The following discussion describes the importance and applicability of each physical and <br />chemical test that was completed. Since portions of the overburden will be used as a root growth <br />medium beneath the topsoil, the words soil and overburden are used here interchangeably. <br />REVISED August 2006 <br />2.04.6-18 <br />
