opinion that groundwater next to the pond is roughly at the same elevation as the bottom of the <br /> pond. This groundwater is in equilibrium with the atmospheric pressure exerted on the pond <br /> surface. If the pond were liberating great quantities of water, it would have drained in a short <br /> period of time, which has not been the case. The "heavy" soil structure of the vadose and <br /> phreatic zones, which lower the hydraulic conductivity and transmissibility, is probably <br /> preventing a greater pond water infiltration rate into the surrounding groundwater. <br /> Boring 3-South was drilled 100 feet south of the large pond. Clay content test results for the <br /> five feet, vadose and phreatic zones are 24%, 14%, and 29%, respectively, and zero percent <br /> gravel content. Again, the static water level was measured at six feet below grade, which <br /> roughly corresponds with the bottom of the pond. <br /> As referenced earlier, Boring 4-East was drilled by hand to a depth of five feet where the soil <br /> became very stiff and compact. A sample was taken at this depth for hydrometer testing which <br /> indicates a 21% clay content and zero percent gravel content at this depth. <br /> GROUNDWATER ANALYSES <br /> The first analytical investigation of the groundwater was to measure the electrical conductivity, <br /> pH and temperature of Boring 1-North, Boring 2-West, an adjacent irrigation well, and the on- <br /> site domestic well. Additionally, for comparison purposes, these three parameters were <br /> measured from the wastewater in the small pond and large pond. The data are tabulated below: <br /> Parameter Small Pond Large Pond Irrigation Well Domestic Well Boring 1-North Boring 2-West <br /> Ec 11250 9830 2620 2280 2390 4410 <br /> pH 6.79 8.30 9.42 9.36 9.32 10.12 <br /> Temp.°F 92.6 84.5 72.0 70.5 73.4 76.1 <br /> Tle next groundwater parameters measured were Total Kjeldahl Nitrogen (TKN), Total <br /> Dissolved Solids (TDS) and Nitrate (NO3). These three parameters were measured in the <br /> groundwater from 1.) A domestic well to the west of the ranch, 2.) An on-site domestic well, and <br /> 3.) A domestic well to the east of the ranch. These samples were used for comparison purposes <br /> 3 <br /> ..4' �` l�ulity (Contro1 <br /> l jnspxtion <br /> s `F <br />
