Quarterly Monitoring Report- Fourth Quarter 2014 Page 7 <br /> OAK RIDGE WINERY <br /> WKA No. 6364.07 <br /> December 18, 2014 <br /> ' been a "measurably significant" change in the constituents of concern versus background <br /> concentrations in groundwater. <br /> ' The followingresents th <br /> p e results of the statistical analysis using Analysis of Variation (ANOVA) <br /> ' as specified in the referenced section of CCR Title 27. Parametric ANOVA evaluation of the <br /> data was conducted using the Single Factor ANOVA function built into the Microsoft° Excel° <br /> spreadsheet software package. The input data and output results of each evaluation are <br /> ' included in Appendix E. Table E-1 of Appendix E presents the input values and Tables E-2 <br /> through E-9 present the output results from the evaluation. <br /> In general, the parametric ANOVA analysis indicates there are significant differences in the <br /> means of four of the six data sets. The ANOVA evaluation of pH and nitrate indicate there is no <br /> measurably significant variation in the means. It should be noted that the nitrate significance <br /> test is trivial because the input values are based predominantly on one-half the laboratory <br /> reporting limits. Nitrate was not detected at a concentration exceeding its laboratory reporting <br /> limit in each sample analyzed. The table below presents F-critical and F, which when <br /> compared, indicate whether or not significant(non-random) difference in the means of the data <br /> ' exists. <br /> ' NH3 K NO3 pH TKN TDS Log Log [TDS] <br /> [TKN] <br /> Data F-crit 2.65 2.65 2.65 2.65 2.64 2.65 2.64 2.65 <br /> Sets F 17.69 72.26 1.76 1.62 45.73 17.03 204.9 69.02 <br /> Notes: <br /> NH3—Ammonia pH — loci fH+] <br /> K— Potassium TKN —Total Kjeldahl Nitrogen <br /> NO3 - Nitrate TDS —Total Dissolved Solids <br /> ' Where F isreater than F-crit there likely y i s a significant difference in the means. As shown, F <br /> ' is greater than F-crit in six of the eight evaluations. F does not exceed F-crit in two of the data <br /> set evaluations (Nitrate and pH). <br /> Because groundwater constituent concentrations typically are not normally distributed, the data <br /> sets for TKN and TDS were also transformed using logarithm (logia) function and evaluated <br /> ' using ANOVA.
