The long-term goals of the Fox River Cleanup Project include meeting the following Remedial Action Objectives (RAOs):
The Fox River Cleanup project must meet certain, predetermined goals and measurements. Achievement of the required dredging and capping criteria will be determined by measurements as the work is completed in specified areas.
To determine if dredging is adequate, or if a sand cover will be placed after dredging a specified area, the elevation of the river bottom will be measured and samples of the river bottom will be analyzed and the results compared to the clean up criteria. The thickness of caps will be determined by measuring the elevation of the river bottom and by coring the newly placed cap.
Sampling and surveys will continue following the cleanup, including surface water sampling, sediment sampling and fish tissue sampling as part of the Long Term Monitoring Plan and Operations, Maintenance and Monitoring Plan.
