Slow arsenic poisoning of the contaminated groundwater users
This paper gives impact of Arsenic contaminated water on human health as well as overview of the extent and severity of groundwater arsenic contamination in Bangladesh. Scalp hair is the most important part of the human body to monitor the accumulation of this type of poison. Therefore, an experiment has been carried out by Neutron Activation Analysis (NAA) at Atomic Energy Research Establishment ...

Arsenic in private drinking water wells: an assessment of jurisdictional regulations and guidelines for risk remediation in North America
Arsenic is a known carcinogen found globally in groundwater supplies due to natural geological occurrence. Levels exceeding the internationally recognized safe drinking water standard of 10 μg/L have been found in private drinking water supplies in many parts of Canada and the United States. Emerging epidemiological evidence confirms groundwater arsenic to be a significant health ...

5 States with high levels of Arsenic in groundwater
Arsenic is a chemical element that enters the environment from mineral deposits, industrial activity, pesticides and the smelting of metals. In high levels, arsenic can cause toxicity, liver and kidney damage, and even cancer. In 2001, the U.S. Environmental Protection Agency (EPA) set a maximum contaminant level of 10 ppb for arsenic in all potable water. Since the standard went into effect ...

The effectiveness of arsenic remediation from groundwater in a private home
Abstract Private wells are the source of drinking water for approximately 15% of households in the United States, but these wells are not regulated or monitored by government agencies. The well waters can contain arsenic, a known carcinogen that occurs in groundwater throughout the nation at concentrations that can exceed the Maximum Contaminant Level defined by the U.S. Environmental Protection ...

Dynamic factor analysis for estimating ground water arsenic trends
Received for publication March 14, 2009. Drinking ground water containing high arsenic (As) concentrations has been associated with blackfoot disease and the occurrence of cancer along the southwestern coast of Taiwan. As a result, 28 ground water observation wells were installed to monitor the ground water quality in this area. Dynamic factor analysis (DFA) is used to identify common trends that ...

Project profile - quail ridge prescott, AZ arsenic treatment system
Background The Quail Ridge Community owns and operates the Quail Ridge Community water system located near Prescott, AZ. The water system is served by two wells that provide drinking water for the community’s residents at a maximum of 160 gallons per minute (gpm) with an approximate arsenic concentration of 13 parts per billion (ppb). After a successful pilot, the site was able to be ...

Solutions for removing arsenic from drinking water
Arsenic, a metalloid element, is found in many naturally occurring compounds. In its inorganic form, arsenic is toxic. Arsenic occurs naturally in some groundwater supplies worldwide, including in the drinking water supplies in parts of Taiwan, Japan, Bangladesh, and western South America. This is causing health problems, according to the American Cancer Society. Albuquerque, New Mexico, is the ...

3 Municipalities That Use AdEdge Solutions to Reduce Their Manganese - Case Study
Manganese is a naturally occurring mineral deposited from sediment and rocks. When present in high levels, manganese affects the taste of water and can cause staining on pipes and plumbing fixtures, as well as toxicity to plant life. To limit its effects, the U.S. Environmental Protection Agency’s (EPA’s) maximum contaminant level (MCL) for manganese is 0.05 mg/L. Here is how three ...
