  <dc:description>A range of at least one order of magnitude was observed for DTPA-extractable Cd, Cu, Fe, Mn, Ni, Pb and Zn and organic matter content of samples of spoil and cover-soil from eleven western USA surface-coal mines. The observed pH of these samples ranged from 3.9 to 8.9; however, most samples were near-neutral to alkaline in reaction. Most constituent levels were found to be below proposed guidelines for maximum permissible levels in mine soil. -from Authors</dc:description>
