Therefore, to convert back to ppm, the numerator and denominator must be divided by 2 with the result of 17.8 milligrams NO3-N per 1 x 146 milligrams, or 80 ppm nitrate rise uently, the water table mixing layer will undergo a theoretical dilution eff �m the percola g f ent (reduction from 97 ppm nitrate to 80 ppm nitrate) and create a itrate concentrati less what is currently found in the water table underlying the proposed efflue ' osal area. di on, if the effluent nitrate concentration (61 ppm as nitrate)were to percolate down to t e in ater aquifers (virtually impossible)with a groundwater nitrate coOce n of 7 ppm nitrate, the resultant cone ai would be: 61 ppm+ 7 ppm=68 ppm-2 34 pin nitrate, which is still below the MCL f 45 p nitrate. This effluent recharge nitrate concentration creating a dilution effect within the water table is in compliance with the Porter-Cologne Water Act,which summarily states that there shall be no further degradation to any waters of the State of California. It is imperative that all food and food b - roduct wastes trom the kitchen are handled as solid wastes and not be disposed a into the sg tics stem. This will prevent concentrated or anic loadinrolon the ti es an o the wastewater dis osal system and reduce nitrate loadin potential,- The kitchen sink must not contain a garbgge disosal and oils and rease must not be poured down the sink drain. V. LIMITATIONS The findings, opinions and conclusions of this report are based upon information from standard engineering and analytical test procedures,contemporary scientific literature and agency consultations. Information in this report is deemed reliable by the sources from where it was obtained. Results of the percolation testing should be assumed to only represent the subsurface conditions encountered in the specific area of testing and not of the entire disposal area(s)to serve the new Gurudwara Sahib Tracy Sikh Temple. This report is based upon current scientific knowledge to assess factors which are extremely variable and complex within the environment. Although there are several methods to predict environmental impact from a septic system, San Joaquin County Environmental Health Department Sewage Standards and requirements have been employed for these purposes, and for this project. Therefore,no guarantee or warranty concerning any aspect of this investigation, is expressed or implied. The opportunity to provide this service for you is appreciated.
