据外媒报道，美国联邦环境保护局（简称环保局）的数据分析表明，大约350所学校和日托中心的供水系统于2012年到2015年期间未能通过铅测试。
研究人员称，这可能是非常非常大的问题，因为联邦政府只要求全国范围内大约10%的学校和一小部分日托中心进行铅测试，这意味着只有8225所运行自己的供水系统的学校与日托中心进行过铅测试。环保局估计，约9万所公立学校与50万儿童设备未能达到安全饮用水法的规定标准。因为他们依赖于市政公用设施提供水源，家长们期望市政供水系统会测试自己家的饮用水。

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.
