Arsenic in drinking water

Chemical Contaminant Rules

One solution is "By using surface water and instituting effective withdrawal regulation. Technologies for arsenic removal include oxidation, coagulation-precipitation, absorption, ion exchange, and membrane techniques. The organs of the body that are usually affected by arsenic poisoning are the lungs, skin, kidneys, and liver.

In this case, the arsenic is exchanged for chloride. Groundwater comes from deep tubewells, which are few in number. Current consensus on the mode of carcinogenesis is that it acts primarily as a tumor promoter. Seven of the twenty districts of West Bengal have been reported to have ground water arsenic concentrations above 0.

What to do if your drinking water contains arsenic

No chemicals are used and almost no sludge is produced during operational stage since iron and arsenic compounds are rendered inactive in the aquifer itself.

The higher the level and length of exposure, the greater the risk. Do I have arsenic in my water? What types of treatment solutions are available to private well owners? Other adverse health effects that may be associated with long-term ingestion of inorganic arsenic include developmental effects, diabetes, pulmonary disease, and cardiovascular disease.

According to a British Geological Survey study in on shallow tube-wells in 61 of the 64 districts in Bangladesh, 46 percent of the samples were above 0. Iron removal processes can be used to promote arsenic removal from drinking water via adsorption and co-precipitation. As a result, there is no reliable estimate of the magnitude of the problem worldwide.

No chemicals are used and almost no sludge is produced during operational stage since iron and arsenic compounds are rendered inactive in the aquifer itself.

Drinking Water Contaminants – Standards and Regulations

In fact, using iron electrocoagulation to remove arsenic in water proved to be the most effective treatment option. Consequently, if the arsenic in the source water is predominately As IIIthen oxidizing As III to As V with a chemical oxidant such as chlorine will result in a higher arsenic removal efficiency.

Arsenic is odorless and tasteless. Groundwater comes from deep tubewells, which are few in number. Who can I contact for more information or questions?

Arsenic contamination of groundwater

Arsenic in Bangladesh has attracted much attention since recognition in the s of its wide occurrence in well-water in that country.Low-arsenic water can be used for drinking, cooking and irrigation purposes, whereas high-arsenic water can be used for other purposes such as bathing and washing clothes.

Discriminate between high-arsenic and low-arsenic sources. Arsenic levels tend to be higher in drinking water that comes from ground sources, such as wells, as opposed to water from surface sources, such as lakes or reservoirs. Arsenic levels in public drinking water are regulated in the United States by the Environmental Protection Agency (EPA).

Arsenic: The EPA estimated in that nearly 36 million Americans drank water containing arsenic at or above 3 parts per billion—the level NRDC had urged be established as a drinking water.

Sep 20,  · Long famed for its homicidal toxicity at high doses, a number of studies suggest that arsenic is an astonishingly versatile. The Drinking Water Standard for Arsenic Fact Sheet provides information on the potential health effects from exposure to arsenic, an overview of the Final Rule, and background information on the natural occurrence of arsenic.

Arsenic, a naturally occurring element, is one of the many drinking water contaminants actively monitored by drinking water systems because it can result in adverse health conditions, including an increased risk for a range of cancers.
