如果美国环境保护局（USEPA）6月3日的初步决定不监管第一污染物候选名单（CCL1）中的九种污染物中的任何一种，将不会为它们颁布新的饮用水标准，同时，将发布指导意见，以解决acan Thamoba造成的潜在眼部感染风险，并最终确定钠和硫酸盐的健康建议。

If the US Environmental Protection Agency's (USEPA's) preliminary decision of June 3 not to regulate any of nine contaminants on the first contaminant candidate list (CCL1) holds up, no new drinking water standards will be promulgated for them, while guidance will be issued to address potential eye-infection risks posed by acan-thamoeba and health advisories will be finalized for sodium and sulfate.
