Overview
Optimization Stages: Investigation
Optimization during site assessment and remedial investigation (RI) focuses on developing an improved conceptual site model (CSM) to facilitate the identification of data gaps as the basis for recommending effective sampling and analysis strategies and technologies. Optimization focuses on increasing data density, usability and reliability; minimizing project costs through reduced mobilizations and report generation; and supporting the evaluation and selection of remedial alternatives. Techniques such as incremental sampling and three-dimensional (3-D) visualization may be explored in order to obtain more information about contamination at the site.

To see information about optimization for the other pipeline or optimization stages, visit Design stage, Remedy stage or LTMO stage.
The following are sample types of data analyses performed during an investigation stage optimization:
- Identification of various sources of uncertainty and prioritization of addressing those sources of uncertainty
- Interpretation of existing conceptual site model (CSM) and identification of data gaps
- Considerations for CSM refinement
- 3-D visualization and analysis
- Interpretation of characterization data
- Considerations for applying innovative sampling strategies and statistical sampling designs
- Considerations for applying real-time data collection technologies
- Considerations for developing dynamic work plans for characterization
- Considerations for electronic data management
- Considerations for technology selection and demonstration of applicability to the site
- Receptor and pathway data needs, sequencing of proposed activities
