More Than 40 Percent of U.S. Schools Fail to Test for Lead in Drinking Water

California Requires Testing for Public Schools

WASHINGTON – Despite heightened concern in recent years about lead in drinking water, a troubling new report by the U.S. Government Accountability Office found that more than 40 percent of the nation’s schools failed to test for lead in 2016.

California is one of only eight states that requires public K-12 schools to test for lead, but the state law doesn’t apply to more than 10,000 privately operated child care centers. The legislature is now considering legislation that would require all licensed child care centers to test for lead in drinking water.

According to the GAO’s nationwide survey, roughly 43 percent of school districts, serving 35 million students, tested for lead in 2016. Of the districts that tested, 37 percent found lead at levels above the threshold the districts set for taking remedial action. All the districts that found elevated levels reported taking steps to lower lead, such as installing filters, replacing old water fountains, and providing students and employees with bottled water.  

The GAO said that 41 percent of schools, serving about 12 million students, did not test for lead in 2016. Sixteen percent of schools said they did not know if they had tested. No federal law requires lead testing in schools, and the GAO said only eight states require testing.

“This report should shock every member of Congress and jolt acting EPA Administrator Andrew Wheeler into action,” said Environmental Working Group President Ken Cook. “In the richest country on earth, none of our children should be attending schools where the drinking water is contaminated with a heavy metal that causes brain damage.”

“Our littlest children are highly susceptible to lead’s damaging effects and absorb as much as 50 percent of the lead they take in through drinking water,” said Susan Little, EWG’s senior advocate for California government affairs. “Testing of schools’ and child care centers’ drinking water is long overdue.”

The Environmental Protection Agency set its so-called action level of 15 parts per billion, or ppb, for lead in tap water from public water systems decades ago. It is not based on a safe exposure level for children, but was instead set to monitor a water system’s efforts to manage water corrosivity and minimize lead leaching from old pipes. Shockingly, for school water systems, the EPA’s action level for lead is 20 ppb, or one-third higher than the action level for public water systems.

In 2009, California set a public health goal for lead in drinking water at 0.2 ppb to protect against harms to the brains and nervous systems of children. This health guideline, which is not enforceable, was based on studies of children showing that an increase of one microgram of lead per deciliter of blood was correlated with a decrease of one IQ point.

EWG urges the federal government to set a protective legal limit for lead in drinking water, as it does for other water contaminants under the Safe Drinking Water Act. The EPA should require more aggressive action to monitor both schools and homes for lead contamination, and compel water companies to speed up their plans to replace water service lines. 

“Instead of working to deplete the EPA’s resources and authority to protect public health at the behest of polluters, President Trump and Acting Administrator Wheeler should demand that the agency gets whatever it needs from Congress to reduce the threat of lead in our drinking water,” said Cook.

Last year, EWG released a searchable national drinking water database that provides information about contamination in the tap water of virtually every American. The GAO’s report also provides guidance on what people can do to protect themselves and their families from the risks from lead in drinking water.
