  • 261 - Importance of Young Dissolved Organic Carbon to the Release of Arsenic in Aquifers -- Bostick
    Release Date: 09/07/2016

    Carbon from relatively new sources of organic material on the surface, or young carbon, can stimulate microbial communities deep in aquifers, leading to the release of arsenic into water, according to a recent field study by Columbia University Superfund Research Program (SRP) Center researchers. The researchers found that near-surface sources of organic carbon are central in microbial metabolism, even in aquifers that are far below and separated from the land where carbon is derived.

  • 208 - A Flurry of Arsenic Findings -- Ahsan, Jackson, Lu
    Release Date: 04/04/2012

    New evidence about arsenic abounds in SRP studies published recently. The studies reveal that food is an unexpected source of arsenic exposure, demonstrate adverse health effects are from low levels of exposure, show the mechanisms behind some of arsenic's health effects, and suggest a strategy for reducing exposure from well water.
