A discussion of the uncertainties for all components of the risk assessment are also included in the risk characterization. The goal is to provide this information reflecting transparency in the decision-making process, clarity in the communication, consistency with other assessments, and reasonableness. The risk characterization serves as the bridge between the assessment of potential risks from the site and the risk management decision concerning the potential need for remedial actions. Remedial actions . Risk assessment results are used by the Project Manager to determine the need for further action based on criteria in the National Contingency Plan.
Risk assessment is used to determine whether the goals protect public health.
The remedial action alternatives and associated technologies are screened to identify those that are effective for the contaminants and media of interest at the site. The information developed in these two activities is used in assembling technologies into alternatives for the site as a whole, or for a specific portion of the site. In determining the remedial site actions, each alternative is assessed against specific evaluation criteria and the results arrayed to allow comparisons between alternatives. The first two criteria are threshold determinations and must be met before remedy selection. The next five criteria are balancing criteria and the last two criteria are modifying criteria.
