“…Acid mine lakes form from mine wastes having high acidity, typically caused by high concentrations of sulfate and toxic metals. They create an environmental threat through degradation and diminishing of surface water, groundwater, soil quality, and food quality, and may kill fish, flora, and most organisms in the local waters and soils [33][34][35][36].…”

“…This process is characterized by a sudden flush of built-up oxidation products during the annual thaw . Likewise, arid regions undergo a similar flush phenomenon after dry periods when internal flow wanes (Anawar, 2013). Solute accumulation during dry periods with a high solute release following the initiation of flow is considered analogous to the cycling observed during freeze-thaw phenomena.…”

“…Climate change directly influences hydrology, contaminant generation from mining waste and transport in aquatic ecosystems (Nordstrom, 2009;Anawar, 2013). The transport and fate of contaminants in water, soil and sediment environments can be understood using knowledge of isotopic tracer and reactive transport modeling.…”

“…Many reactive transport models have been developed to interpret the oxygen diffusion in the soil/mining waste, kinetic pyrite oxidation, AMD generation, advectiveedispersive transport of the aqueous components, mineralewater reactions, chemical equilibrium, geochemical reactions, acid neutralization in the spoil pile, water quality and post-mining environmental impacts (Gerke et al, 1998;Kruse and Younger, 2009;Anawar, 2013). As for example, PHREEQC is a geochemical equilibrium model that can determine aqueous chemical speciation, mineral saturation and other above mentioned activities (Eary et al, 2003).…”
