"Only 43 percent of school districts in the United States test for lead in drinking water used by students in 2016 or 2017, according to a federal government report released Tuesday.
The report from the Government Accountability Office also found that of the 43 percent of school districts that test for lead in drinking water 37 percent found elevated levels above the level requiring action. The remaining 41 percent of districts said they did not test for lead and 16 percent of districts surveyed did not know if they tested for lead, according to the report.
No level of lead exposure is considered safe for children, according to the Centers for Disease Control. Lead can cause developmental delays, damage to the brain and nervous system, lower IQ, and hyperactivity."
