Groundwater cm be used for <br /> drinking purpose for the proposed uses. <br /> Deep percolation test results and soil strata at 10 feet - 16 feet depth (c ich is silt with <br /> sand) indicates this strata may be used.for septic system. <br /> • Septic system is located on dox%mstream of proposed well, will have no ' pact on septic <br /> System. <br /> + Analysis of water samples collected from faucet of the domestic well on JUlY 121. and 20, <br /> 2010 had low DBCP concentration and little bit higher Nitrates. Agric ltural chemical <br /> applications. diaries, and }vineries in the area may be. the most signifcailt sources of <br /> nitrates into the ground-,vater. <br /> • Existing nitrate level in ground water will not have detrimental effectson health. A <br /> constant pumping of groundwater will eventually reduce this level below o MGL. <br /> n. <br /> • NLS report. groundwater analytical test results. and percolation testing results indicate <br /> site is suitable for the proposed construction. <br /> i No.C 64568d i di –PE 064568 <br /> W.i s <br /> 4 d 'C IV I\1 <br /> �' CAt1F <br />
