This data <br /> illustrates a relatively high potential for there to be significant evapotranspiration (or bare soil surface <br /> 1 around the edges of the mound. In <br /> evaporation}from the mound system disposal area,particularly g <br /> { addition,the Delta is well-known for its hot, windy conditions during the spring and summer months, <br /> which will significantly aid in evaporation/evapotranspiration from the mound system. <br /> III. NITRATE LOADING STUDY FINDINGS <br /> The Nitrate Loading Study findings will be discussed in the following sequential categories: <br /> 1.) Projected wastewater flow volumes from the Bullfrog Landing Marina facility. <br /> 2.) Anticipated wastewater characteristics from the Bullfrog Landing Marina facility. <br /> 3.) Calculated Nitrate loading to the groundwater underlying the land-side property. <br /> 4.) Design Criteria. <br /> 5.) The Conclusions and Recommendations Section. <br /> A. WASTEWATER FLOW PROJECTIONS AND CHARACTERISTICS <br /> WASTEWATER FLOW VOLUME PROJECTIONS <br /> A number of variables are involved in estimating wastewater jAverage Daily Flo s(ADF)'from the <br /> Bullfrog Landing Marina. Wastewater flow volume projections for facilities in unsewered areas of <br /> San Joaquin County have been historically and typically calculated under one or more of the <br /> following guidelines: <br /> 1. Data published in the San Joaquin County Sewage Standards. <br /> 2. Data published in the scientific literature. <br /> 3.(Number of:bathro6m fixtures fora facility, leading to calculated flushes per capita. <br /> 4.
