Alkyl halides are the most prevalent groundwater contaminants in the United States and are significant components of hazardous wastes. The potential for biological transformation of these compounds has been found only recently. In-situ biotransformation appears an excellent possibility for cleansing groundwaters of these contaminants, but a better understanding of the microorganisms and environmental factors is clearly needed. Good potential also exists for use of biological processes for treatment of hazardous wastes. Studies will be conducted on environmental factors affecting rates of biotransformation of alkyl halides and intermediates formed using pure cultures of microorganisms observed to bring about the transformations. Environmental factors of interest are redox environment, temperature, electron donors and acceptors, and microbial species.

烷基卤化物是美国最普遍的地下水污染物，也是危险废物的重要组成部分。 最近才发现这些化合物的生物转化潜力。 原位生物转化似乎是净化地下水中这些污染物的绝佳可能性，但显然需要更好地了解微生物和环境因素。 使用生物工艺处理危险废物也存在良好的潜力。 将研究影响卤代烷生物转化率的环境因素以及使用观察到的微生物纯培养物形成的中间体带来的转化。 感兴趣的环境因素是氧化还原环境、温度、电子供体和受体以及微生物种类。
