Trans Sohal Logistics—Nitrate Loading Section Page 12 of 13 <br /> Our Project Number: LGS140011 <br /> October 8,2014 <br /> Table S. <br /> Summary of Nitrate Mass Balance Equation. <br /> Result Average Effluent Leachfield Deep <br /> Parcel (Nc)* Acres(A) Daily Flow Concentration Denitrification Percolation <br /> (mg/L-N) (Q)(gpd) (Nw) (d) of Rainfall <br /> (mg/L-N) (R)(in) <br /> 1 5.8 2.22 38.57 85 15% 3.21 <br /> *Maximum contaminant level(MCL)for nitrate in drinking water is 10 mg/L-N. <br /> 2.3.6 Impact of Nitrate Loading to Nearby Water Sources <br /> Since the subject property is relatively flat, we do not foresee percolating effluent affecting any <br /> surface water resources. <br /> 2.4 Discussion of Nitrate Loading Results <br /> 2.4.1 Total Nitrate Impact <br /> Based on the method and assumptions described, the result of the nitrate loading balance <br /> indicates that the proposed development on the proposed parcel should not cause a buildup of <br /> nitrates in the aquifer above 10 mg/L-N. <br /> 2.4.2 Methods of Mitigation <br /> Because of the favorable result of the nitrate loading calculation, no mitigation measures are <br /> warranted. <br /> 3.0 CONCLUSIONS AND RECOMMENDATIONS <br /> In summary, percolation rates that meet the minimum EHD standards were achieved at depth <br /> (24 feet bgs) in the proposed septic area. The parcel appears suitable for the use of a septic <br /> system designed for the intended usage at depth. All final septic system construction should <br /> follow the San Joaquin County On-Site Wastewater Disposal Standards where applicable. <br /> No groundwater was encountered in any of the borings drilled on the property. No well exists <br /> on the site. No groundwater sample was analyzed. <br /> 4.0 LIMITATIONS <br /> Our professional services were performed, our findings obtained, and our conclusions proposed <br /> in accordance with generally accepted engineering principles and practices.
