CONTAMINATED LAND RISK ASSESSMENT SERVICES

We specialise in assessing risks to human health from contaminated land as well as modelling and evaluating contaminant fate and transport in groundwater. Our assessments will give you an indication of likely impaction times, derive soil and groundwater clean-up targets and evaluate remediation options.

We take a tiered approach to risk assessment, beginning with the construction of a conceptual site model and where necessary, ending with a highly site specific quantitative risk assessment.

Conceptual models are helpful as they describe all the sources, pathways and receptors that are likely to be associated with a particular site and therefore help to focus the risk assessment. Data on human exposure characteristics, contaminant concentration and distribution as well as contaminant fate and transport is then collected. A range of exposure assessment models (i.e. CLEA, RD20, SNIFFER, JAGG, RBCA) can then be used to predict human exposures to contaminants, evaluate the significance of the risks to health and derive soil clean-up targets. The information gained from the risk assessment is then used to evaluate remediation options.

Recognising the importance of effective risk communication, we tailor our reports to the target audience, ensuring that the risks associated with a site are clearly presented and easily understood.
