1 <br /> CONCLUSIONS <br /> NLS§ 4.2. The shallow subsurface soils underlying the subject property where the new filter bed <br /> disposal area is to be installed, reveals a clay loam soil structure with acceptable permeability and <br /> a potential high degree of natural denitrification potential at the deeper depths. <br /> NLS§ 4.1. The nitrate loading calculations show the resultant effluent from the single family <br /> residential dwelling will theoretically possess a concentration of approximately 8.7 ppm as nitrate- <br /> nitrogen. <br /> The application rate was determined from the shallow perc rate to be 0.522 gallons/ft2/day. The <br /> total filter bed disposal area will be 1,540 sf of floor area. Therefore, the filter bed can manage: <br /> 0.522 gallons/ft2/day x 1,540 ft2= 804 gpd. <br /> The existing on-site domestic well is non-operational. Therefore, a water sample could not be <br /> retrieved for this report. A new well is planned near the same location as the existing well. <br /> NLS§ 4.2. All decentralized wastewater management systems (septic systems) will eventually <br /> fail. A reasonably long lifespan of the primary OWTS can be expected based on the perc rates <br /> obtained and the incorporated design factors. <br /> Pa«e -8- <br /> Chesney Consulting <br />
