&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Arsenic is a widespread element traced in groundwater in varying concentrations in the United States (Welch 589). As a result, drinking water in the region contains a substantial concentration of this element, which has raised serious health concerns. This has called for the regulation of drinking water by the Federal and State standards that control public water systems (U.S. Environmental Protection Agency 1). The U.S. Environmental Protection Agency (USEPA) has ruled that the measure of arsenic concentration should be between 50 and 10 micrograms per liter. However, moderate to high (10-50 micrograms) arsenic concentrations have been present in groundwater in eastern New England. Moreover, a significant number of wells are above-average concentrations in New England (Loiselle 5).
