Environmental pollution due to industrial activities has been reported since 1760, dating back to the first industrial revolution. One industrial activity that has led to major environmental degradation is coal mining, which can pollute surface and underground water due to acid mine drainage (AMD). Phytoremediation is low-cost, applicable, environmental, and does not generate other waste materials. In this research, we analyze the utilization of Eichhornia crassipes and Pistia stratiotes for AMD treatment. The results indicated that the AMD initially contained Fe, Mn, Al, Ca, and Mg. E. crassipes successfully reduced these contents by up to 69%, while P. stratiotes removed up to 62%. A cost analysis for phytoremediation of AMD is designed in terms of two schemes, with 4298 USD for the first scheme and no cost in the second scheme. The post-harvest potential, future research directions, and bibliometric analysis are also discussed. Overall, the results of this study indicate that P. stratiotes and E. crassipes are plants with great potential for AMD phytoremediation. © 2022 by the authors.
