The data for the fall quarter are listed below. <br />Well <br />Number Depth to <br />Water (ft <br />from top of <br />casing) pH Temperature <br />Degrees F Conduct- <br />ivity <br />(mmhos) <br />LO-1 6.00 6.5 63 4250 <br />OW-8 41.78 6.0 53 1350 <br />OW-12 dry <br />OW-13 dry <br />OW-14 108 6.5 58 4000 <br />OW-15 dry <br />* The measuring point has been changed on this well due to the <br />installation of a steel protective casing. The new measuring <br />point is approximately 4.2 feet above groundlevel, which was <br />the previous measuring point datum. <br />
