4Remediation will be discontinued when the uranium groundwater concentration reaches 119 µg/L, the equivalent of 180 pCi/L as calcuated in Uranium Activity vs. Mass Concentration_Rev. A (07 18).xlsx 5The larger of the following is assumed as initial uranium concentration for estimating the groundwater remediation duration: (1) the maximum representative concentration reported for any well within the remediation area (determined using sampling results for monitoring events conducted from 2011 through Q2 2017), (2) the concentration estimated by conducting incremental averaging of concentrations within the specified treatment area. The incremental averaging is performed using isopleth contours developed using representative groundwater concentrations for monitor wells located within the remediation area (see Iner. AWCA Calcs_Scenario A {10-14-20).xlsx ). Initial aqueous-phase contaminant concentrations will be variable.
6Number of pore volumes assumes linear, reversible and instantaneous sorption, and may result in an underestimation of cleanup timeframe estimates.
7Flow rate is based on the nominal combined groundwater recovery rate for extraction wells GE-WAA-01 through GE-WAA-04.
- Remediation durations presented herein are estimates and do not account for all factors contributing to the actual time required to remediate plumes via groundwater injection and extraction. Estimates will be updated using system performance and groundwater monitoring data collected during the early stages of remedial operations.

7Flow rate is based on the nominal combined groundwater recovery rate for extraction wells GE-BAl-02 through GE-BAl-04.
8rhe total capture area and PV will be larger when wells 1-4 are pumping at 86 gpm and wells 5 & 6 are idle; however, the pore volume used in this calculation is limited to the area exceeding 30 ug/L. Although concentrations in Areas Band C will be below 30 ug/L at the time B3R begins, this is consistent with previous calculations.
- Remediation durations presented herein are estimates and do not account for all factors contributing to the actual time required to remediate plumes via groundwater injection and extraction. Estimates will be updated using system performance and groundwater monitoring data collected during the early stages of remed ial operations.

Calculation of PV for BA 1 are based on 30 ug/L contour lines. The PV used for Area 83R will be larger than value used here, due to increased pumping capacity of wells 1-4 upon discontinuation of Area C3. However, Area 83 PV was used as an estimate, as no areas will exceed 30 ug/L when Area C3 is discontinued.
