16 <br /> 3.1.2 Hydrogeologic Parameters and System Construction Specifications <br /> In addition to the above parameters, the following aquifer parameters and system specifications <br /> were used to calculate the the operational effects of the UVB system <br /> • v (Darcian velocity) = 3 8 x 10"7 msec <br /> • Kh (horizontal hydraulic conductivity) = 3 8x 10-3 crn/sec <br /> • K„ (vertical hydraulic conductivity) = 3 8 x 10'cm/sec <br /> • Horizontal hydraulic gradient = 001 <br />' • H (thickness of treatment zone) = 4 27 m <br /> • at (height of upper screen) = 2 m <br /> • ab (height of lower screen) = 1 22m <br /> • Q (UVB well discharge flow rate) = 2 m3/h <br /> 3.2 CALCULATED OPERATIONAL AFFECTS <br /> 3.2.1 Circulation Cell Capture Zone and Release Zone <br /> e <br /> Based on the above assumptions and parameters, the following upstream and downstream <br /> stagnation point distance S and capture zone widths Bt and Bb have been calculated (Figure 6, <br />' Appendix F) for the proposed UVB system at former Exxon RS 7-3942 <br /> S (stagnation point distance) = 13 8m <br />' • Bt (capture zone top width) = 15 3m <br />' • Bb (capture zone bottom width) =41 lm <br /> • (Bb+Bt)/2 (circulation cell width) = 282m <br />' As shown in Figure b, the proposed UVB well will be installed at the location of existing well <br /> RW-3, which will be overdrilled and converted The location of RW-3 was chosen for the <br /> installation of the UVB well because it is near the center of the plume and is located within the <br /> site boundaries <br />' WP61 73942 WPI096 7X 5 5 <br />
