Currently, there is no uniformity in states’ approaches to create and oversee programs to test for elevated lead in school drinking water. Many students in the U.S. attend public schools in states where not all taps are tested for lead. In states where water was testing and data were publicly available, nearly half of the schools identified one or more water source with elevated levels of lead. The brief, State Policies on Testing Drinking Water for Lead in U.S. Schools, is based on a study from researchers at the Harvard T. H. Chan School of Public Health and the University of California Nutrition Policy Institute.
