Abstract. Concentrations of naturally occurring arsenic in ground water vary regionally due to a combination of climate and geology. Although slightly less than half of 30,000 arsenic analyses of ground water in the United States were =< 1 µg/L, about 10% exceeded 10 µg/L.

Despite arsenic's reputation as a poison, it actually has fairly low toxicity in comparison with some other metals, although with chronic exposure there is some concern about arsenic's effect on chromosomes and its carcinogenicity.
