The quality of drinking water in the United States has continued to improve over the past 40 years. The formation of the U.S. Environmental Protection Agency (USEPA) in 1971, the passage of the initial Safe Drinking Water Act (SDWA, PL 93-523) in 1974, and the passage of the 1996 SDWA Amendments (PL 104-208) represent significant progress in drinking water quality. While the widespread adoption of filtration and disinfection in the early 1900s virtually eliminated waterborne typhoid fever, some residual risks still remained 40 years ago. These national regulatory developments compelled USEPA and the drinking water community to address these remaining risks in drinking water and optimize risk reduction for the public.
美国的饮用水质量在过去 40 年中持续得到改善。1971 年成立的美国环境保护署（USEPA）、1974 年通过的首部《安全饮用水法》（SDWA，PL 93-523）以及 1996 年通过的《安全饮用水法修正案》（PL 104-208）都代表着饮用水质量方面的重大进展。尽管在 20 世纪初广泛采用过滤和消毒技术基本上消除了水传播的伤寒，但 40 年前仍存在一些残留风险。这些国家监管方面的发展促使 USEPA 和饮用水界解决饮用水中的这些剩余风险，并优化公众的风险降低措施。
