  • Treatment of perchlorate and other emerging contaminants in water and brines
    Patent number: 9067808
    Abstract: Cost-effective tailored earth materials and methods of making and using these tailored earth materials are disclosed. These tailored earth materials can be used to treat (filter) emergent contaminants, such as perchlorate, from water or brine. The sorbed contaminants on the spent tailored earth materials can be degraded after use by bioremediation.

  • Sulfur-based bulk reductants and methods of using same
    Patent number: 8722957
    Abstract: Provided herein are methods of treating a composition. In one embodiment, the method includes contacting a sulfur-based bulk reductant with a composition that includes soil and/or water and further includes one or more oxidized organic and/or inorganic compounds. In another embodiment, the method includes contacting a sulfur-based bulk reductant with a composition that includes soil and/or water and further includes one or more chlorinated organic compounds. In still another embodiment, the method includes contacting a sulfur-based bulk reductant with a composition that includes soil and/or water and further includes one or more chemical warfare agents. Also provided herein are sulfur-based bulk reductants for use in remediation of contaminated soil and/or water.
