Risk Assessment

One of the most difficult questions to answer when dealing with an environmental case is "how clean is clean enough?" This question arises frequently because it is not always economically feasible or physically possible to remove contaminants to below detectable concentrations. The identification of this reality has led to the risk assessment process.

 

Risk assessments are designed to consider a large number of site specific factors (e.g., land use, depth to groundwater, soil type, exposure duration, etc.) the carcinogenic and non-carcinogenic risks associated with specific site contaminants, and the potential routes of contaminant exposure. Consideration of these factors results in the calculation of site specific carcinogenic and non-carcinogenic risk factors.

 

Results from such an analysis can be used to develop risk-based corrective actions that protect the health and safety of the community, meet stringent regulatory requirements, and allow for the safe redevelopment of the property.

 

WPI personnel have participated in hundreds of such assessments, and understand when a risk based approach is appropriate as well its usefulness and limitations. This knowledge ensures that risk assessment results are presented in a meaningful manner, and that the scientific principals used in their preparation are not violated or misconstrued.
