Inconsistent Water Testing Exposes U.S. Schoolchildren to High Levels of Lead

By Sam NickersonMillions of children across the U.S. have been exposed to high concentrations of lead through their school drinking water due to inconsistent testing standards, a recent study found.Researchers at the Harvard T.H. Chan School of Public Health reviewed 25 state programs for testing for lead in schools' drinking water supply and found that there is no uniformity in states' approaches to develop initiatives to test for lead in school drinking water, action levels or maintaining water quality data — public schools in some states are not even required to perform testing on all drinking water taps.Moreover, the study revealed that 44 percent of nearly 11,000 schools had at least one sample test positive for lead levels at or above state action levels. The World Health Organization warns that "there is no known level of lead exposure that is considered safe" and research in the U.S. has linked even low levels of lead exposure with health and learning problems in children because of how it affects brain and nervous system development."Lead is a neurotoxin, it drops IQ scores, it's linked to aberrant behavior and violence," Howard Kessler, a retired doctor and part of Physicians for Social Responsibility, told The Guardian. "The concern is that while we are not taking much action, children are being damaged on a generational level. We are supposed to provide them with a safe environment, not poison them."High levels of lead have been found in school tap water since the toxic water crisis in Flint, Michigan became a national story in 2014, yet there is currently no federal requirement for schools to test water for lead, The Guardian reported, leaving the issue to the states.Of the 25 states in the Harvard report, researchers found that only 15 have laws or funding allocations for testing water in schools, while 10 have programs that are run through state environmental protection or health agencies. Few states provide funding for lead testing and remediation through school drinking water programs, the study found.
