Quality of Rainwater <br /> Hantzsche and Finnemore listed 1 mg/L-N as the nitrate concentration of rainwater for <br /> their original calculation; in the past, Live Oak has also utilized this value for the nitrate <br /> loading calculation. <br /> To determine a more accurate local value, Live Oak has collected rainwater during 15 <br /> recent storm events in Lodi. Each sample was collected in a clean, dry, stainless steel <br /> bowl, then decanted into a plastic container and placed on ice for transport. The <br /> samples were analyzed for nitrate by FGL Environmental of Stockton. The results of <br /> the rainwater sampling are as follows: <br /> Table 3.
