Water Pollution Effects: Mining


has several negative and adverse water pollution effects. To know more about these negative effects, please read the following article.

Acid Mine Drainage

When surface or rain water flows over the exposed soil and rock, this may combine with sulfur, that is naturally found, to form sulfuric acid. This acidified water then finally pave its way to ground water and streams. This pollutes the water bodies and causes an havoc in the aquatic life. A few streams can turn so acidic that the aquatic system is destroyed completely. Also, the leaching process may cause heavy metal from the rock and soil to leach out.

Spills and Leaks

Any form of leak in a coal-slurry impoundments or in the waste system of a cyanide leach heap, the result is adverse only. This ultimately results in pollution of ground water, rivers and streams. This also kills the aquatic organisms and causes poisoning of the drinking water.

Mountaintop Removal Mining

In this process, the tops of mountains that are rich in coal are removed. The wastes are then dumped into the nearby valleys. This dumping causes adverse effects such as destroying the stream habitat completely. Also, the living organisms present in that habitat are affected badly.

A Few Facts About Mining

A tailings dam split open in Romania’s Bala Mare mine. Around 20, 000 tons of sludge and 100,00 tons of wastewater mixed with heavy metals, copper and cyanide into the Tisza river. This contaminated wastewater and sludge finally met into Danube which harmed 1,240 tons of fish. Also, for 2.5 million people, the water supply for drinking purposes was polluted.

In the year of 2008, in Tennessee, U.S.A, around 5.4 million cubic yards of coal ash was spilled into the water wys due to failure of an impoundments dam. The marine life was adversely affected, properties were damaged and the drinking water supplies were threatened.
