n (�1 <br /> I <br /> The denitrification potential appears to be a factor due to the fine soil content of the indigenous <br /> soils, the higher soil pH, and high soil moisture content. As referenced, the slowly permeable <br /> stratum found at 15 feet may be causing high moisture content soils above this depth. This was <br /> evident in the drilling procedures whereby high moisture content soils were observed from 10 ft to <br /> 15 ft in depth. This moisture originated from the heavy rainfall experienced during March and <br /> April of 2006. <br /> A careful accounting of the water usage must be done to properly manage any future wastewater <br /> disposal system. Therefore, it is recommended, and will be required by EHD that a flowmeter be <br /> placed in the fresh water supply from the domestic well. Since the wastewater effluent will have to <br /> be pressurized for both drip irrigation and conventional chamber disposal, a flowmeter can be <br /> placed after the effluent pump to record wastewater flow volumes for comparison with domestic <br /> irrigation water use. <br /> iSSS 6�Based-u on_the data__o'btamed=-and the-infomiation- resented- t ism o inion that the Gas <br /> p _ �1?

These systems could consist of septic tanks and conventional,or semi-conventional <br /> effluent disposal methods. This is provided that the C-Store has no food preparation services to <br /> reduce organic loading and consequently nitrate-nitrogen loading. Any additional development <br /> would require a Package Treatment Plant. <br /> i <br /> 1 <br /> I <br /> Page-25- <br /> Chesney Consulting <br />
