Reported Results:

Reclamation at the Fleming AML site using FGD product was successful

  1. Vegetation was reestablished and erosion was reduced.
  2. Water quality showed a raised pH, which was maintained throughout the 7-year period after reclamation.
  3. Surface water and ground water quality improved compared to the levels found prior to reclamation.
  4. Because of low application rates and sorption onto iron and aluminum hydroxides, it is believed none of the toxic elements of concern (arsenic, lead, or selenium) will cause water quality problems at these application rates.
  5. Seven years later, however, ground-water quality remained poor and showed no signs of improvement.
