samples were analyzed for nitrate by FGL Environmental of Stockton. The results of <br />the rainwater sampling are as follows: <br />Table 3. Rainwater Nitrate Concentration <br />Date <br />Nitrate (mg/L-N) <br />5/17/2019 <br />0.4 <br />5/19/2019 <br />0.2 <br />3/16/20 <br />0.2 <br />5/18/20 <br />0.4 <br />1/27/21, 10:00 <br />0 (Non -detect) <br />1/27/21, 19:30 <br />0 (Non -detect) <br />1/29/21 <br />0.2 <br />2/11/21 <br />0 (Non -detect) <br />2/12/21 <br />0.1 <br />10/25/21 <br />0 (Non -detect) <br />12/14/21 <br />0 (Non -detect) <br />Average <br />0.136 <br />Live Oak then averaged the concentrations of the 11 samples, for a value of 0.136 <br />mg/L-N to represent the nitrate concentration of rain. <br />Because the San Joaquin County Environmental Health Department has requested that <br />local and recent data be utilized wherever possible, the concentration of the Lodi <br />rainwater been selected for use in the nitrate loading calculation. <br />Quantity and Quality of Domestic Wastewater <br />Mr. Torres indicated that the existing home on the Site has three bedrooms, and a new <br />bedroom will be added. The proposed ADU will have two bedrooms. <br />Crites and Tchobanoglous (1998) list a typical flow rate of 50 to 70 gallons per person <br />per day for an individual residence. In the past, San Joaquin County Environmental <br />Health Department has requested that the flow rate be calculated as 140 gallons per <br />bedroom per day to reflect maximum usage. On March 4, 2020, however, Michael Kith <br />of the San Joaquin County Environmental Health Department dictated a new procedure <br />LOGE 2213 Page 10 <br />
