64 <br /> Envirotactics <br /> An Earth Systems Company <br /> For the Proposed Community Well, the hydraulic conductivity from the 2024 and 2025 pump tests was 0.1 <br /> feet/day and the storage coefficient varied from 0.0062 to 0.1137. <br /> 4.4 Well Depth and Separation Considerations <br /> A generalized cross-section was prepared to highlight the differences between the depths of the study <br /> wells. As can be seen in the figure below, the Griffin Well is shallow while the Rigsbee Well is deeper and <br /> closer in depth to the Proposed Community Well. The differences in depths between the Proposed <br /> Community Well and these adjacent single use wells is significant with 160 feet of difference for the Rigsbee <br /> Well (665 feet compared to 505 feet) and 590 feet of difference for Griffin Well (665 feet compared to 75 <br /> feet). Also, as previously discussed and shown on Figure 5 in Attachment 1, the Rigsbee Well is located <br /> approximately 600 feet west/northwest and the Griffin Well is located approximately 660 feet north/ <br /> northeast relative to the Proposed Community Well. <br /> Considering the horizontal separation between the Proposed Community Well and the adjacent single use <br /> wells in addition to the vertical separation discussed above and that vertical hydraulic conductivity is usually <br /> about 10 percent of the horizontal hydraulic conductivity, withdrawal impacts to either of the adjacent wells <br /> from pumping of the Proposed Community Well would not typically be expected. <br /> GENERALIZED CROSS-SECTION <br /> Proposed Residential <br /> Rigsbee Well Community Well Griffin Well <br /> 560 feet amsl <br /> BLC_QLTH <br /> --- --- ------ —460 feet amsl <br /> . - . . - ---- -- -----'-- --- ---- - -- , <br /> ----- <br /> ^'360 feet amsl <br /> -------,---_ p.•_` __----_--------------- -- -------------------------------------------. - . ____ _____ _______ <br /> —260 feet amsl <br /> - --- --- -= ----- ------------- ----------- ------- <br /> -�� <br /> . - . f " 160 feet am <br /> sl= ---------------- <br /> ------------------- ----------- =-------=------------- -------------- 60 feet ams <br /> - - �- -- - 160 feet amsl <br /> ------ - -- . --=------- ------- <br /> "'-260 fee#amsl <br /> Envirotactics, LLC Page 14 of 20 Groundwater Modeling Report <br /> (732) 449-0077 Project No.6704 <br />
