據(jù)外媒報道，美國聯(lián)邦環(huán)境保護局（簡稱環(huán)保局）的數(shù)據(jù)分析表明，大約350所學校和日托中心的供水系統(tǒng)于2012年到2015年期間未能通過鉛測試。

    研究人員稱，這可能是非常非常大的問題，因為聯(lián)邦政府只要求全國范圍內(nèi)大約10%的學校和一小部分日托中心進行鉛測試，這意味著只有8225所運行自己的供水系統(tǒng)的學校與日托中心進行過鉛測試。環(huán)保局估計，約9萬所公立學校與50萬兒童設備未能達到安全飲用水法的規(guī)定標準。因為他們依賴于市政公用設施提供水源，家長們期望市政供水系統(tǒng)會測試自己家的飲用水。

    An analysis of U.S. Environmental Protection Agency data showed about 350 schools and day-care centers failed lead tests a total of about 470 times from 2012 through 2015.

    But at this point it's impossible to know how big because the federal government requires only about 10% of the nation's schools and a tiny fraction of day cares — the 8,225 facilities that run their own water systems — to test for lead at all.

    The EPA estimates that about 90,000 public schools and half a million child-care facilities are not regulated under the Safe Drinking Water Act because they depend on water sources such as municipal utilities expected to test their own water. That means parents have no assurance lead isn't seeping into children's water from a school building's pipes, solder or fixtures.
