13. ABSTRACT (Maximum 200 words)
The Eagle River Flats impact area is a Ft. Richardson Superfund site. It is a salt marsh that is contaminated with
white phosphorus (WP), and remediation of sediments in permanently ponded areas may require dredging. A
remotely piloted dredging system was designed, constructed, and deployed at the Flats as part of the overall site
remediation feasibility study. Experience gained over two years of engineering study and contract operation
indicates that, although feasible and effective, this alternative is slow, difficult, and very expensive.
