CONTROL OF ADVERSE EFFECTS OF COAL SURFACE MINING ON GROUND WATER QUALITY All three phases of coal surface mining--pre-mining exploration, active mining, and post-mining reclamation--can potentially have negative impacts on ground water quality.
Toxicology indices of metals present in industrial discharges were used as an additional tool to assess water quality, and the newly proposed environmental water quality index (EWQI) lead to better trend in the impact of coal and coal seam gas mining activities on surface water quality when compared to the upstream reference water samples.
The groundwater from the mines is more acidic than surface waters and disrupts ecosystems by changing the pH conditions of soil and water sources. Subsurface mining operations don't create the visible changes in the landscape that surface mining operations do, but the conditions of subsurface mines are extremely hazardous for the working miners.
has the effect of temporarily lowering the water level in a pit pond (imagine removing a rock from a bucket of water). The water surface in very large below-water pit ponds will stabilize at a uniform level, whereas the groundwater table before extraction may have been irregular or sloping. Therefore, the water table around
Much anecdotal evidence is available to indicate that blasting, mining-related subsidence, and acidic drainage can affect ground water, but these effects are generally not well documented, and cause-and-effect relations between mining-related disturbance and degradation of ground-water quality and quantity are poorly understood.
Surface water infiltration recharges groundwater storages, which in turn feed our rivers, wetlands and lakes. Sustainable use of groundwater depends on reliable assessments of the total resource, balancing abstraction with recharge, and ensuring water quality is maintained.

EPA's water quality criterion for selenium provides recommendations to states and tribes authorized to establish water quality standards under the Clean Water Act. This final criterion includes information to help states to develop site specific criteria that account for differing local conditions.
Globally, mining activities have been responsible for the contamination of soils, surface water and groundwater. Following mine closure, a key issue is the management of leachate from waste rock ...
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
Aug 22, 2018· Other effects of coal fires include rising surface temperatures and contamination of groundwater, soil and air. Although coal fires can be caused by thunderstorm lightning, and forest or peat fires, they are often caused by mining accidents and improper mining techniques.
Effects of Surface Mining on Ground Water Quality by Henry Rauch 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 ...

Click here to download the full handbook. Many factors affect the quality of surface and groundwater. Water moving over or under the land surface can undergo physical and chemical
The major potential environmental impacts associated with mining and associated mineral processing operations are related to erosion-prone landscapes, soil and water quality, and air quality. These potential impacts are recognized and addressed in current mining operations as well as in some former mining operations by reclaiming areas of ...
(PDF) IMPACTS OF IRON ORE MINING ON WATER QUALITY AND . The results from the various water quality test conducted revealed that there is a potential of surface and ground water pollution by iron ore mining. Discover the world's research. iron ore mining water pollution MECHINIC Heavy Machinery. Pollution Iron Water.
Surface mining requires groundwater monitoring at many stages. Groundwater monitoring, both sampling for water-quality analysis and measurement of water level, is required for one year on a quarterly basis for the baseline information that is submitted with the initial permit application. ... Groundwater impacts related to the initial and ...
The condition of ground water reflects a combination of physical, biological, and chemical attributes, which are influenced by both natural sources and human activities. Physical properties reflect patterns of flow—the volume, speed, and direction of ground water flow in a given location. Biological contaminants can include bacteria, viruses, protozoans, and other pathogens.
Mar 01, 1982· Open-cast mining operations conducted below groundwater table often affect the drawdown of the water table over large areas which as a consequence changes the natural regional hydrological balance. Remedial measures may include construction of new water intakes, and changes in the land usage may be necessary. Tipping of wastes (most often coal wastes and ashes) affects ground water .
waterbodies and provide high quality water for downstream uses (Yoder et al. 2000, Wallace and Meyer 2001). Although state and federal regulatory requirements to protect water quality exist, impacts to streams due to surface mining are still common and widespread. Surface mining impacts streams
The acid runoff further dissolves heavy metals such as copper, lead, mercury into groundwater or surface water. The rate and degree by which acid-mine drainage proceeds can be increased by the action of certain bacteria. Acidic, metal-laden drainage from abandoned coal mines can have substantial effects on aquatic resources.
matter, as well as other groundwater quality factors. Groundwater pollution works differently from surface water pollution, although they have many sources in common, such as fertilizers, pesticides, and animal wastes. Several important concepts should be kept in mind: 1.Unlike surface water, ground water does not typically flow toward a single
respect to surface and underground mining of coal in many state of our country coal fields. Ground-water quality is being addressed in this review paper. Despite the new emphasis placed on ground water by regulatory authorities, the effects of coal mining on ground water are still poorly understood. It .
Jan 23, 2017· Mining can deplete surface and groundwater supplies. Groundwater withdrawals may damage or destroy streamside habitat many miles from the actual mine site. In Nevada, the driest state in the United States of America, the Humboldt River is being drained to benefit gold mining operations along the Carlin Trend.
Long-term effects of surface coal mining on ground-water levels and quality in two small watersheds in eastern Ohio.
