V. CONCLUSIONS AND RECOMMENDATIONS SSS§5.4,6.8. The application rate of 0.556 gals/sf/day obtained from the perc rate indicates the indigenous soils can manage the ADF calculated flow of 892 gpd: 0.556 gals/sf/day x (4 sf x 1001f =400 sf x 4 leachlines) = 1,600 sf= 890 gpd. However, soil permeability has no doubt slowed as a result of biomat formation and will eventually slow to system failure. It is noted that all septic systems have a lifespan and as referenced, the time frame to failure of the existing system is unknown and unpredictable, with failure dependant upon numerous factors. From the soil chemistry and physical test results, there appears to be a high degree of denitrification potential within the soils illustrated by a very low concentration at 1ppm nitrate- nitrogen, and of the underlying groundwater_��. s potential is also evident from the well water analysis with a nitrate concentration of 3 ppm nitrate, whlh is only 1 ppm above the detection limit. NLS§ 4.1. The nitrate loading calculations demonstrate loading is eight-tenths of the Maximum Contaminate Level. The area used in the calculations was only the "gross developed area" of 4.13 acres and not the entire parcel of 63.9 acres. Entire parcel areas are typically used in nitrate --- loading calculations since this usually de cribes and delineates the gross developed area for most given projects. It is imperative that all food and food by-product wastes generated from the new Hospitality Room are handled as solid wastes and not be disposed of into the septic system. This will prevent concentrated organic loading, prolong the lifespan of the wastewater disposal system and reduce nitrate loading potential. It is anticipated that a relatively small volume of alcohol from alcoholic drinks will be introduced into the septic tank from this proposed expansion. The scientific literature does not specifically address the introduction of alcohol and its potential adverse affects on septic tank biology that may occur,probably because of such low volumes in relation to other plumbing fixture sources. It is also imperative that all fixtures (toilets, sinks, etc.) are inspected monthly to ensure there is no leakage. Excess water leakage will unnecessarily saturate the leachfield. It is my understanding that Eagal Lakes management brings in portable toilets for larger-than-usual on-site events. This certainly relieves pressure on the conventional septic system, lowers nitrate ) loading, and adds to system longevity. Chesney Consulting
