The mining of oil sands in northern Alberta leaves behind large open pits, tailings, and overburden piles in which the surface and subsurface hydrology has been completely disrupted. Extensive reclamation work is required to reconstruct the entire landscape and reestablish the various elements of the hydrologic cycle. Syncrude Canada Ltd. has established a series of small instrumented watershed...

The Forestry Reclamation Approach uses uncompacted, mounded spoils to reforest mined-land and has been successful in hardwood forests in the Appalachian region. A surface coalmine reclamation site in the Pacific Northwest was used to compare the site’s standard reclamation approach (Reference) with a modified version of the Forestry Reclamation Approach (FRA) along with a modified FRA treatment...

The byproducts of flue gas desulfurization (BFGD) are a useful external source of Ca(2+) for the reclamation of sodic soils because they are comparatively cheap, generally available and have high gypsum content. The ion solution composition of sodic soils also plays an important role in the reclamation process. The effect of BFGD on the soluble salts composition and chemical properties of sodic...

BACKGROUND High salinity (1-10% w/v) of tannery wastewater makes it difficult to be treated by conventional biological treatment. Salt tolerant microbes can adapt to these saline conditions and degrade the organics in saline wastewater. RESULTS Four salt tolerant bacterial strains isolated from marine and tannery saline wastewater samples were identified as Pseudomonas aeruginosa, Bacillus fl...

Wastewater treatment and reuse has passed through different development stages with time. This study reviews the most essential changes in water reclamation reuses over millennia, focusing on initial approaches Hellenic world discussing current situation. Based archeological evidence time records, awareness of Greeks regarding land disposal, irrigation, is highlighted. The latter evolved into a...

A large-scale land reclamation project is now being carried out at Penny's Bay, Lantau Island, Hong Kong. The completed reclamation will provide 2.8 km 2 of land for the construction of the new Hong Kong Disneyland and other essential infrastructure developments. The impact of this project on various aspects such as ecology and environment has been widely discussed. This paper studies the chang...

The growth of the world's population increases demand for fresh water, food, energy, and technology, which in turn leads to increasing amount wastewater, produced both by domestic industrial sources. These different wastewaters contain a wide variety organic inorganic compounds can cause tremendous environmental problems if released untreated. Traditional treatment systems are usually expensive...
