[2] The World Health Organization recommends limiting arsenic concentrations in water to 10 μg/L, although this is often an unattainable goal for ...
A dominant kind of metal toxicity is arsenic poisoning. This problem mainly arises from ground water that naturally contains high concentrations of arsenic.

The study, conducted in laboratory mice, suggests that people exposed to arsenic in their drinking water may be at increased risk for more serious illness or death from the virus. [149] Some Canadians are drinking water that contains inorganic arsenic. Private-dug–well waters are most at risk for containing inorganic arsenic.
Kids need water throughout the school day, whether they are in class or playing at recess. Making drinking water more accessible could improve their health, a new study found.
