美国环境保护局（USEPA）正在制定地下水饮用水系统消毒要求。地下水消毒规则监管工作组由美国环保局、各州、公用事业公司和其他利益相关方的代表组成，该工作组认识到，大多数使用真正地下水供应的饮用水系统与使用地表水的饮用水系统有很大不同。这些差异与系统的相对规模和经济环境以及当前的水源、类型和处理程度有关。 本文讨论了该规则的背景、问题、状态和方向。包括25个参考文献和表格。

The US Environmental Protection Agency (USEPA) is developing requirements for disinfection of groundwater-based drinking water systems. The Ground Water Disinfection Rule regulatory workgroup, made up of representatives from USEPA, states, utilities, and other interested parties, recognizes that most drinking water systems using true groundwater supplies are substantially different from those using surface water. These differences have as much to do with the systems' relative sizes and economic circumstances as with the source water and types and degree of treatment currently in place. This article discusses the context, issues, status, and directions of this rule. Includes 25 references, tables.
