“…AMD are waters with typical high concentrations of dissolved heavy metals and sulfate and can have a pH as low as 2. [1][2][3] When AMD is discharged untreated, it can pollute receiving streams and aquifers, and the resulting overall effect on streams and waterways can be very dramatic. Some of the harmful effects of AMD on the environment include the disappearance of all aquatic life, the coating of river bottoms with layers of rustlike particles, and the decrease in pH of the water and streams.…”

Filtrates were collected using a codisposal reaction wherein fly ash was reacted with acid mine drainage. These codisposal filtrates were then analyzed by X-ray Fluorescence spectrometry for quantitative determination of the SiO 2 and Al 2 O 3 content. Alkaline hydrothermal zeolite synthesis was then applied to the filtrates to convert the fly ash material into zeolites. The zeolites formed under the experimental conditions were faujasite, sodalite, and zeolite A. The use of the fly ash-derived zeolites and a commercial zeolite was explored in wastewater decontamination experiments as it was applied to acid mine drainage in different dosages. The concentrations of Ni, Zn, Cd, As, and Pb metal ions in the treated wastewater were investigated. The results of the treatment of the acid mine drainage with the prepared fly ash zeolites showed that the concentrations of Ni, Zn, Cd, and Hg were decreased as the zeolite dosages of the fly ash zeolite (FAZ1) increased.

“…Effects of AMD from abandoned coal mines on the structure and diversity of stream organisms, such as fish, macroinvertebrates, and diatoms, have been studied extensively (Letterman and Mitsch 1978, DeNicola and Stapleton 2002, Petty et al 2010, Smucker and Vis 2011, but considerably less research has focused on functional aspects, especially of epilithic biofilms. Most research on functional processes has been focused on streams affected by acidification from noncoal-mining sources and has emphasized leaf-litter breakdown (Niyogi et al 2001, Carlisle and Clements 2005, Simon et al 2009).…”

Abstract:This paper presents a model that uses only pH, alkalinity, and temperature to estimate the concentrations of major ions in rivers (Na + , K + , Mg 2+ , Ca 2+ , HCO 3 − , SO 4 2− , Cl − , and NO 3 − )together with the equilibrium concentrations of minor ions and heavy metals (Fe 3+ , Mn 2+ , Cd 2+ , Cu 2+ , Al 3+ , Pb 2+ , and Zn 2+ ). Mining operations have been increasing, which has led to changes in the pollution loads to receiving water systems, meanwhile most developing countries cannot afford water quality monitoring. A possible solution is to implement less resource-demanding monitoring programs, supported by mathematical models that minimize the required sampling and analysis, while still being able to detect water quality changes, thereby allowing implementation of measures to protect the water resources. The present model was developed using existing theories for: (i) carbonate equilibrium; (ii) total alkalinity; (iii) statistics of major ions; (iv) solubility of minerals; and (v) conductivity of salts in water. The model includes two options to estimate the concentrations of major ions: (1) a generalized method, which employs standard values from a world-wide data base; and (2) a customized method, which requires specific baseline data for the river of interest. The model was tested using data from four monitoring stations in Swedish rivers with satisfactory results.
