Page 3 - !120 86-74 <br />typical soil profile at these locations consists of fill and topsoil overlying <br />alluvial deposits. Boring 1 penetrated the alluvial deposits and encountered <br />a sandy lean clay glacial till at a depth of 12'. <br />Fill was encountered to a depth of 5' at borino 1. The silty sand encountered <br />to a depth of 7' at boring 2 is black and very loose. The silty sand could <br />also be fill. A black silty sand topsoil was encountered at the surface of <br />boring 3. <br />The underlying alluvium consists of coarse, mixed and fine alluvium. The <br />coarse alluvium consists of sand with silt and silty sand. These soils are <br />loose to dense. <br />Mixed alluvium was encountered immediately below the fill at boring 1 and at <br />a depth of 131' to 151' at boring 2. The mixed alluvium consists of clayey <br />sand and sandy lean clay. These soils have a soft to medium consistency. <br />Thin layers oT lean clay fine alluvium were encountered from 71' to 9' at <br />boring 1 and from 15j' to 18' at boring 2. The lean clay has a medium con- <br />sistency. <br />The glacial till at boring 1 has a rather stiff to stiff consistency. <br />The drainfield will be constructed in the northwest corner of the property. <br />The borings at these locations were classified in accordance with the USDA <br />Soil "extural Classification System. Borings A-1, A-2 and A-3 indicate the <br />
