error of 43 percent is associated with this value. The three stations are then averaged, for a regional deep percolation value of 6.50 inches. Quality of Rainwater Hantzsche and Finnemore listed 1 mg/L-N as the nitrate concentration of rainwater for their original calculation; in the past, Live Oak has also utilized this value for the nitrate loading calculation. In May 2019, Live Oak collected rainwater during two storm events in Lodi; in March and May 2020, Live Oak collected two additional samples at the same location. Each sample was collected in a clean, dry, stainless steel bowl, then decanted into a plastic container and placed on ice for transport. The samples were analyzed for nitrate by FGL Environmental of Stockton. Nitrate was detected in the May 17, 2019 sample at a concentration of 0.4 mg/L-N, in the May 19, 2019 sample at a concentration of 0.2 mg/L-N, in the March 16, 2020 sample at a concentration of 0.2 mg/L, and in the May 18, 2020 sample at a concentration of 0.4 mg/L. Live Oak then averaged the concentrations of the four samples, for a value of 0.30 mg/L-N to represent the nitrate concentration of rain. Because the San Joaquin County Environmental Health Department has requested that local and recent data be utilized wherever possible, the concentration of the Lodi rainwater been selected for use in the nitrate loading calculation. Quantity and Quality of Domestic Wastewater The owners of the Site plan to construct a shop building near the new well; it will not have a septic system. There are no other plans to develop the Site, and there are currently no structures on the Site. Based on the assumption of the nitrate loading method that only septic systems should be considered for the calculation, the wastewater flow from the proposed future use of the Site will be zero. Nevertheless, for the purposes of this study, a hypothetical five-bedroom house and three-bedroom second unit dwelling are assumed for each parcel. These are considered so that, should the property owners at some point in the future decide to build on the land, nitrate loading will have been addressed. Crites and Tchobanoglous (1998) list a typical flow rate of 50 to 70 gallons per person per day for an individual residence. In the past, San Joaquin County Environmental Health Department has requested that the flow rate be calculated as 140 gallons per bedroom per day to reflect maximum usage. On March 4, 2020, however, Michael Kith, Registered Environmental Health Specialist, Program Coordinator at the San Joaquin County Environmental Health Department, stated that he has conferred with Norman Hantzsche (author of the 1992 paper discussed previously), and they have arrived at a LOGE 20-29 Page 12
