Arsenic Awareness Community Outreach in Bangladesh

Field Studies at Superfund Site in New Jersey

The Columbia Superfund Research Program investigates the health effects, geochemistry, and remediation of Arsenic (As) and Manganese (Mn), with a particular focus on groundwater.

The contamination of groundwater and soils with As and Mn is associated with major public health, remedial, and environmental policy problems both in the U.S. and abroad. Our interdisciplinary teams of bio-medical and geoscience researchers and students work with government scientists to better understand underlying exposure routes, pathophysiological mechanisms, and population dynamics that contribute to the risks from As and Mn and to translate new findings into effective policies that reduce environmental exposures and improve human health.
