Arsenic is a naturally occurring metalloid present in groundwater in many countries. There are two forms of arsenic of which the inorganic form is highly toxic. You find this inorganic form of arsenic in groundwater. Arsenic in its inorganic form can contaminate water. In a laboratory study, iron oxide-coated sand showed promise as a medium for use in small systems or home-treatment units in developing areas of the world, for removing arsenic(III) and arsenic(V) from ground water. A low-cost, simple, home arsenic removal unit (material and fabrication cost: Rs. , cost of medium: Rs. 80, and regeneration. A recently published study by researchers at the University of Texas at Arlington found elevated levels of arsenic and other heavy metals in groundwater near natural gas fracking sites in Texas. Arsenic levels exceeding 10 μg/L are present in hundreds of private supply wells distributed over ten counties in eastern and southeastern Michigan. Most of these wells are completed in the Mississippian Marshall Sandstone, the principal bedrock aquifer in the region, or in Pleistocene glacial or Pennsylvanian bedrock aquifers. About 70% of ground water samples taken from Cited by:

Arsenic (As) is a metalloid element (atomic number 33) with one naturally occurring isotope of atomic m and four oxidation states (-3, 0, +3, and +5) (Smedley and Kinniburgh, ).In the aqueous environment, the +3 and +5 oxidation states are most prevalent, as the oxyanions Cited by: The goal of this book is to provide a description of the basic processes that affect arsenic occurrence and transport by providing sufficient background information on arsenic geochemistry and descriptions of hi- arsenic ground water, both affected and unaffected by human activity.
The most common source of arsenic contamination in ground water is the mobilization of naturally occurring arsenic on sediments. Given the right chemical conditions in the subsurface arsenic can dissolve into ground water used for drinking water.
Arsenic can have adverse health effects in people who drink water high in arsenic. ARSENIC IN GROUNDWATER. This pamphlet provides answers to questions about arsenic in drinking water.

Arsenic is an element (As) that occurs in the earth’s crust-rock, soil, all natural sources of exposure, or can be traced to deep water brines used to produce oil and natural gas. Previous Studies. In ground water, arsenic is commonly present in two oxidation states.
Arsenate (H n AsO 4 n-3) has an oxidation state of +5 and is the predominant form of arsenic in oxic te (H n AsO 3 n-3) has an oxidation state of +3 and is the predominant form in reducing the two forms, arsenite is the more toxic and the more mobile in solution.
Arsenic (As) causes health concerns due to its significant toxicity and worldwide presence in drinking water and groundwater. The major sources of As pollution may be natural process such as dissolution of As-containing minerals and anthropogenic activities such as percolation of water from mines, maximum contaminant level for total As in potable Cited by: Arsenic poisoning is a medical condition that occurs due to elevated levels of arsenic in the body.
If arsenic poisoning occurs over a brief period of time symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. Long-term exposure can result in thickening of the skin, darker skin, abdominal pain, diarrhea, heart disease, numbness, and Causes: Arsenic.
The release of arsenic from geothermal systems into surface and ground waters compromises the use of these waters as drinking water resources. In surface waters, As contamination can also adversely affect aquatic ecosystems, accumulating in sediments and plants.
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way down into 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.
Arsenic. Arsenic is a naturally occurring element found in soil and bedrock throughout Wisconsin. Under certain conditions, arsenic can be released into groundwater and enter water wells.
Long-term exposure to arsenic in drinking water is known to increase risks of skin, bladder, lung, liver, colon, and kidney cancer. The source of arsenic in water is often natural deposits in the ground that contaminate aquifers and wells. Contamination can also be caused by poor agricultural and industrial practices.
This element has a variety of industrial uses, and it's found in some paints and dyes, soaps, semiconductors, and in some metal alloys. Environmental occurrence.
Arsenic is the 20 th most common element in the earth’s crust, and is emitted to the environment as a result of volcanic activity and industrial activities.
Mining, smelting of non-ferrous metals and burning of fossil fuels are the major anthropogenic sources of arsenic contamination of air, water, and soil (primarily in the form of arsenic trioxide).

• This presentation covers strategies systems can use to lower the amount of arsenic in finished water. Arsenic in groundwater. Arsenic has become increasingly important in environmental geochemistry because of its significance to human health.
Long-term exposure to arsenic through drinking contamined water can result in a chronic arsenic poisoning. Known symptoms are: cancer of the skin, lungs, urinary blades, and kidney.
The source, transport and fate of arsenic in geothermal systems Jenny G. ~ebster' and D. Kirk ~ordstrom~ ' University qfAuckland, Auckland, New Zealand 2~~ Geological Survey, Boulder, CO, USA The release of arsenic from geothermal systems into surface and ground waters compromises the use of these waters as drinking water resources.
In surface. Abstract Arsenic concentrations in ground varies widely and regionally across the United States and exists as oxyanions having two oxidation states: As(+III) and As(+V). As(V) is effectively removed by most arsenic treatment processes whereas uncharged As(III) is poorly removed, thus, arsenic speciation is important in the selection and design of a treatment system.
As a natural part of the earth, Arsenic can be found all around us and it can be distributed throughout our environment through the air, land and water – including our drinking water. Inorganic arsenic can be naturally present in ground water in countries such as Argentina, China, Mexico and the United States of America.
