The two ponds were constructed extremely well and are denoted as the south <br /> pond and north pond on the attached plot map. It is our undersmnding both ponds will act as <br /> wastewater storage since there will be a mechanical manure separator used instead of a settling pond. <br /> The soil in both ponds were visually and tactually analyzed in the field and in our laboratory in <br /> accordance with ASTM D2488 Practice for Description and Identification of Soils (Visual-Manual <br /> Procedure). The soil throughout the sides and bottoms were extremely homogeneous. Therefore, <br /> the samples from each respective pond was composited for individual testing. Six samples were <br /> taken from the south pond and five from the north pond, at depths of 0-12 inches. The sample <br /> locations are referenced on the attached map, along with the dimensions. The ponds are <br /> approximately 20 feet deep with the bottom elevations near the outside existing grade. <br /> The testing consisted of the hydrometer analysis for _oil samples according to ASTM D422-63 <br /> Particle-size Analysis of Soils. ASTNI D422 specifies the reporting limit for clay size particles as <br /> 0.005 mm or less, and gravel size as 4 mm or greater. <br /> Ou/e.O. and).flan are�Ittffd ae the confidential OroOeny of our clierns for Marti x Any Publication S nereduction at statement],conclusions or enncta from ar <br /> n garalny;ur reoor[s or wle s.s reeerveC,conlln9ent uoon Ule wnflln iYlnoniallOn of Duality ConlrP nsosctlon.Inc_ <br />
