Individual states can establish lower arsenic limits; New Jersey has done so, setting a maximum of 0.005 mg/L (5 ppb) for arsenic in drinking water. [30] A study of private water wells in the Appalachian mountains found that six percent of the wells had arsenic above the U.S. MCL of 0.010 mg/L. [31]
In the United States, she has tracked arsenic in groundwater in Maine [9] and considered how to best mitigate the risks associated with arsenic in drinking water. [10] Zheng has worked with others to develop a colorimetric assay to detect arsenic [11] [12] which facilitates testing for arsenic in groundwater. Based on her research, she ...
Arsenic poisoning is caused by incidental ingestion or inhalation of arsenic, typically from drinking contaminated well water, eating food cooked in contaminated water, or being exposed to arsenic-containing pesticides, folk medicines, or industrial chemicals. [8]
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.
A new study finds that honeybees forging across the U.S. ingest local pollutants, including arsenic and lead, which are detected in their honey. More than 260 samples were taken between 2020 and ...
In the U.S., the maximum level of inorganic arsenic that is allowed in drinking water is 10 parts per billion (ppb). In April, however, Consumer Reports noted that it had found levels of arsenic ...
The arsenic levels are up to 4730 μg/L in the groundwater, ~1000 μg/L in irrigation water, and up to 3947 μg/kg in food materials all of which all exceed the United Nations Food and Agricultural Organization's standard for irrigation water and the World Health Organization's standards for drinking water. As a result, individuals who are ...
The do-not-drink order went into effect Monday for about 9,000 Kennebec Water District customers in Waterville, Winslow, Benton, Fairfield and Vassalboro, and was lifted Tuesday afternoon ...
