这篇文章讨论了联邦上诉法院2月25日的一项裁决，该裁决支持美国环境保护局2000年12月修订的放射性核素规则，这几乎肯定会给威斯康星州沃克沙和其他数百个社区供水系统带来放射性核素问题，将镭和总α和β/光子发射器的浓度降至1976年首次设定的最大残留污染物水平（MCL），并达到30 ug/L的新铀标准。

This article discusses how a February 25th federal appeals court ruling upholding the US Environmental Protection Agency's revised radionuclides rule of December 2000 is all but sure to set Waukesha, Wisconsin, and several hundred other community water systems with radionuclides problems, on the compliance path to drop concentrations of radium and gross alpha and beta/photon emitters to the retained maximum contaminant levels (MCLS) first set in 1976 and to meet the new uranium standard of 30 ug/L.
