Key Optimization Components:  Monitoring

Key Optimization Components Key Optimization Components Remedy Components Monitoring is conducted at any stage of the remedy. During the investigation or design stages, monitoring provides information that helps develop or refine the conceptual site model (CSM). Monitoring during remedy implementation or operation is primarily used to evaluate remedy performance, remedy compliance with relevant environmental and health and safety regulations and remedy progress in meeting established remedial action objectives (RAO). Monitoring during remedy implementation and operation stages also provides useful information to help update and refine the CSM as a measure of evaluating remedy protectiveness and progress.
