In a Feasibility Study, information generated during the site characterization and risk assessment studies is used evaluate alternatives for cleanup. One important step in most to feasibility studies is to identify clean-up goals or remedial action objectives, which are the goals for protecting human health and the environment at the site and/or for complying with regulatory requirements. The remedial action objectives specify contaminants and media of concern, potential exposure pathways, and preliminary remediation goals. Once the remediation goals have been established, various approaches for site management are identified. The general approaches are those that will satisfy the remediation goals, and might include: no action monitored natural attenuation containment (i.e., conventional or reactive capping) complete or partial removal (dredging) of contaminated sediments with on-site or off-site treatment or disposal.
The preferred treatment approach is then identified based on consideration of factors such as effectiveness, practicability, environmental impacts, acceptability by regulators, and relative cost.
