  • Nitrous Oxide Halts Breakdown of Chlorinated Compounds
    Research Brief - April 2019
    A new Superfund Research Program (SRP) study showed that nitrous oxide (N2O), a groundwater contaminant commonly generated from agricultural runoff, inhibits bacterial degradation of certain chlorinated contaminants, including tetrachloroethene (PCE). The study may explain why bioremediation, or the use of bacteria to break down compounds, can stall at some hazardous waste sites.
