GROUND WATER GRADIENT DE7ERMIR N <br /> SITE SURVEY <br /> "rhe survey was conducted by Craig Hyde ( instrument man ) <br /> and Shirley Marshall ( rodman ) . Crain Hyde is a geol°eisvatith <br /> 19 years experience and has been involved in many <br /> 011 <br /> surveys. He recently tool% a course in surveying at Carson <br /> Community College in Carson City. Nv. . in order to sharpen his <br /> Shirley Mar-.hall is a graduate geologist with <br /> surveying s4ciils. <br /> 5 years experience in this type of wor4: and is more than <br /> competent to act as rodman for a survey of this type. <br /> The instrument used was a Topcon Engineer's Level which was <br /> rented from Safe - T - Lite in Modesto. A fiberglass tape was <br /> used to measure di•;tances. The instrument was set up over MW - 4 <br /> and other well-5 wLre shot in in a radial survey. The starting <br /> elevation that was Q51ed was the well collar of MW - 4 which i, <br /> 34.76 ft AMSL. This elevation was established by a previous <br /> consultant on this project. I see no reason to reinvent the <br /> wheel and come off a bench mark on a simple survey such as this. <br /> Doing so would not be a wise use Of our client's funds. <br /> om <br /> is <br /> The other wells on turning� site were <br /> El`rveyed evationsrwerehmeasured to <br /> i tup in <br /> a radial fashion, by <br /> the nearest .01 ft. The actualPpoin��of curvethe On each w ell <br /> collar was marked with a felt tip p <br /> All subsequent water level measurements were measured from the <br /> mark nn each well collar, including those made during the pump <br /> test. <br /> We11 collar elevations follow: <br /> WELL ELEVATICIN <br /> MW - 4 34.76 <br /> MW - v4.24 <br /> - 2 ?4.52 <br /> MW <br /> W - b 54.37 <br /> M <br /> MW - 7 _ X55 <br /> NOTE: A copy of the survey notes are in Appendix C <br /> Collar elevation of MW -- C determined by previous <br /> consultant was .34.29 t 0.05 ft difference ) <br />
