The Effects Of Coal Ash On The Health Of Water Systems

When asked to think of coal mining, what comes to mind? A mountain with a hole cut into the side of it with a set of railroad tracks disappearing into it? Maybe an old mine car or two full of some rocks or coal, with a pickaxe and shovel leaning against it. A few guys with hard hats covered in a black powder coming walking out of the mine pushing a car or two full of coal. The technology has advanced but the process is basically still the same as well as the outcome. Coal is retrieved from underground and taken to factories to be burnt to create electricity or to fuel the steel mills.

Coal is the dirtiest of all fossil fuels. When burned, it produces emissions that contribute to global warming, create acid rain and pollute water. With all of the talk surrounding nuclear energy, hydropower and biofuels, you might be forgiven for thinking that grimy coal is finally on its way out. On the other hand, coal is no sooty remnant of the Industrial Revolution - it generates half of the electricity in the United States and will likely continue to do so as long as it's cheap and plentiful . Clean coal technology seeks to reduce harsh environmental effects by using multiple technologies to clean. Coal is a fossil fuel composed primarily of carbons and hydrocarbons. Its ingredients help make plastics, tar and fertilizers. A coal derivative, a solidified carbon called coke, melts iron ore and reduces it to create steel. But most coal - 92 percent of the U.S. supply - goes into power production .Electric companies and businesses with power plants burn coal to make the steam that turns turbines and generates electricity. When coal burns, it releases carbon dioxide and other emissions in flue gas, the billowing clouds you see pouring out of smoke stacks. Some clean coal technologies purify the coal before it burns. One type of coal preparation, coal washing, removes unwanted minerals by mixing crushed coal with a liquid and allowing the impurities to separate and settle. Other systems control the coal burn to minimize emissions of sulfur dioxide, nitrogen oxides and

Fossil Fuels are extremely harmful to the environment, especially in the ways the fuel is obtained, such as mining or hydraulic fracturing. Coal, a commonly used fossil fuel, can be obtained by strip mining, mountaintop mining, or underground mining (“Coal Explained”). Strip mining has disastrous effects on the environment because of the destructive nature of the process, which removes all soil, rock, trees, and plants above coal deposits. The runoff from this pollutes streams and rivers nearby, which can harm aquatic life and disfigure the body of water,

Clean coal technology usually addresses atmospheric problems resulting from burning coal. Historically, the primary focus was on sulfur dioxide and particulates, since it is the most important gas in the causation of acid rain. More recent focus has been on carbon dioxide (due to its impact on global warming) as well as other pollutants. Concerns exist regarding the economic viability of these technologies and the timeframe of delivery, potentially high hidden economic costs in terms of social and environmental damage, and the costs and viability of disposing of removed carbon and other toxic matter. More, the byproducts of coal power production range from fly ash sludge ponds full of mercury, arsenic, and sulfur in unlined ponds that can leak into the water supply.

Water is probably the most important resource we as people have. Humans can survive without food for several weeks, but without water we would die in less than a week. On a slightly less dramatic note, millions of liters of water are needed every day worldwide for washing, irrigating crops, and cooling industrial processes, not to mention leisure industries such as swimming pools and water-sports centers. Despite our dependence on water, we use it as a dumping ground for all sorts of waste, and do very little to protect the water supplies we have.

I would have to say that from the reading that it can be very harmful for the coal mining chemicals to seep into the ground into our drinking water.

Coal ash also contains selenium which is already needed in our body, but excess amounts can lead to impaired vision, paralysis, and even death. The ash contains a lot of lead, exposure to lead can cause numerous issues in your brain affecting your nervous system and can cause brain swelling. Arsenic which is found in the ash can be harmful, if ingested it can lead to nervous system damage and cardiovascular issues. If arsenic that is found in the ash is absorbed through the skin can cause skin cancer. Coal ash contain boron also can cause damage to the intestines and even death. The EPA is responsible for protecting the environment from these types of spills, but in the case of properly disposing the ash the EPA ruled that coal ash was classified as a non-hazardous material leaving it up to the companies to dispose of it as they want

Things like mining too far into a wall that connects to an older mine, thus increasing the danger of a collapse, is common. Other practices include shoddy dams that contain the slurry, a mixture of water and fine particles of coal, which do not always meet structural regulations that can and have broken and flood nearby communities (Light and Light, 2006). There are other environmental issues that are associated with coal mining. Acid mine drainage is the result of sulfide minerals being exposed to oxygen. This produces sulfuric acid and can dissolve heavy metals from the waste rock, making it bioavailable. Without proper treatment, this will poison the water systems near that mine and will seep into the streams, creeks, and even ground and well water. The water turns orange and is impossible for anything to live off of the water or in it (Kirsch, 2014). Another issue of coal mining is airborne coal dust, which can result in Black Lung disease. This is caused by inhaling too much coal dust and is common in miners, but with surface mining becoming more prevalent, more coal dust is being released into the air and drifting down to the communities. More children and elderly people are having respiratory problems that many believe are because of

Additionally, the Environmental Protection Agency (EPA) published a response update to assess potential impacts to human and aquatic life (2014). The method the EPA employed was to analyze surface water and sediments for contaminants and compare those results to its screening levels. To assess impact to human health, the EPA compared the sediment data to health risk screening levels and compared drinking water samples to Maximum Contaminant Levels (MCLs) as well as to other indicators. Overall, the EPA found those levels found in sediment data and water samples to not exceed human health screening levels and thus determined that there wasn’t significant risk to human health, although the EPA did recommend that people do not come in direct contact with coal ash as it could still pose health risks. These findings were consistent with that of Dr. Shea.

The main pollutant of surface water in the mid-Atlantic region is Acid Mine Drainage, AMD, also called Abandoned Mine Drainage. AMD is a nonpoint source pollution that has degraded more than 4,500 stream miles, in just the mid-Atlantic region, due to the drainage of metal-rich water from mining activities (Jacobs). The runoff is extremely acidic due to the exposure of pyrite containing rocks, a sulfur bearing mineral (FeS2), during mining activities, and the chemical reactions associated with the contact of air and water with such rocks. As a result of such chemical reactions, sulfuric acid (H2SO4) is produced. Several chemical reactions take place and are as follows:

According to the Appalachian Voices Organization, The U.S. Environmental Protection Agency notes that iron and manganese concentrations surpass drinking water guidelines in at least 40% of wells on the Appalachian Plateau, and in about 70% of the wells near reclaimed surface coal mines of the region.This proves that many communities local drinking water are being poisoned by the chemicals and waste left behind from the mountaintop removal sites that has entered their water supply and many water streams. Coal slurry, a waste left after washing and processing coal with water and chemicals, also gets into to their drinking supply and extremely dangerous because it is highly toxic and it can leach into groundwater. Furthermore, “On August 20, 2004, a bulldozer pushed a boulder weighing half a ton from a mountaintop removal site in Appalachia, Virginia. The falling boulder crashed into the side of a residence, crushing 3 year-old Jeremy Davidson in his sleep.” This demonstrates that mountaintop removal is terribly dangerous most especially to local communities affected by it because the debris and explosions from mountaintop removal can destroy nearby buildings and potentially kill someone. Mountaintop removal should be banned because it is a threat to many local

Mountaintop removal and valley filling is the long time process of mining for coal, primarily in southern Appalachia. In mountaintop removal the tops of mountains are removed to expose the layer of coal. The earth that is removed from the mountaintop is then disposed in nearby valleys. Following the removal of the coal from the mountain, the coal is “washed”; the liquid that is left over after cleaning the coal is called coal slurry. This process of reshaping mountains and valleys has dangerous and everlasting effects on the ecology and aesthetic value of the mountain. Citizens in rural Appalachia typically rely on water from small streams in order to have a clean water supply for their families. Due to the misshapen landscape caused by mountaintop removal and runoff from coal slurries, communities surrounding mountaintop removal sites and valley fill typically experience contaminated water. Even though mountaintop removal coal mining is an effective way to remove the entire amount of coal from a mountain, mountain top removal should be strictly regulated by the government because the water quality of persons in areas surrounding removal sites are being demolished and flow rates of streams and stream ecosystems are being disturbed due to the nature of mountain top removal and valley filling. To begin, it is important to discuss the rights water uses have in areas surrounding mountain top removal sites as well as the trade-offs water uses make in dealing with large coal

Proper, sustainable disposal methods of coal ash or fly ash proposed by the scientific community include the recycled use of this byproduct from coal-burning energy plants and the transfer of current coal ash ponds unequipped with the proper monitoring equipment to be transferred to a certified location where it can be stored and accessed for future recycling attempts. To be properly equipped the site must contain the following: synthetic bedding liners, leachate collection systems and ground water monitoring. These systems and this solution have been proven to reduce the environmental threat these facilities impose onto the environment; proven to improve the environment by reducing greenhouse emissions with the replacement of coal ash for

Coal, a mineral I have discussed previously, is necessary to our everyday lives. Coal is an incredible source of energy; it heats our houses and buildings, and also fuels stoves. You may often wonder where this extremely useful mineral comes from. Coal does not just appear; it needs to be mined through a process which results in our being able to utilize it. Coal mining is fairly inexpensive, is carried out on a large scale and can be mined in either underground or surface mines.

Few resources are essential to human survival. Access to clean water is the most critical of all. Water is a vital resource responsible for sustaining all life on earth. However, clean water is in short supply, but in high demand in all parts of the world. It is thought that most Americans have access to safe, affordable, clean water right from their taps. However, the media is uncovering the true nature of America’s deteriorating water situation. Americans have reason to be seriously concerned about the state of their drinking water. So what really is on tap in America?
