The Effectiveness criteria evaluates the state of development of the technology, the ability to protect human health and the environment based on the following criteria:
- Protectiveness: the degree of protection each technology provides to human health and the environment. If a remedial action alternative is to be effective, and reliable over the long-term, it must be protective;
- Permanence: the degree to which the alternative permanently reduces either the toxicity, contaminant availability (or mobility), and the volume of contaminants;
- Management of Short Term Risks: the effectiveness of the process in dealing with the potential impacts to human health and the environment during the implementation phase; and
- A qualitative or quantitative assessment of the adequacy and reliability of any institutional or engineering controls based on professional judgment, taking into consideration the performance history of these controls.
Effectiveness measures the performance of the alternative up to the point in time that remedial action objects are achieved and implementation is complete. Whether the risk management option can maintain these goals/sub-goals over the long -term is assessed by the next factor "long term reliability".
