本研究项目的目的是确定含水层储存处理过的饮用水期间发生的水质变化。调查的重点是三卤甲烷（THM）和卤乙酸（HAAs），因为它们是饮用水氯化过程中产生的主要副产品，也是美国环境保护署（US Environmental Protection Agency）预计不久将对其进行监管的副产品；预计总THM和总HAA的最大污染物水平分别为80和60 ug/L。

The objective of this research project was to identify changes in water quality occurring during aquifer storage of treated drinking water. The focus of the investigation was on trihalomethanes (THMs) and haloacetic acids (HAAs), as these are the principal byproducts generated during the chlorination of drinking water and the ones expected to be regulated shortly by the US Environmental Protection Agency; maximum contaminant levels of 80 and 60 ug/L, respectively, are anticipated for total THMs and total HAAs.
