Project Navigator has worked on the political and technical aspects of major soils, sludges and sediments projects in Louisiana, Texas and California. We have assessed and managed millions of cubic yards of impacted materials in cost-effective programs. We are also expert in communicating our plans and the results of our work to regulators, business owners, and local community stakeholders.

Highlights
- Use of an adaptive management approach rather than a rigid advance selection of "one remedy fits all" approach;
- Use of a net risk reduction analysis taking into account limitations of each approach, including residuals and resuspension from dredging;
- Predicting these limitations and evaluating them as part of the remedy selection process;
- Carefully evaluating environmental site conditions in determining whether those conditions are conducive to dredging as part of the remedy selection process;
- Conducting baseline and post-remedial monitoring as necessary to permit an effective evaluation of the effectiveness of dredging remedies;
- Programmatically, noting that there is a significant need for centralized EPA resources, responsibility and authority at the NATIONAL level, to ensure that these technical considerations are applied, monitored and reported.
