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 below the desired value of 10 ppm. <br />• Nitrates were detected below the State of California Maximum Contaminant Level <br />(MCL) of 10 mg/I in the onsite water well; DBCP was not detected above the <br />laboratory reporting 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 field data and water data) and subsurface conditions may vary away <br />from these data points. No other warranty, expressed or implied, is made as to the <br />professional interpretations, opinions and recommendations contained in this report. <br />
