CONCLUSIONS AND RECOMMENDATIONS <br /> Based on this Soil Suitability and Nitrate Loading Study, AGI concludes the following: <br /> • The percolation rate meets the minimum EHD standards in the proposed septic <br /> system disposal field. <br /> • The nitrogen loading rate is above the desired value of 10 ppm. <br /> • Nitrates were detected below the State of California Maximum Contaminant Level <br /> in the onsite waterwell; and DBCP was not detected above the laboratory reporting <br /> limit. <br /> • All approved septic system use should follow the EHD Onsite Wastewater <br /> Treatment System Standards. <br /> 13.0. LIMITATIONS <br /> Our professional services were performed using that degree of care and skill ordinarily <br /> exercised by environmental consultants practicing in this or similar localities. The findings <br /> were based on field testing results. Evaluations of the hydrogeologic conditions at the site <br /> for the purpose of this investigation were made from a limited number of available data <br /> points (i.e., test hole and field data) and subsurface conditions may vary away from these <br /> data points. No other warranty, expressed or implied, is made as to the professional <br /> interpretations, opinions and recommendations contained in this report. <br />
