Lab No. 32147 <br /> -2- <br /> Included <br /> 2-Included is the data from an experiimnt we ran to explain the low NO3 values. <br /> Each sample was spiked with enough NO3 to raise its NO3 level 89 mg/L. <br /> The samples were left in close jars at room temperature for 3 days. <br /> At the end of that tire, the sarples were analyzed to determine the NO3 <br /> i� concentration. <br /> In addition, I ran TYN tests on the original samples and the final spiked <br /> samples after 3 days to determine if any of the NO3 had been converted to <br /> NH3 or Organic N. (only samples -1, -2 were run) <br /> Sanple 3 did not exhibit NO3 decrease different from the control. Since this <br /> was the only sample that did[ not exhibit a strong "septic odor" it can be <br /> surmised that some unknown factor rendered any organisms present incapable of <br /> NO3 utilization. <br /> 1 <br /> Conclusions 1403 is being both destroyed and: incorporated into septic biamass. <br /> Together this would probably account for low NO3 levels in septic samples given <br /> 1 significant NO3 inputs. <br /> * = Less Th6n <br /> If there are questions, please call or write. <br /> very truly yours, <br /> Q inn,' Ph.D. <br /> Laboratory Director <br /> J'Q:jgd <br /> F. <br /> t. <br /> r <br /> If <br />�k <br />
