  • Importance of Young Dissolved Organic Carbon to the Release of Arsenic in Aquifers
    Research Brief - September 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.
