Despite increasing awareness of the issue of lead in drinking water, UC Nutrition Policy Institute and Harvard School of Public Health researchers found that many students in the U.S. attend public schools in states where not all taps are tested for lead, according to reports in various media outlets including The Guardian, NBC News and The Nation.
“All kids, no matter where they live, should have access to safe drinking water in school,” said Angie Cradock of Harvard's Prevention Research Center on Nutrition and Physical Activity, who led the study team. “Drinking water is important for helping kids grow up healthy, and water should be safe to drink.”
The researchers found that there is no uniformity in states' approaches to create and oversee programs to test for elevated lead in school drinking water. When collected, data are not regularly made available to guide action to reduce potential exposure to lead. About half of the country's students are at public schools in states that don't have programs or requirements to test drinking water in those schools.
Of the 24 states (plus Washington, D.C.) with a statewide program to test school drinking water for lead, only 12 states had data that could be analyzed by the research team. In these 12 states, 44 percent of all schools had at least one tap that tested higher than their state's threshold for action, and 12 percent of all samples had a lead concentration higher than the state's action level. The report also describes the features of statewide initiatives in operation between Jan. 1, 2016, and Feb. 28, 2018, in 24 states and the District of Columbia to conduct testing for lead in school drinking water.
