Arsenic is a common natural contaminant of well water and is highly carcinogenic. Iron oxide adsorption treatment for arsenic in groundwater is a commonly practiced removal process which involves the chemical treatment of arsenic species such that they adsorb onto iron oxides and create larger particles that may be filtered out of the water stream.
Arsenic contamination of ground water is found in many countries throughout the world, including the US. [2] The World Health Organization recommends limiting arsenic concentrations in water to 10 μg/L, although this is often an unattainable goal for many problem areas due to the difficult nature of removing arsenic from water sources.

Arsenic poisoning (or arsenicosis) is a medical condition that occurs due to elevated levels of arsenic in the body. [4] If arsenic poisoning occurs over a brief period of time, symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. [1]
The DNR had agreed to the use of Well 9 if the city would add ferric chloride to the water to reduce arsenic levels. ... misleading to say the Well 9 system was intermittent when meter data showed ...
Arsenic exposure can lead to skin lesions, a variety of cancers, gastrointestinal bleeding, liver damage, kidney failure, gangrene, cardiovascular disease and other health affects, according to ...
In fact, when ingested, arsenic — a natural element found in the earth's crust — can affect several organs and systems, including the nervous, respiratory, cardiovascular, immune and endocrine ...
Arsenic poisoning is a global problem arising from naturally occurring arsenic in ground water. The evidence that arsenic may be a beneficial nutrient at trace levels below the background to which living organisms are normally exposed has been reviewed. [ 3 ]
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
