following areas:
- Human health
- Hazardous vapours and ground gases
- Chemical fate and transport
