We conducted a preliminary investigation of the soil types present for the <br />,tential location of a wastewater system to serve the existing facility with potential for expansion. For these purposes an <br />mation of a wasteflow of 6000 gallons per day was used. <br />The results of the investigation yielded no area of suitable soils to support such a system. The vast majority of the tract <br />contained soils that are unsuitable for the placement of a subsurface wastewater system due to shallow depths to saprolite, <br />weathered rock, soil wetness, and expansive clay. Only one small area in the extreme Southeast corner would have potential for <br />further investigation to see if enough area exists for a subsurface system. It is estimated that if an area of suitable soil exists in <br />that location, it would not be of significant size and would be on the order of supporting a wasteflow of less than 500 gallons per <br />day. <br />The extreme western portion of the tract was not evaluated due to the required setback from the impoundment and the presence <br />of unsuitable soil. There is a low area across the northern portion that would also rule out the potential for a system. <br />Should you have any questions about our investigation, please feel free to contact me. <br />Jim Brown, RS Pere Burns, RS Alan Clapp, RS, ISS Greg Grimes, RS Tom Konsler, RS David Hecht, RS Ron Hedrick, RS Jan Jackson, RS Wendy Thigpen, RS <br />EH Specialia - EH Specialist Soil Scientist EH Program Specialist EH Supenisor EH Specialist EH Specialist EH Specialist EH Specialist <br />
