58 <br /> EnvirotacticS <br /> An Earth Systems Company <br /> 3.0 WATER LEVEL MONITORING <br /> Water levels were monitored to document ambient conditions prior to the July 16-17, 2025 drawdown test <br /> within the Rigsbee, Griffin, and Proposed Community Wells between June 13 and 28, 2025.The locations of <br /> the wells are shown on Figure 5 in Attachment 1. Well Sounder 2010 PRO devices, which are manufactured <br /> by Eno Scientific LLC, in Hillsborough, North Carolina,were installed within each of the three wells to monitor <br /> and record the depth to water.Graph 1 below plots the depth-to-water versus date as recorded by the Well <br /> Sounder devices. <br /> Graph 1 -Well Water Levels from June 13-28, 2025 <br /> DatelTfine <br /> ry� a y9 a e 'P ti9 m ry� A ti9 e ti� v, ry@ o 'Y°i m I P m ti� p � <br /> 1ti IV a1 IV sry ti° o� T lb Ir t roti 1� IV a� 1° Q- rp roti ti° % <br /> 3"��nryy''ryory5"Aorym"�rygry ,y61"10oryy" ryv�"bvory11"`1a61"Ij�ry ,yb �yryv"9,ryo�6"%1ryoryy ryy� ,y �, gyy?��ryory� ory�ry�,yryh��ry6ryry6'ryQry dry��ry���Oryy <br /> 0 <br /> za <br /> AM A <br /> 40 <br /> � —Rigsbee Well <br /> ten. <br /> � �GriRin Well <br /> d <br /> 60 —Pra—dC--Ity Well <br /> Cn <br /> d <br /> 80 <br /> 100 <br /> Un <br /> As shown in Graph 1, between June 13 and 28, 2025, the Rigsbee Well static water depth below ground <br /> surface (bgs) ranged from 23.49 to 105.01 feet bgs and averaged 35.01 feet bgs.The depth to water regularly <br /> fluctuated from approximately 23 feet and approximately 45 feet below the surface throughout the <br /> monitoring period, indicating this is the normal variation for the Rigsbee Well. However, there were notable <br /> instances of more significant fluctuations between June 14 and 16, 2025. Between 05:54 and 10:04 on <br /> June 14, the depth to water dropped from 24.43 feet bgs, to 91.23 feet bgs, respectively.After a rapid rise to <br /> 57.08 feet bgs at 15:09 there was another rapid drop to 87.04 feet bgs at 15:54 before again rising rapidly to <br /> 24.49 feet bgs at 06:24 on June 15. Again, on June 15, the water level dropped from 23.76 feet bgs at 07:34, <br /> to 105.01 feet bgs at 15:39 with a small interruption in between. Then, by 06:09 on June 16, it rose again to <br /> 23.82 feet bgs. <br /> Envirotactics, LLC Page 8 of 20 Groundwater Modeling Report <br /> (732) 449-0077 Project No.6704 <br />
