V. CONCLUSIONS <br /> SSS§5A. The soils underlying the proposed filter bed disposal area for the Ripon Church of <br /> Christ show acceptable permeability that can be considered favorable for the long-term. However, <br /> the permeability of th soils will no doubt slow, primarily due to biomat formation. <br /> NLS§ 4.2, SSS§ 6. . From the soil chemistry test results, it appears that there is some <br /> denitrification and inhibitory nitrification potential within the soil profile due to the 12% clay <br /> content,th�,,soil pH and the soil cation exchange capacity. <br /> NLS§ 4.1. By sampling and testing the effluent from another SJC Church and quantifying the <br /> nitrogen constituents, a very accurate Total Kjeldahl Nitrogen(TKN) concentration was determined, <br /> thus increasing the accuracy of the nitrate loading calculations. The calculatednitrate loadin <br /> potential indicates the percolating effluent may have a resultant nitrate-nitrogen concentrati of 3.1 <br /> ppm, which is roughly one of the drinking water Maximum Contaminant Level (MCL). e <br /> percolating effluent will theoretically contribute a dilution effect to the water table and underlying <br /> aquifers where the nitrate concentration was tested at_!4ypm nitrate (19 ppm NO3-N). <br /> SSS§6.�The anticipated maximum Average Daily Flow(ADF) was calculated to be 826"- als on <br /> Sundays. The filter bed area is proposed to be 2,080 ft' and must accept this highest daily flow. The <br /> Application Rate at the soil-effluent interface depth of 36 inches was determined to be 0.800•gals/ft'/ <br /> day. A filter bed basal area of 2,080 82 x 0.800 gals/ftz/day= 1,664 gals/day, approximately double <br /> the highest anticipated ADF. A Long-Term Acceptance Rate (LTAR) of 0.2 gals/f/day gives an <br /> ADF of. 2,080 W x 0.2 gals/ft2/day=416 gals/day, which remains in the realm of a plausible flow <br /> volume. <br /> 10 <br />
