Lead Testing of School Drinking Water

The federal Government Accountability Office. surveyed school districts across the country on testing for lead in drinking water in 2017. Based on our nationally generalizable survey, we estimate that:

• 41% of districts, serving 12 million students, had not tested for lead in the 12 months before completing our survey.
  43% of districts, serving 35 million students, tested for lead. Of those, 37% found elevated levels and reduced or eliminated exposure.
  16% did not know if they had tested.

At least 8 states require schools to test for lead, and many others assist with voluntary testing.
