described, sampled, and analyzed for characterization purposes and possible subsequent use as <br />a topsoil substitute if needed. <br />Surface and subsoil horizons (A and B horizons) were sampled to represent no greater than about <br />six inches of soil material per sample. Sub-horizons (B1, B2, etc.), greater than three inches within <br />any major horizon, were separately sampled and analyzed. In the substratum (C horizon), natural <br />horizons (C1, C2, and so forth) were subdivided such that individual samples did not represent <br />greater than about 18 inches of soil material. <br />(Revised June 2008) 2.04.9-9
