“…Both Al and Fe are mainly stored in the root zone, but the distribution of Mn is often noticed in the entire plant body. High acidity removal (43 %) and an increase of the pH from 2.9 to 7.1 are also observed inside the aerobic wetlands [47,49]. The efficiency of wetlands in treating AMD depends on factors such as the seasonal variations, the acidity and metal load and the dissolve or soluble metal concentration gradient [40,42,50,51].…”

“…Wetland plants such as T. latifolia, Lemna minor, Nuphar variegatum and Potamogeton epihydrus can remove 29-56 % of the initial Al load [48]. High Mn retention (~76 %) is also demonstrated by plants such as Desmostachya bipinnata [47].

“…Aerobic wetlands are more efficient in removing Fe, Al and Mn in comparison to other metals. The Fe retention rate in aerobic wetlands can vary from 0.13 to 96 % of the initial Fe load [40,42,46,47]. Wetland plants such as T. latifolia, Lemna minor, Nuphar variegatum and Potamogeton epihydrus can remove 29-56 % of the initial Al load [48].…”

Remediation of Acid Mine Drainage-Impacted Water

The formation of acid mine drainage (AMD), a highly acidic and metal-rich solution, is the biggest environmental concern associated with coal and mineral mining. Once produced, AMD can severely impact the surrounding ecosystem due to its acidity, metal toxicity, sedimentation and other deleterious properties. Hence, implementations of effective post-mining management practices are necessary to control AMD pollution. Due to the existence of a number of federal and state regulations, it is necessary for private and government agencies to come up with various AMD treatment and/or control technologies. This review describes some of the widely used AMD remediation technologies in terms of their general working principles, advantages and shortcomings. AMD treatment technologies can be divided into two major categories, namely prevention and remediation. Prevention techniques mainly focus on inhibiting AMD formation reactions by controlling the source. Remediation techniques focus on the treatment of already produced AMD before their discharge into water bodies. Remediation technologies can be further divided into two broad categories: active and passive. Due to high cost and intensive labor requirements for maintenance of active treatment technologies, passive treatments are widely used all over the world. Besides the conventional passive treatment technologies such as constructed wetlands, anaerobic sulfate-reducing bioreactors, anoxic limestone drains, open limestone channels, limestone leach beds and slag leach beds, this paper also describes emerging passive treatment technologies such as phytoremediation. More intensive research is needed to develop an efficient and cost-effective AMD treatment technology, which can sustain persistent and long-term AMD load.

Passive remediation of Acid Mine Drainage (AMD) is a popular technology continuously under development for more than 50 years now. Roles of eukaryotes, the natural residents of AMD and its attenuator are not emphasized adequately. Studies suggest that macrophyte distinctively generate alkalinity through benthic sediments as part of root respiration. Other eukaryotic populations effectively enrich the carbon source for maintaining sulphate reducing bacterial (SRB) populations and act symbiotically. Algae produce anoxic zones for SRB action and help in biogenic alkalinity generation. While studies on algal populations and actions are relatively available those on fungal population are limited. Fungi show capacity to absorb significant amount of metals in their cell wall, or by extra cellular polysaccharide slime. This review examines the roles of these microorganisms and documents their activities in holistic form in the mine water environment. This work discusses the potential areas of likely future research that could enable AMD remediation using active eukaryotes to be made on sound understanding.

“…More than two decades, constructed wetland has become an alternative technology for acid mine drainage (AMD) treatment (Nyquist & Greger, 2003;Sheoran, 2006;Maine et al, 2007). This passive treatment removes contaminants from AMD through complex mechanisms, involving interacting physical, chemical, and biological processes.…”

Aquatic Plants for Acid Mine Drainage Remediation in Simulated Wetland Systems

Aquatic plant is an important component of a constructed wetland system for treating acid mine drainage (AMD).This study was conducted to investigate the remediation effects of planting three aquatic plants species on AMD quality in simulated wetland systems. Simulated wetland systems were constructed using 10-L plastic containers as growth media comprising mixed-organic substrates and aquatic plant species as planting treatments. The treatments involved individual plantings with Fimbristilys hispidula (Vahl) Konth, Mariscus compactus (Retz) Druce, and Typha angustifolia L., and mixed-planting with a combined three-plant species. As the control was the unplanted media. The plants were continuously flooded with very acidic AMD collected from a mine pit in PT Tambang Batubara Bukit Asam, South Sumatra. During the experiment, the acidity (pH), oxidation reduction potential (Eh), and electrical conductivity (EC) of the flooding AMD were measured after 24 hours of the flooding, and then biweekly until the plants entered their reproductive stage. To estimate Fe removed by plants, AMD samples were taken from both planted and unplanted systems for total dissolved Fe analyses. The data revealed some remediation effects of planting aquatic plants on AMD in the wetland treatment systems. The presence of plants in the wetland system appeared to induce oxygen diffusion to surrounding roots, which might result in Fe precipitation on root surface. Although no differences among planting treatments, Fe removals by plants highly correlated (R 2 =0.92) with the production of plant biomass.
