Arsenic poisoning, or arsenicosis, happens when a person takes in dangerous levels of arsenic. Arsenic is a natural semimetallic chemical that is found all over the world in groundwater.
Of the 1,928 wells sampled for arsenic between September 2002 and March 2003, 72 wells (%) exceeded the federal drinking water standard of 10 ppb with the highest level reported at 216 ppb (data on levels above 5 ppb, the NJ arsenic MCL, have not been publicly reported).

Arsenic levels in groundwater across the By Jared Bennett and Chris ZubakSkees. June 28, 2014. Arsenic makes up part of the Earth’s crust and is commonly found in groundwater.
Metals such as arsenic, cadmium, lead and mercury are natural occurring chemical compounds. They can be present at various levels in the environment, soil, water and atmosphere.
ARSENIC IN WELL WATER . Guidance . Introduction The Michigan Department of Environmental Quality (DEQ) recommends that homeowners have their well water tested for arsenic. Arsenic is a chemical element that naturally occurs in the earth’s mineral deposits and dissolves in groundwater. Michigan has naturally higher arsenic levels in groundwater.
Drinking Water Wells in Oregon . Introduction . Arsenic is a naturally occurring element found in soils and groundwater. Arsenic concentrations vary in accordance with geographic location. When arsenic levels are found to be too high at a specific location, it may be necessary to treat drinking water to remove it. Arsenic usually exists in two ...
Arsenic in your water? Economists study perceptions of risks from drinking water high in arsenic. Story by Kathy Wythe. In several "hot spots" across the United States people may be drinking water with high levels of naturally occurring arsenic without understanding the associated risks, according to …
Jul 01, 2014· Arsenic levels tend to be higher in drinking water that comes from ground sources, such as wells, than from water from surface sources, such as lakes or reservoirs. For additional details on arsenic and water, including testing, level, measurement, and removal information, please see the NIEHS Fact Sheet on Arsenic (676KB).
Sep 20, 2013· Arsenic also interferes with the normal function of immune cells. It damages lung cells and causes inflammation of cells in the heart. Researchers first became aware of these problems in socalled hot spot countries like Bangladesh, where arsenic levels in water can top 1 part per million.
Remember to regularly test your water as it can change over me. High levels of arsenic can cause skin rashes, stomach issues, or cancer. Infants and young children are especially sensi tove arsenic as high levels can increase the risk of lung cancer and may aﬀect learning. If your arsenic level is:
Removing arsenic from drinking water Do not boil the water! Boiling contaminated water does not remove arsenic and can increase arsenic levels. For public drinking water system operators: Arsenic can be reduced or removed entirely from drinking water, but treatment processes require careful maintenance and monitoring.
Drinking Water Arsenic Rule History On January 22, 2001, EPA adopted a new standard for arsenic in drinking water of mg/l or 10 parts per billion (ppb), replacing the old standard of 50 ppb. Water systems had to meet the new standard by January 23, 2006.
Arsenic in Drinking Water: MCL Status. Public health concerns about arsenic in drinking water related to its potential to cause adverse health effects are addressed through the adoption of state and federal drinking water standards, also called maximum contaminant level (MCLs)
Here's how to test and treat your drinking water well for arsenic ... Federal standards allow public drinking water supplies to have arsenic levels of up to 10 parts per billion (ppb), but these standards do not apply to private well owners (that's left up to the well owner to determine).
Once released, arsenic remains in the environment for a long time. Arsenic is removed from the air by rain, snow, and gradual settling. Once on the ground or in surface water, arsenic can slowly enter ground water. High arsenic levels in private wells may come from certain arsenic containing fertilizers used in the past or industrial waste.
Arsenic in Drinkingwater Background document for development of WHO Guidelines for Drinkingwater Quality. ... Water The level of arsenic in natural waters, including open ocean seawater, generally ranges between 1 and 2 µg/l (Hindmarsh McCurdy, 1986; USNRC, 1999).
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. Longterm exposure to arsenic in drinking water is known to increase risks of skin, bladder, lung, liver, colon, and kidney cancer.
Exposure to arsenic in drinking water has been identified as a health concern in regions of the United States where bedrock contains unusually high levels of arsenic, such as areas of New Hampshire, Maine, Michigan, and regions in the Southwest and the Rockies.
What are EPA's drinking water regulations for arsenic? In 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine the level of contaminants in drinking water at which no adverse health effects are likely to occur.
A. There is a standard level for permissible air levels of arsenic in the workplace. B. There is a standard level for allowable arsenic in drinking water. C. There is a standard level for allowable arsenic in ambient air in the environment. D. There are permissible levels of organic arsenic set for foodstuffs by the FDA. Answer:
In water, levels of arsenic are lowest in seawater, higher in rivers and lakes and highest in water from underground areas containing volcanic rock or arsenicrich mineral deposits. The background levels of arsenic in soil and sediment increase if there are natural and/or manmade sources of arsenic contamination present.
An understanding of the status and trends of arsenic concentrations in ground water can: (1) assist water managers and users in overcoming adverse health effects through avoidance or treatment; (2) provide a basis for evaluating the costs of adopting a particular value for a drinkingwater standard (or MCL Maximum Contaminant Level); and (3 ...
