Hydrographically Bolivian Poopó Lake is located in the basin of Desaguadero River and it has over a dozen main tributary rivers and other smaller rivers with lower flow. The mine water discharge from the abandoned and current mining activities polluted these rivers by carrying heavy metals, dissolved and suspended solids which in turn polluted the Poopó Lake which is considered as an important ...

The vulnerability of water bodies to contamination within the neighbourhood of open mine cast environ cannot be overemphasized. Evidence of radioactive trace elements associated with the target minerals in the Plateau State (Nigeria) showed the extent of this vulnerability. In order to address this challenge, the radioactivity levels of water samples from mine ponds, streams, wells, and borehol...

The Certej basin is situated in the North of Deva town, in Apuseni Mountains and was an important nonferrous mining region. In present the mining activities were stopped, but the acid mine drainage is still affecting the underground water quality. Acid Mine Drainage takes place where sulphide-bearing material is exposed to oxygen and water. This drainage water is characterized by low pH, high s...

Sulfide oxidation is a common phenomenon associated with many mined ore bodies and extracted or processed waste. Where the products of these chemical reactions can enter a water body the result is often a reduction in water quality through the increase of acidity, metals and dissolved salts. Due to an attributed lower environmental impact the release of sulfate has received little attention in ...

Mine planning, permitting and operation require reliable water technology in all its aspects: water inflow, water use, water disposal and discharge, and water impact. Mine water evaluations are relied upon by mining companies, mine regulators and the public to determine whether the mine is technically feasible, optimally designed, financially sound, socially acceptable, and environmentally beni...

Jharia coalfield is one of the most important sources of coking coal in India. Coal mining activities in this coalfield have significantly caused mineralisation of surface and ground water; there-by adversely affecting it’s quality and utility. Several trace elements may be present in mine water released from various mining and processing operations. In this paper, an attempt has been made to a...

Predicting post-mining water quality is a key task in managing mine drainage. The most scientifically-defensible approach would be to undertake thermodynamics-based modeling of coupled geochemical and hydrodynamic processes occurring in flooded and partly flooded underground workings. Most models currently in use make the fatal assumption of local equilibrium, or else do not include all importa...

BACKGROUND Pollution due to mining activities could have an important role in health and welfare of people who are living in mining area. When mining operation finishes, environ-ment of mining area can be influenced by related pollution e.g. heavy metals emission to wa-ter resources. The present study was aimed to evaluate Valiloo abandoned arsenic mine ef-fects on drinking water resources qual...

Relevant implementation of the EU Water Framework Directive with regard to mine water pollution of downstream water bodies requires pressure-impact assessment and catchment-scale economic optimisation of abatement measures. However, pressure-impact assessment is bound to be uncertain. This is because mine water pollution is often an unknown combination of pollution loads, from both known mine w...

In the North of Tunisia, Hammam Zriba region represents an important mine activity zone, it is among the most important in the Maghreb . The mine tailings cause the environment degradation, so it had polluted the atmosphere, the soils, the vegetation, the water quality and the ecosystem of the Hammam ouady (Dry River) which is discharged directly in the Miliane River. The Miliane River represen...
