The primary objective of this study was to evaluate the long-term effectiveness of a chitin (crushed crab shells) substrate compared to traditional ligneous (wood chips, hay, and manure) substrates on Zn, other metals (Al, Cu, Fe, Cd, Mn), and sulfate removal in MIW under anaerobic column bioreactor conditions. The secondary objective includes the evaluation of aeration and neutralization water pretreatment on the removal of the mentioned contaminants. This dataset is associated with the following publication: Pinto, P., S. Al-Abed, and J. McKernan. Comparison of the efficiency of chitinous and ligneous substrates in metal and sulfate removal from mining-influenced water. JOURNAL OF ENVIRONMENTAL MANAGEMENT. Elsevier Science Ltd, New York, NY, USA, 227(1): 321-328, (2018).
