CONCLUSIONS AND RECOMMENDATIONS <br /> In conclusion, analysis of the percolation test indicates a percolation rate of <br /> per inch for a depth of-10.5 feet within the proposed leach field area. 'A forty-foot boringfound <br /> no groundwater in the proposed leach field-area. The-estimated total average yearly nitrate <br /> loading concentration for the property is estimated to be 4.82 mg/l=N, about half of the maximum <br /> contaminate level foi the drinking water. <br /> 3Hantzshe N.N Finnemore,E.J. 1991,Predicating Ground-Water-Nitrate-Nitrogen Impacts.
