Main St., <br /> Stockton,CA. 95202-2708 <br /> RE: 4th Quarter 2011 Septic Tank Monitoring <br /> Commercial Septic Permit #SR0033926 <br /> Dear Mr.Tasiopoulos, <br /> Enclosed please find the most recent analytical results for samplin Masco Family <br /> Olive Company's commercial septic system. <br /> Analytical Results <br /> The TDS ranged from 1,600— 1,630 ppm in the 4th quarter of 2011. TSS ranged 45 - <br /> 63 ppm. The BOD ranged from <65— 136 ppm. Sodium levels remained moderate at <br /> 494- 512 ppm. Nitrate nitrogen was below the detection limit in all three sample <br /> locations with results of<0.1 ppm. Total Kjeldahl Nitrogen ranged from 38-92 ppm. <br /> Total Organic Carbon (TOC) also maintained moderate levels of 19—65 ppm. Please <br /> note that the monitoring requirements request that carbonaceous biological oxygen <br /> demand(C.B.O.D.) be one of the analytical parameters but with approval of EHD,we <br /> have substituted total organic carbon (T.O.C.) for C.B.O.D. Please see the tables on <br /> following pages,which summarizes the analytical results. <br />
