This SBIR project proposes to develop a system for detoxifying contaminated groundwater using in-situ anaerobic bioremediation. The focus of the project will be the ability of multi-functional nano-powders to produce groundwater that supports effective in-situ anaerobic bioremediation. This improved method would use organic bio-amendments applied with anaerobic microbes to contaminated groundwater.The broader/commercial impacts of the proposed project will be to treat contaminated groundwater in a more cost-effective manner. Halogenated hydrocarbons, perchlorate, and other toxic substances contaminate groundwater and threaten public water supplies. The slow natural attenuation of TCE and other toxic chemicals makes effective in-situ treatment that much more important. In-situ methods, where the contaminants are consumed underground, is lower cost than pump and treat options and is a more complete remediation solution.

该SBIR项目建议开发一个系统，利用原位厌氧生物修复技术对受污染的地下水进行解毒。 该项目的重点将是多功能纳米粉末产生地下水的能力，支持有效的原位厌氧生物修复。 这项改良的方法会使用有机生物改良剂，加上厌氧微生物，以处理受污染的地下水。拟议项目的更广泛/商业影响，是以更具成本效益的方式处理受污染的地下水。 卤代烃、高氯酸盐和其他有毒物质污染地下水，威胁公共供水。三氯乙烯和其他有毒化学品的缓慢自然衰减使得有效的原位处理变得更加重要。 污染物在地下消耗的原位方法比泵送和处理方法成本更低，是一种更全面的补救解决方案。
