At Rescan, we realize the importance of tailoring the scope of a risk assessment to client needs. We employ a phased approach which includes problem formulation to develop a conceptual model and identify stressors of concern, followed by screening level risk assessment. If necessary, more detailed assessment can be provided to resolve issues. Traditional knowledge and traditional use are combined with land use in human health effects assessment. Communication with regulatory agencies is initiated early in the process to ensure that the assessment approach will adequately address agency concerns.
