The Effects Of Arsenic On Drinking Water Essay

Under the Safe Drinking Water Act, the U.S. Environmental Protection Agency (EPA) is required to establish the concentrations of contaminants that are permitted in public drinking-water systems. A public water system is defined by EPA as a “system for the provision to the public of water for human consumption through pipes or other constructed conveyances, if such system has at least fifteen service connections or regularly serves at least twenty-five individuals” (63 Fed. Reg. 41940 [1998]). Section 1412 of the act, as amended in 1986, requires EPA to publish maximum-contaminant-level goals (MCLGs) and promulgate national primary drinking-water regulations (maximum contaminant levels [MCLs]) for contaminants in drinking water that might cause

Due to its physical characteristics (no odor, no color, and no flavor), arsenic exposure is often unnoticed, especially when ingested through drinking water. Therefore, the key to prevention of Dermatofibroma is understand the risk factors whether environment such as chronic arsenic exposure due to the ingestion of naturally-contaminated water, groundwater contamination due to leaching of arsenic from rocks and soil frequently results in concentrations above 50 mcg/L, which are associated with carcinogenesis in humans. Occupational exposure via inhalation of arsenic-containing vapors occurs during smelting, mining, refining, electroplating, and manufacturing of decorative-glass, pesticides, gallium arsenide computer microchips, and pressure-treated wood. Documented regions with natural groundwater arsenic contamination include Millard County, Utah; Lane County, Oregon; Lassen County, California; Fallon, Nevada; Fairbanks, Alaska; and New Hampshire, also persons living in the southwestern United States are at higher risk for being exposed to elevated levels of arsenic in drinking water.

There currently is no concrete clinical-pathological evidence

There are three main mechanisms by which the chemical composition of groundwater, which is our natural source of drinking water, may be changed: by natural processes, by man's waste-disposal practices such as those for sanitary wastes, liquid industrial wastes, solid wastes, and radioactive wastes, and by spills, leaks, and agricultural activities and other sources unrelated to disposal. The degree of risk posed by contaminants varies according to many factors. These include the volume and toxicity of the contaminant, its concentration in the aquifer, its persistence in the environment, and the degree of human and environmental exposure to the contaminant. In addition, the number of persons affected, or likely to be affected, over time and the percentage of available groundwater both locally and regionally should be taken into consideration. If the contaminants in the groundwater exceed the standards set for drinking water by the federal government, for example, then the water is hazardous for the use for which it was designated under the standards. These standards include, however, only a limited number of chemicals, and thus they do not necessarily protect humans or the environment against either the short-term or the long-term effects of every contaminant that might be found in

The impending crisis in India would be a good opportunity to study the effects of the poison and perhaps show the rest of the world the importance of awareness and spark them into action. Arsenic is a destructive element that must be contained and controlled. Up until now, few individuals know much about the impacts of arsenic. This is shocking since it is a element that will undoubtedly influence the lives of many individuals on this planet in the following couple of

Imagine you're drinking a cup of water and every single drop is poison. This could be happening to you. 50% of the United States have lead in their drinking water. This is because of lead based pipes. Lead based pipes have been leaching lead into water which connects to drinking water. It can also be because of the state's water utilities that might have lead in their water. ( EPA's safe drinking water information system database reports, three, 2016 by Isabella DC, USA Today) says Lead can cause brain damage, cancer, seizures, hearing loss, learning disabilities, and more!

While nitrates are one of the major contaminants in the area, San Joaquin Valley residents face drinking water pollution from many other sources including arsenic, coliform bacteria, and pesticides. Arsenic is a naturally occurring semi-metal element that is found in different types of rocks. While arsenic primarily occurs naturally, human activities impact the amount of arsenic in groundwater. Arsenic is not only toxic at high concentrations, but also harmful after prolonged exposure at moderately elevated levels. California recognizes arsenic as a human carcinogen and believes prolonged exposure to the element to be associated with various cancers, including skin, bladder, kidney, lung, and liver cancers. A study in Maine found a connection between water contaminated

There is a higher likelihood of being exposed to arsenic via food ingestion compared to inhaling arsenic-contaminated air or drinking arsenic-contaminated water. Once the arsenic has been absorbed through the lungs or gastrointestinal tract, the arsenic is distributed through the body via the bloodstream. For metabolism, in the blood stream, the arsenic becomes attached to the red cells, white cells, and cells that can convert arsenate to arsenite. Some of those arsenites are taken to the liver, where they are methylated by the enzymatic transfer of the methyl group from S-adenosylmethionine (SAM) and the arsenite are converted into methyl arsonate (MMA V) and dimethyl arsenate (DMA V). Those metabolites, methyl arsonate and dimethyl arsenate, are then ready to be excreted. If the liver is at its limit of methylation, excess arsenites are stored in the body’s soft tissues. Arsenic and its many variations (ie. MMA V, DMA V, arsenate, and arsenite) are excreted through the kidneys. There is a possibility that two to four weeks after being exposed to arsenic, some of the arsenic can still be found in the human’s hair, nails, skin, and bones and teeth (ATSDR,

illegal level of bacterial growth. This study also found high levels as high as 13 parts per billion of arsenic tap water is only allowed to have 5 parts per billion.

You may well know that aluminium, along with a number of other contaminants, can be found in your drinking water but did you know why it’s in your drinking water? More importantly, do you know if it’s even safe? Aluminium is already present in our soil and as a result will be found in untreated sources of drinking water such as wells. On top of this, aluminium compounds are also used to help remove any impurities at water treatment works. Aluminium happens to be very useful in the battle against cloudiness and bacterial content before the water enters the final stages of disinfection and treatment however, as a result of its use a residual amount remains in the water supply. The legal standard for

Toxic chemicals such as lead and mercury in our environment have links to the causes of cancer, birth defects and mental illness. How can Americans be certain that the water in their household is safe to drink and toxic free? For the people in Flint, Michigan, it is too late for many have been already affected by such toxicity in their water supply. Toxic chemicals in our environment must be better controlled and America’s infrastructure must be properly repaired. This is an urgent need and the elected leaders must be held accountable for any neglect of this most important issue.

This chemical tends to occur naturally in soil, so sometimes it can make its way into your well. If you drink too much water contaminated with arsenic, you will be susceptible to an array of harsh side effects such as vomiting and a burning feeling. If your water supply is never checked and you drink arsenic-laced water regularly over time, your risk factor for developing several kinds of cancer will increase substantially.

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

According to the Associated Press, the FDA stated that chicken sold on the markets across USA are fed with inorganic arsenic, a detrimental chemical for human health. It’s given to chicken because it causes quicker weight gain and less feeding. It’s also given to turkeys, hogs, and chickens for enhanced color.

The purpose of this report is to propose a solution to the problem of reduced drinking water quality due to chemical pollution. Some bodies of water in the United States are becoming polluted from chemicals and restrictions are needed to protect drinking water quality.
