59 <br /> Envirotactics <br /> An Earth Systems Company <br /> Although the Rigsbee Well exhibited a normal variation in depth to water of approximately 22 feet, the <br /> monitoring documented that under "ordinary use" the depth to water occasionally fluctuated more <br /> dramatically. The magnitude of these transient fluctuations was up to about four times that of the normal <br /> variation documented during the monitoring period. <br /> The Griffin Well, on the other hand, showed little change over time between June 13 and 28, 2025 exhibiting <br /> a range in static water depth below ground surface from 34.98 feet bgs to 41.7 feet bgs and an average of <br /> 35.01 feet bgs. Unlike the Rigsbee Well, the Griffin Well exhibited a normal variation of only about 6.75 feet <br /> and transient water level fluctuations documented during the monitoring period were less than about 3 feet <br /> more than the normal variation. <br /> Water level data were also collected in the Rigsbee and Griffin Wells prior to, during, and after the July 16-17, <br /> 2025 drawdown testing of the Proposed Community Well as shown in Graph 2 below. <br /> Graph 2-Well Water Levels from July 7-25, 2025 <br /> Date/Time <br /> e� <br /> 6y� 5ry �hti .5ti �yti a`'ry ti6hry byti ���ayti �6hry pyti ti6yti by7- ti6hti o-yti �6�bym ���pyro �6�a5s tib'yha �.�yye ��.�y`$ h.�y,a �.�gym ���'yyro �,.�yye <br /> ��hrya ryy ryha ryhtiy o�� o�y.Day o�y.o�y o�y.oryy oryy.Q�y oryy.oryy o��.o�y oryy.o�� oryy. y ��.oryy q�y.�y �ryy.o�y gryy)oryy o��.oryy oryy.o�� o�y.° ��tio ��tio��tio ��,yo \tio�ti c1o�`�\1aM1 \ti1ry\ti��'\tiJ�\ti��\1�ti ti°�'\tio��Vti`'��\ti`Dry\ti`�ry\��\ry\�M1\ry\'M1\�\1�ry��ry\1�ry\1�ry fL��ry Qti��ry nary nary�ry t✓���ry fti`�ry�-�ry��ti��ti <br /> M1 '� 1 M1 1 M1 M1 1 1 '1 ' 1 '1 1 M1 1 M1 M1 1 1 1 '1 1 M1 M1 1 1 1 1 1 1 M1 1 1 M1 1 <br /> 0 <br /> 20 <br /> ao Ir F1 I <br /> t -G,fti,Well <br /> a0 <br /> � Well <br /> W PROPOSED COMMUNITYWELL!� <br /> U PUMPTEST PERIOD <br /> oz <br /> 80 <br /> Ul <br /> m <br /> 100 <br /> 10 <br /> Additionally, Graph 3 below presents the response in the Rigsbee and Griffin Well water levels (left axis) <br /> relative to the Proposed Community Well drawdown (right axis). <br /> Envirotactics, LLC Page 9 of 20 Groundwater Modeling Report <br /> (732) 449-0077 Project No.6704 <br />
