Water samples from each well were analyzed for chemical <br /> oxygen demand, total dissolved solids, nitrates, total <br /> nitrogen, pH, and electrical conductivity by appropriate <br /> field and analytical methods. The laboratory results are <br /> summarized in Table 1 . The laboratory data sheets and <br /> chain-of-custody are in included Appendix II. <br /> 2.4 Groundwater Monitoring <br /> The top of each well casing was surveyed by Stephen R. <br /> Thumlert, Registered Land Surveyor #4334, of R.W. Siegfried <br /> and Associates to the nearest 0. 01 foot to allow for com- <br /> parison of water elevations in the wells. The depth to <br /> water was measured with a conductivity probe. The relative <br /> water elevation in each well was computed by subtracting the <br /> depth to water from the elevation at the top of the well <br /> casing. Groundwater monitoring data are summarized in Table <br /> 2. <br /> 2. 5 Infiltrometer Test <br /> A one foot diameter infiltrometer tube was driven into the <br /> soil to a depth of two feet. The soil was presaturated and <br /> the tube filled to a depth of one foot . The water level <br /> drop time was recorded and the infiltration rate calculated <br /> using the following equations: <br /> h = Water drop occurring between each time period <br /> h = TPn-TPn-1 <br /> ET = Time between water drop readings <br /> Timen - Time n-1 <br /> A = Area of infiltrometer tube <br /> I = Infiltration rate <br /> Volume water infiltrated <br /> _ ------------------------ <br /> ET (A) <br /> Three tests were conducted across the site to account for <br /> some spatial variability. Results of the tests are dis- <br /> cussed in section 3. 2 of this report. <br /> 3 <br />
