C. Soil Analytical Chemical Test Results <br /> Soil samples for analytical testing were retrieved from the depths referenced above. The attached <br /> Soil Analysis Report illustrates the test results. Analyzed constituents relating to nitrate loading <br /> include the organic matter content of the soil,pH, Cation Exchanae Capacit�(CEC), and the <br /> tro'en <br /> w contribution of nt g <br /> nitrate-nitrogen content. The organic matter is low, <br /> in 1 <br /> catin a to c <br /> release. The nH is sontewilat acldu„at the surface but alkalii, at the deeper a ths. This alkalingy <br /> appears tp haye influenced nitrification positivel . The CEC indicates the soil potential to retain <br /> alturlonium molecules that are found in septic system effluent. The CEC has a high potential to <br /> inhibit nitrification, and is generally high. Of significance is the nitrate-nitro&en concentrations at <br /> each depth, revealinga high concentration at 5 feet, but significantly decreasing throughout the <br /> deeper depths. This may be attributable to denitrification. The Table below summarizes the <br /> important soil parameters analyzed: <br /> TABLE i <br /> SUMMARY OF SOIL ANALYSIS <br /> xt� <br /> DEPTH OF SAND SILT CLAY SOIL DENSITY USDA/USCS NI'rRATF:N i <br /> SAMPLE % % "/° SOIL TEXTURES CONTENT <br /> ✓ 5 Ft 21'%, 42% 36% 19 Blowx/Ft Cloy 1-00ttJ3llty Lean('Isy 51 ppm <br /> I Stiff Density <br /> 10 Ft+ 2 7 + 43 Blosss'Ft ('loy Loont/SBty Lean Clay 8 ppm <br /> Very Hard Density <br /> 15 FI 39% 36% 21"/u 18 Blows/Ft Loaln/Silt 5 pp'ti <br /> Nledium Densil)' <br /> 20 Ft 25% 56% 18% 8 Islwyn Silt LoandSitt 9 pP'n <br /> Loose Density <br /> III. GROUNDWATER TEST RESULTS <br /> iThe depth to the water table was measured in the exploratory boring to be approximately 22 feet <br /> below existing grade (,fromm lite top_of il�egmbankment). It is evident that groundwater directional <br /> flow is in an east direction - toward the lake- since sand is being excavated from the floor of the <br /> lake, which is drawing groundwater into the lake. Groundwater flow under the embankment, <br /> which can be considered a dam, is complex and can best be described by flow nets which depict <br /> flow under the weight of the embankment. <br /> It is our understanding that the water source for the toilet will come from the Brown Sand Office <br /> well, which is on the same parcel as the subject business. Consequently, this domestic water <br /> supply was tested for analysis, with the results discussed below. Bottled drinking water will be <br /> provided in the office. Hand washing will consist of"waterless" hand cleaners that are both <br /> antibiotic and fofniulated for grease removal (e.g., GoJo Hand Soap). <br /> Page-4- <br /> "-- Chesney Consulting <br />
