Groundwater Monitoring Well Construction Workplan <br /> August 2023 <br /> Vertical Gradient <br /> Figure 7 provides a graphic representation of the vertical groundwater gradients (heads) between <br /> the Upper and Lower aquifers in Fall 2019,just after high groundwater use in the summer <br /> months, when the difference in groundwater levels are typically the greatest. There is a <br /> downward head between the Upper and Lower aquifers at the drill site. <br /> Head Direction <br /> A T Down(greater than 0.S) <br /> - <br /> r No Change(less than+1-0.3) <br /> :tip ,.., r am.., . t•r ♦ up(greater than OS) <br /> Rkmvt� rl.,_r `,, Unknown (Monitoring Wells not <br /> present Upper and Lower <br /> ,;c <br /> ,trr:' e,. 1�4-E:•,,,i.�s1r ��• S Pr in PP <br /> r: r ` +� �^ Aquifers to allow comparison) <br /> Ll <br /> •! :� , ' I_ County Boundary <br /> I' '�ia 3r�i �' �.� L' MTracy Subbasin <br /> I <br /> A I 1;,.ser Rt s�f A�rf! -,—_- <br /> lurte, iytar-..�- t:}s y <br /> ..Its Tray i <br /> c�$ 01N04E32EO01M' a� <br /> 14t1o..' t,ltrxJ { 01N04E3M-b03M <br /> h,1-1, �qtt =� 01 N 04E36QO02M <br /> G7u2arl �rG� _ <br /> Court Fore bay <br /> „• �L I.Zrr' M506E23 •'003M <br /> 01SO4E28FO03M Ado r 01 06E26K001M <br /> 01 SOdE $FOOAM ._0j Sb6rE29R001 M <br /> 1504E28P002M . <br /> 4E28F001M ! l ! cidental Wells <br /> �X01 SO4E28P003M j' 0150y5�aE33R 02' ','«y_, <br /> 01 SO4E31Pgb5M, ( 'a <br /> 02S03EO1D 1M I [_:,02S05E086001 <br /> � %-- •. � i-36:95). `<� 'fir;. _ ' •- - <br /> MW-6C <br /> rf 02504E15R001 02505 13N0C1`�� <br /> 0 11 MW 58 c <br /> MW-1A <br /> -MW=1B'D MW'5A�'"'": sosE27E001 gt <br /> — —' y !4 <br /> MW-4A x! <br /> MW-2A � <br /> Z, 0350b'E03F002 R <br /> � a MW 3G t ! <br /> ` II�. <br /> MW-3A 1 03S06E05rR, 01M <br /> f r q'', 5 � 191. 4 '� <br /> try Cr Corr I NIW-G Corral MW-203 <br /> Corral MW-7 _03SO6E23•001 <br /> a Corral M <br /> Y I O82j � �' g <br /> j L E2s 001M 0AO6E28F003M <br /> 9p J° f 3506MN001M <br /> ` <br /> 0 3 8 12 N` <br /> m <br /> Miles <br /> Figure 7: Vertical Gradients Between Upper and Lower Aquifers <br /> GEI Consultants, Inc. 14 <br />
