Scope of Work:
- GWTF Remedial Action-Operation (RA-O)
- GWTF Long-term Operations/Long-term Maintenance (LTO/LTM)
Brice is performing Remedial Action – Operation (RA-O) of the Groundwater Treatment Facility (GWTF) and groundwater monitoring at the Cornhusker Army Ammunition Plant (CHAAP) in Grand Island, Nebraska. The project includes long-term operations (LTO), maintenance of a GWTF at Operable Unit 1 (OU-1), and long-term monitoring (LTM) at OU-1 and OU-3. To date, we have successfully maintained operational status of 95%.
One extraction well is being operated at approximately 300 gallons per minute to prevent downgradient migration of contaminated groundwater. The contaminated groundwater is transported to the GWTF to a feed tank upstream of a two-stage granular activated carbon (GAC) treatment train inside the GWTF. Effluent from the GWTF is discharged to a nearby canal.
To execute the work, Brice coordinates with local farmers and commercial facility to gain site access. In addition, because we are working alongside city streets to perform sampling, we have implemented enhanced safety measures. To date, we completed the work with no safety incidents.
