8.1 - Groundwater Remediation Overview 3

Phase I

Only recover groundwater from areas in which U > DCGL.

Treat only for uranium.

Maintain separate injection for BAt and WA treated water.

Phase I ends when all wells yield uranium < DCGL.

Phase II - dependent on remaining funding

Options - Stop operating, continue with existing systems, or add infrastructure and expand operations.

Operations cease and post-remediation monitoring begins when funding dictates.

Note:

Filtered sediment is delivered with filter backwash to the effluent tank for discharge.
