Overview
Optimization Stages: Remedy
Optimization during remedy implementation (Remedial Action [RA] and Long-term Response Action [LTRA] in the Superfund Program) uses existing data to update the CSM and compare actual remedy performance to design expectation. Recommendations are provided to improve protectiveness, reduce cost and facilitate site closure. To learn more about the related Superfund pipeline stages, visit Remedial Action
and Long-term Response Action .
To see information about optimization for the other pipeline or optimization stages, visit Investigation stage, Design stage or LTMO stage.
Following are example types of data analyses performed during an remedy stage optimization:
- Analysis of historical data plus trends in performance monitoring data
- Interpretation of the conceptual site model (CSM) and identification of data gaps
- Statistical analysis of groundwater monitoring data
- Review of existing performance monitoring program for gaps and redundancies
- Comparison of current chemical loading and/or other site conditions to conditions considered during design
- Comparison of remedy performance to expected performance and reasonable expectations
- Review of remedy component performance relative to expectations and expectations for competing technologies
- Preliminary capture zone analysis for pump and treat (P&T) systems
- Review of known receptors and potential for additional receptors since remedy design
- Consideration of alternative remedy components and expected cost and performance
- Consideration of supplementary or alternative remedies and expected cost and performance
- Review of provided costs relative to expectations and cost for similar sites
- Preliminary green remediation environmental footprint analysis
