Boring 1 penetrated the alluvial deposits and encountered <br />a sandy lean clay glacial till at a depth of 12'. <br />Fill Mas encountered to a depth of 5' at boring 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 art <br />loose to dense. <br />nixed alluvium was encountered Immediately below the fill at boring 1 and at <br />a depth of 13|' to 15i' 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 of lean clay fine alluvium were encountered from 7|' to 9' at <br />boring 1 and from 151* to 18' at boring 2. The lean clay has a medium con* <br />Ilatency. <br />The glacial till at boring 1 has a rather stiff to stiff conslsttncy. <br />Tbe drainfleld will be cmstructed in the northwest comer of the property, <br />the borings at these locations were classified In accordance with the USOA <br />Soil Textural Classification System, twines A-1.
