December 18,2001 <br /> _ Job Number: LGO1-375 <br /> Page I 1 <br /> N (2.69 mg/L as NO3). The Environmental Protection Agency maximum contaminate level for <br /> drinking water for nitrate and nitrate as nitrogen is 45 mg/L-NO3 and 10 mg/L-N respectfully. <br /> No DBCP was found in the ground water. <br /> The nitrate loading analysis has shown that the use of a"typical" septic system will not <br /> cause a build up of nitrogen in the shallow aquifer above the maximum contaminate level of 10 <br /> mg/L-N for the proposed project with the stated occupancy and assumptions. <br /> Based on the results of this study, the project is suitable for the proposed development. <br /> The recommendations for the project are as follows: <br /> 1) Follow the San Joaquin County Public Health Services Sewage Standards where <br /> applicable for design of the septic system. <br /> 2) If large gatherings or special events are to occur on the site, the use of portable <br /> chemical toilets is recommended. <br /> _ 3) Any occupancy changes should be brought to our attention so our calculations and <br /> recommendations can be amended. <br /> IX. LIMITATIONS <br /> The conclusions of this report are based on the information provided regarding the <br /> existing and proposed development, the use of the subject property, and the site conditions as <br /> they existed at the time we excavated our test holes and performed the percolation tests. It was <br /> assumed that the test holes and percolation test results are representative of the subsurface <br /> conditions in the general area. <br /> 'pERSO� <br /> Z <br /> �SSpG♦ <br />
