  BIOGEOCHEMISTRY OF ARSENIC RELEASES TO GROUNDWATER, GLOBALLY AND IN NEW JERSEY
Julia Barringer
U.S. GEOLOGICAL SURVEY, TRENTON, NEW JERSEY

Arsenic at concentrations that exceed 50 micrograms per liter is found in groundwater on six continents. Unhealthful concentrations in groundwater have affected millions of people who rely on this source of drinking water.

Studies show that the redox environment and microbial activity are important factors in the release of arsenic from geologic materials to groundwater. Studies in New Jersey illustrate release mechanisms.
