Shannon & Wilson, Inc. (S&W), uses a soil GRAIN SIZE DEFINITION <br /> classification system modified from the Unified DESCRIPTION SIEVE NUMBER AND/OR SIZE <br /> Soil Classification System (USCS). Elements of <br /> the USCS and other definitions are provided on FINES <#200(0.08 mm) <br /> this and the following page. Soil descriptions <br /> are based on visual-manual procedures(ASTM SAND' <br /> D 2488-93) unless otherwise noted.
