美国环境保护局正在评估几种饮用水消毒剂及其副产品的性能和潜在健康风险。为了为该评估提供现场数据，并更彻底地了解消毒和消毒副产品控制之间的相互作用，以及所选方向的优缺点，在两家饮用水公用事业公司进行了研究。本文将讨论这些研究的一些结果，其中包括在路易斯安那州杰斐逊教区和长凳的中试工厂评估- 印第安纳州埃文斯维尔的规模评估。路易斯安那州对氯、氯胺、二氧化氯和臭氧进行了研究；本研究的主要目的是评估消毒剂的微生物有效性、卤化副产品的控制以及与使用这些消毒剂相关的潜在健康影响。在印第安纳州的研究中，二氧化氯与氯进行了比较。

The U.S. Environmental Protection Agency is in the process of assessing the performance and potential health risks of several drinking water disinfectants and their by-products. To provide field data for this assessment and to more thoroughly understand the interactions of disinfection and disinfection by-product control regarding the advantages and disadvantages of a selected direction, studies were done at two drinking water utilities. This paper will discuss some of the results from these studies which consisted of a pilot plant evaluation at Jefferson Parish, Louisiana and bench-scale evaluations at Evansville, Indiana. Chlorine, chloramine, chlorine dioxide, and ozone were studied in Louisiana; the major objectives of this study were to evaluate the microbiological effectiveness of the disinfectants, the control of halogenated byproducts, and potential health effects associated with the use of these disinfectants. Chlorine dioxide was compared to chlorine in the Indiana study.
