In order to investigate the impact of urbanization and industrialization on surface water quality, a pilot study of Panzhihua () mining town was carried out. The urbanization of Panzhihua region was dominated by industry development and population growth.
Effects of Small-Scale Gold Mining on Surface and Ground Water Quality in the Bogoso/Preastea Mining Area Sampling and analysis of water samples from rivers and boreholes in the Bogoso/ Prestea mining area in the Western Region of Ghana were conducted with the aim of assessing the possible effects of mining on water quality
Nov 13, 2018· Effects of mining - bauxite hydrology Alcoa of Australia mines bauxite for the production of alumina from Western Australia's Darling Range extending from east of Perth to Collie. These operations occur on Mineral Lease 1SA, granted by the State Government under the Alumina Refinery Agreement Act 1961.
Therefore, there is a need to clearly define the point at which adverse mining-related impacts on both groundwater and surface water reach an unacceptable level; that is, the point at which adverse impacts from mining would cause material damage to the hydrologic balance outside the permit area.
The objectives of the Summary of Groundwater Quality Impacts of Uranium Mining and Milling Activities in the Grants Mining District, New Mexico (1975) include:. Assess the impacts of waste discharges from uranium mining and milling on surface waters and ground waters of the Grants Mining …
Mar 31, 2015· Water Pollution from Coal includes negative health and environmental effects from the mining, processing, burning, and waste storage of coal, including acid mine drainage, thermal pollution from coal plants, acid rain, and contamination of groundwater, streams, rivers, and seas from heavy metals, mercury, and other toxins and pollutants found in coal ash, coal sludge, and coal waste.
A hydrologic study was conducted in the area to describe existing hydrologic systems and generalized groundwater quality, to assess potential effects of surface mining on local water resources, and to evaluate the potential for reclamation of those water resources.
Mining is the extraction of minerals and other geological materials of economic value from deposits on the earth. Mining has the potential to have severely adverse effects on the environment including loss of biodiversity, erosion, contamination of surface water, ground water, and soil.
surface reliefs are rocked, and so on. One of the major effects of mining is its impact on ground and surface waters. This, along with other disturbances, make the ecosystem to meet with grevious consequences. The impact of mining on ground water may be considered under the fo11owing areas: a) Lowering of water table b) Subsidence

Coal mining in Appalachia has degraded both the surface and ground water. During mining, ground water is drained from the rocks and the pyrite associated with the coal beds is exposed to air. Oxidation of the pyrite produces high iron ana sulfate concentration and a low p H in the water.
Impacts of underground mining. Underground mining causes huge amounts of waste earth and rock to be brought to the surface – waste that often becomes toxic when it comes into contact with air and water.
This report documents the changes in concentrations of various elements and salts in surface water as a result of surface mining in Colorado. Data has been gathered to show the effect of aging of spoils, changes in ground water quality and effects of various mine practices on surface waters.
Nature of Ground‐water pollution by surface mining Ground water is becoming a major concern with respect to surface mining of coal in both West ia and the nation's other coal fields. Two major concerns are ground‐water quality and ground‐water quantity, but only the quality aspects are addressed in this paper.
6 Draining the life-blood: Groundwater Impacts of Coal Mining in the Galilee Basin from local watercourses and groundwater. This has the potential to cause significant impact on local groundwater dependent ecosystems and fundamentally alter the dynamics of groundwater-surface water interaction.
Land Subsidence: Cause & Effect. ... liquefaction, crustal deformation, subterranean mining, and withdrawal of fluids (groundwater, petroleum, geothermal). ... and thus threatens to damage agricultural and developed lands and degrade water quality in the massive north-to-south water-transfer system.
Water-level and water-quality data were compared with similar data collected during previous investigations conducted during 1976-83 to determine long-term effects of surface mining on the hydrologic system. Before mining, the watersheds were characterized by sequences of flat-lying sedimentary rocks containing two major coal seams and underclays.
A study was conducted over a six-year period in East-Central Ohio to determine the effects of surface mining and reclamation on physical watershed conditions and on ground-water hydrology in three ...
Regulations promulgated from the Surface Mining Control and Reclamation· Act of 1977 require prediction of the probable hydrologic consequences (PHC) of mining as part of the surface mining permit application. The PHC include but are not limited to prediction of ground water levels, quality…

Bacteria and Their Effects on Ground-Water Quality; Bacteria – Contaminant Interactions; ... Watershed Contamination from Hard-Rock Mining — Ground-Water ...
An important consideration in assessing the potential impact of mining on ground-water quality is the natural background quality prior to mining. A detailed discussion of natural ground-water quality and variability is beyond the scope of this report.
The environmental damage caused by surface mining is related to the large amount of surface material that humans remove during mining operations. The environmental effects of surface mining include. Habitat destruction. Soil erosion. Air pollution from dust …
Another effect of sand and gravel mining is the loss of the protection provided by soil as it filters out pollutants (Rutherford et al. 1992; Kalbitz et al. 2000). Removing the organic layer of soil found on the surface of sand and gravel deposits decreases the soil's capacity to absorb contaminants and thus clean water as it passes through ...

Impact of underground coal mining on surface water and ground water quality Sana Akhtar *, Maryam Khalid, Almas Hamid Department of Environmental Sciences, Kinnaird College for Women, Lahore, Pakistan Article published on October 22, 2015 Key words: Underground Coal Mining, Water Quality, Groundwater, Surface Water. Abstract
Recommendations are made on evaluation techniques and control measures. Much of the scientific literature on agricultural impacts on surface and groundwater quality is from developed countries, reflecting broad scientific concern and, in some cases, regulatory attention since the 1970s.
