Excerpt from Adding Sodium Hydroxide to Study Metal Removal in a Stream Affected by Acid Mine Drainage In anaerobic wetlands no plant communities are needed to treat amd. Sulfur-reducing microorgan isms reduce sulfate to sulfide and precipitate metals. Because metal sulfides are so insoluble, all but very low levels of metals can be removed from the water. The major disadvantage of using anaerobic wetlands is that amd loading rates must be relatively low to avoid exceeding the rate at which the microorganisms can reduce sulfate. Furthermore, anaerobic wetlands are sensitive to temperature because they depend on growth of microorganism populations. Anaerobic wet lands must be insulated to operate during winter in cold climates, and amd loading rates must be reduced during winter to avoid exceeding the system's capac ity to reduce sulfate.

Methods for restoring native plant communities on acidic mine spoils at high elevations were evaluated in a gbsdemonstration area gcs in the New World Mining District of southern Montana. Research plots installed in 1976 were assessed for 22 years and compared with adjacent native reference plant communities. A 1.5-acre (0.61-ha) area of mine spoils was shaped and treated with hydrated lime, organic matter, and fertilizer. The area was then seeded heavily with five native grasses collected from adjacent native plant communities. Natural seed rain, transplanting, refertilization, and use of introduced species were also studied. During periods of fertilization, biomass and cover were twofold greater than in adjacent native reference communities in some years, but then rapidly declined to levels observed in native reference communities. Natural succession was accelerating within the demonstration area toward formation of a native community with characteristics similar to adjacent reference areas. Soil genesis was progressing and a soil gbsA gcs horizon was developing. Use of native seral species appears necessary for long-term formation of a self-sustaining natural community. Both transplanting and natural seed rain on treated spoils resulted in significantly lower biomass and cover levels than on the seeded area. Our data demonstrate that acidic mine spoils, such as in the New World area, can be treated successfully in-place with lime, organic matter, and fertilizer, and then seeded with a mixture of native seral grasses, followed by surface mulching with erosion blanket. Capping with native soils is unnecessary. Reclamation principles and procedures are summarized.

Marine environment is the largest habitat covering approximately 70% of the total earth surface. Oceans are the main regulatory agent of earth’s climate and harbour a huge diversity of living organisms. Marine environment provide a unique ecological niche to different microbes which play a significant role in nutrient recycling as well as various environmental activities. However with rapid industrialization, urbanisation, ship trafficking and mining activities enormous amounts of waste including heavy metals, hydrocarbons, chemicals, dyes, organic load, agriculture waste, pesticides, antifoulants (e.g. tributyltin) and bacterial pathogens have accumulated in marine/estuarine environments over several decades and pose a serious threat to marine macro and micro biota and humans and therefore require special attention. However some natural marine microbes are known to possess diverse resistance mechanisms and degradation pathways to variety of toxic pollutants and these unique characteristics of marine/estuarine bacteria proved to be an ideal tool in bioremediation of contaminated marine and estuarine environmental sites. Reclamation of marine polluted environments using marine microbes has been found to be effective, affordable and ecofriendly technological solution over conventional physical and chemical methods. Objective of this book is focus on marine pollution and application of marine microorganisms in cost effective and ecofriendly methods of pollution abatement.

Mining activities significantly impact the environment; they generate huge quantities of spoil, promote deforestation and the loss of agricultural production, as well as releasing contaminants that result in the loss of valuable soil resources. These negative impacts are now being recognized and this book shows how corrective action can be taken. The introduction of sustainable mining requires mitigation strategies that start during the mine planning stage and extend to after mineral extraction has ceased, and post-closure activities are being executed. Reclamation of Mine-impacted Land for Ecosystem Recovery covers: methods of rejuvenation of mine wasteland including different practices of physical, chemical and ecological engineering methods; benefits of rejuvenation: stabilization of land surfaces; pollution control; aesthetic improvement; general amenity; plant productivity; and carbon sequestration as well as restoring biodiversity and ecosystem function; best management practices and feasible solutions to the impacts of mining which will reduce the pollution load by reducing the discharge rate and the pollutant concentration; reduce erosion and sedimentation problems, and result in improved abandoned mine lands; and ecosystem development. The authors explain how mining impacts on soil properties and how soil carbon reserves/soil fertility can be restored when mining has ceased. Restoration involves a coordinated approach that recognizes the importance of key soil properties to enable re-vegetation to take place rapidly and ecosystems to be established in a low cost and sustainable way. This book’s unique combination of the methods for reclamation technologies with policies and best practice worldwide will provide the background and the guidance needed by scientists, researchers and engineers engaged in land reclamation, as well as by industry managers.
