` February 25, 2002 Job Number:LGOl-397 Page 13 The waste water is ultimately disposed of by percolation through the pond bottom and side walls, landscape irrigation, and/or orchard irrigation. The waste water in the pond is used for irrigation on the Chinchiolo Fruit Company site,the Sierra Fruit Packing facility, and/or the orchards west and north of the fruit packing plants. An assumption was made that 20%of the total process waste water generated by both facilities may result in deep percolation below the Chinchiolo Fruit Company property. This assumption is a rough estimate or starting point to determine whether the effect of combining �. process waste with septic waste water has a relative"beneficial'or"negative"effect. The greatest quantities of process water is developed/disposed during the warm summer months where evapotranspiration is the highest. The assumption of 20%deep percolation of process waste water results in a flow of 5,509,487 gallons/year(0.2 x 27,547,434 gallons/year= 5,509,487). A flow of 5,509,487 gallons/year is equivalent to 20,853,408 liters/year. The water quality of the process waste water is tested regularly for TKN,pH,and specific conductance. The TKN test measures the amount of nitrogen in ammonia and organic nitrogen ` in the waste water. The samples are collected by Precision Analytical, Stockton CA. We understand that water quality monitoring of the pond water was required by the California Regional Water Quality Control Board. The water quality reports examined were for the period during cherry production(May 9 to July 10, 2001). The water quality reports were obtained from Chinchiolo Fruit Company. The following table presents a summary of the water quality reports for this period: Table 8. Water quality of waste water during cherry production 2001.
