Arsenic contamination of groundwater Essays

When we talk about sanitation most of the time it’s concerned with the all the possible ways and services for safe and secure removal of human waste and urine. Through the world, the poor sanitation is one the greatest severe issue. Sanitation plays a vital role on the health of individual within every society (WHO). “The term sanitation also has a great emphasis on the safeguard of the hygienic condition through the proper measures for the collection of trash and wastewater dumping ("Sanitation"

lead, arsenic is a metalloid; and in some food source; like rice; the biggest problem. Arsenic is toxic and carcinogenic, it is highly abundant in nature with a mean availability of 5mg/kg soil within earth’s crust (Manvi Singh, 2013). One of the reason arsenic is abundant in the soil and water is because of mining of coal and other metals. Therefore arsenic contamination has a widespread reach, in regards to food consumption it not only contaminates sea-based food, but also land-based. Arsenic by soil

The particular classifications of contamination and sullying are microbiological, eutrophication, compound, suspended solids, strong squanders, warm, radionuclides, and spills. Microbiological squander for the most part comprise of the waste , material discovered I therapeutic waste. Despite the fact that there are particular directions for discarding this waste material, the contamination comes to fruition when those guideline are not being permitted. ("Water: Laws and Executive Orders," 2010).

absolutely toxic. Arsenic is the twentieth most abundant element and the inorganic form is the most toxic in comparison to certain organic compounds like arsenobetaine and arsenocholine which is tolerated better [1, 2]. In India, cases of arsenic toxicity has been reported mainly from West Bengal and also rivers like Ganga, Bramhaputra, etc. [3]. Groundwater contamination by arsenic continues to remain the major source of exposure in the country leading to cases of chronic arsenic toxicity. Projects

extraction of rock and minerals in mines Many problems can occur as a result of mining, including erosion, formation of sinkholes and the contamination of groundwater, soil and surface water. These are all impacts which affect the surrounding environment, though more problems can occur directly in the mines. These include cave-ins, toxic/explosive gas releases, groundwater flooding, subsidy and explosions when coal mining. Erosion in mining is mainly caused by the wearing away of sediment and subsequent

Introduction and country characteristics Bangladesh is situated in South Asia, bordering Myanmar and India and separated by the Siliguri Corridor from Nepal and Bhutan. Its territory is comprised of 580 km of jungle coastline, surrounded by the largest bay in the world – the Bay of Bengal – and the rivers of Mengha, Ganges (Padma) and Brahmaputra (Jamuna). Bangladesh has a tropical monsoon climate, characterized by high temperature, heavy rainfall and extreme humidity. The average annual rainfall

planet's water assets. It could be said, our seas, streams, and other inland waters are being "pressed" by human exercises not so they consume up less space, but rather so their quality is lessened. Poorer water quality means water contamination. We realize that contamination is a human issue in light of the fact that it is a generally late advancement in the planet's history: before the 19th century Modern Transformation, individuals lived all the more in concordance

inhaled an often deadly level of radon gas, which led to the most common cause of death in the mines being lung cancer. Much of the solid waste from the mining process was left in the mine, and leached into the Colorado River. The effects of this contamination are still being felt

organisms, and recreational activities (Gallucci). Coal ash, also known as coal combustion residuals or CCRs, contains hazardous byproducts from power production, including arsenic, lead, mercury, and chromium, that can poison drinking water sources for humans and devastate wildlife habitats (“Coal Ash Basics”). Groundwater contamination has been documented at 13 of North Carolina’s coal-fired power plants (“Energy-Related”). Even after wildlife advocates exposed the damage to aquatic habitats from the

of fracking website, the contaminated water has been related to cases of sensory, respiratory, and neurological damage. Not only does fracking cause damage to our bodies but it also causes damage to the environment. Fracking causes the contamination of groundwater, methane pollution (and impacts climate change), air pollution, waste disposal and many other

Fracking is not a new think it was invent seventy years ago in 1947(“ Thanks To Fracking, Earthquake Hazards In Parts Of Oklahoma Now Comparable To”).For most of those years it has been loosely regulated because people were further worried about what was happening with the coal industry. The fracking fluid starts in a tank then it moves through a pipe into a sand truck. Then the mixture is moved into the blending truck. It moves tough one more machine which is the frac pump that pumps it down into

manganese and more can dissolve into groundwater, and the organic particles have a high concentration on human’s health. On a better note, some can only cause a bad smell or taste. Landfills can also contaminate water through the decomposition process that can release leachate into the water. These come from industrial and hazardous chemicals. They can only leach into the ground but then contaminate water. Sewers and pipelines can cause water contamination because they can break and then therefore

Owing to the large amount of dissolved salts in sea water, it is necessary to purify it before using it for any purpose, be it domestic purposes or drinking. Desalination is the process in which dissolved salts and minerals are removed form sea/ocean water by using various techniques. These techniques have developed over the years. Different techniques have different perks and the best one is chosen according to its energy efficiency. Various changes govern the usage of desalination techniques

generates approximately 100,000 tons of radioactive tailings and nearly one million gallons of liquid waste containing heavy metals and arsenic in addition to radioactivity.(3) These uranium tailings have contaminated rivers and lakes. A new method of uranium mining, known as in-situ leaching, does not produce tailings but it does threaten contamination of groundwater water

The industrial revolution changed the way that people lived in their everyday lives. With mass production, thanks to the assembly line, people were able to make and consume products at a much faster rate than ever before in history. However, there was a downside to this shift in living. This downside manifested itself in the form of waste. This waste could come in many shapes, colors, smells, and toxicity, but regardless it soon became a problem that has persisted to this very day. People who are

of toxicity one cannot call it toxic until the final analysis comes in (XXX). An attorney with the Southern Environmental Law Center called the statement irresponsible and stated that coal fly ash slurry contains concentrated amounts of mercury, arsenic, and benzene. Local residents and environmental groups expressed concern that the fly ash slurry could become more dangerous once it dries out. On January 1, 2009, the TVA disseminated a fact sheet stating that the ash is not hazardous. Due to pressure

Cadmium is present on the earth’s crust as heavy metal and its exposure in the environment is a very big challenge to environmentalist because cadmium is non-degradable in nature. In environment cadmium transfers from one trophic level to another and finally accumulated in human with toxic effects. There is an emerging need to remove the cadmium from the environment. Microbes are very helpful in this area to remediate the cadmium from the environment. Microorganisms used biotransformation and adsorption

Mining is a practice that has been used for almost all of human history to extract minerals and resources from within the earth. This is the same for on the Australian continent. Aboriginals used mining throughout their 40,000 year history to gather different minerals which they used for tools, as well as for art and religious practices [1]. When European settlers arrived in Australia, mining was set up in the early days. With the first coal mine opening in the region now known as Newcastle within

Did you know that coal was formed 300 million years ago when the world was first being formed? It is considered a non- renewable energy source due to taking one million years to form. Coal may take this long to form, but there is so much of it and costs very little to purchase, so it is one of the largest resources used in the world. There are 27 United States that still mine for coal to this day. The value of coal produced in the United States every year is estimated to be around $20 billion and
