1986年《安全饮用水法》修正案将影响美国各地的供水设施。作者描述了这些影响，并提出了在新法律全面实施后，为满足新法律的要求可以采取的准备措施。自来水公司必须处理新的污染物标准，包括安装新的处理技术，以满足这些新标准。井口保护计划以及地下水和地表水供应所需的消毒将改变许多系统目前的运行方式。对消毒副产品进行更严格的监管，再加上足以应对病毒和贾第虫的消毒，将产生深远的影响，这将导致水处理中潜在冲突目标的微妙平衡。 包括7个参考文献、表格、图表。

Water utilities throughout the United States will be affected by the 1986 amendments to the Safe Drinking Water Act. The authors describe these effects along with suggesting preparations that can be undertaken to meet the requirements of the new law when it is fully implemented. Water utilities must deal with new contaminant standards, including installation of new treatment technologies that may be needed to meet these new standards. Wellhead protection programs and required disinfection of groundwater and surface water supplies will change the way in which many systems now operate. The far-reaching effects of more stringent regulation of the by-products of disinfection, coupled with disinfection adequate to contend with viruses and Giardia, will cause an exquisite balancing of potentially conflicting goals in water treatment.
