Step 10: Long-term monitoring

Long term monitoring (LTM) is used to confirm that the nature and extent of the remediation/risk management (R/RM) activities have been carried out as per the R/RM goals and that R/RM activities will continue to meet the R/RM goals for the foreseeable future. The overall goals of LTM for aquatic contaminated sites include the evaluation of the effectiveness of the R/RM activities and the documentation of ecosystem recovery (e.g., the reduction of human health and environmental risks to acceptable levels, the effectiveness of mitigation measures to protect fish habitat).For more information, refer to the Executive Summary of the Federal Contaminated Sites Action Plan (FCSAP) Long-term Monitoring Planning Guidance.

LTM can be terminated when there is a defensible “no” to the question “Will the contaminated aquatic site pose an unacceptable human or ecological risk in the foreseeable future, such that further management action is required?”.

The closure of a site is closely tied to the design of the monitoring program. The components of a monitoring program (i.e., monitoring objectives, monitoring tools and exit criteria established at the start of the program) are used to determine when the remedial goals have been achieved. Site closure occurs when all management objectives are attained.
