<br /> As shown on its Orange County Existing Well/Septic System Authorization, the Rigsbee Well is 505
<br /> feet deep,with a 35-foot well casing and a static water depth of 25 feet. While no formal permit data
<br /> were available for the Griffin Well (i.e., it appears to pre-date the Orange County Database/Permitting
<br /> Requirement), the owner indicated that, to his knowledge, the Griffin Well depth is 75 feet, with the
<br /> pump at 65 feet and the static water depth at 35 feet. As shown in the Yadkin Well Company's report
<br /> (Appendix 1),the Proposed Community Well depth is 665 feet, its static well level is 33 feet below the
<br /> top of the casing and the casing extends 2 feet above the ground surface.
<br /> As shown in Graph 1, between 13 and 27 June 2025 the Rigsbee Well static water depth below the
<br /> surface ranged from 23.49 to 105.01 and averaged 35.01. The depth to water regularly fluctuated
<br /> from approximately 23 feet and approximately 45 feet below the surface throughout the monitoring
<br /> period, indicating this is the well's normal variation. However, there were notable, more significant
<br /> fluctuations between 14 and 16 June 2025. On 14 June, between 0554 and 1004,the depth to water
<br /> dropped from 24.43 feet below the surface,to 91.23 feet. After a rapid rise to 57.08 feet at 1509 there
<br /> was another rapid drop to 87.04 feet at 1554, before again rising rapidly to 24.49 at 0624 on 15 June.
<br /> Again, on 15 June the water surface elevation dropped from 23.76 feet below the surface at 0734,to
<br /> 105.01 feet at 1539, with a small recovery in between.Then, by 0609 on 16 June,the depth to water
<br /> rose again to 23.82 feet. Although the Rigsbee Well exhibited a normal variation in depth to water of
<br /> approximately 22 feet, the monitoring documented that under "ordinary use" the depth to water
<br /> occasionally fluctuated more dramatically. The magnitude of these transient fluctuations were up to
<br /> about four times that of the routine variation.
