For example, median levels in Nevada were about 8 μg/L [15] but levels of naturally occurring arsenic as high as 1000 μg/L have been measured in the United States in drinking water. [16] Groundwater associated with volcanics in California contain As at concentrations ranging up to 48,000 μg/L, with As-bearing sulfide minerals as the main ...
Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deep tube wells for water supply in the Ganges Delta , causing serious arsenic poisoning to large numbers of people.
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 ...
State reveals that beach debris in Keyport has high levels of arsenic. Gannett. Amanda Oglesby, Asbury Park Press. August 5, 2024 at 12:48 PM.
Increased levels of skin cancer have been associated with arsenic exposure in Wisconsin, even at levels below the 10 ppb drinking water standard. [147] According to a recent film funded by the US Superfund , millions of private wells have unknown arsenic levels, and in some areas of the US, more than 20% of the wells may contain levels that ...
The massive 20-year cleanup of a toxic legacy in south Minneapolis has now eliminated arsenic contamination for all but one residential yard, the Environmental Protection Agency announced Friday.
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 ]
The product was found to contain 13.2 parts per billion (ppb) of arsenic, which is above the action level of 10 ppb. The product was available at Walmart stores in 25 states including Puerto Rico ...
