A third of licensed daycares in Oregon failed to prove that their drinking water didn’t contain high levels of lead, The Oregonian/OregonLive found. Daycares in the state are required to test their water for the first time this year after reporting from the newsroom prompted a rule change. While child cares had until the end of September to submit their test results, data obtained by the Oregonian showed that five weeks after the deadline, the state still hadn’t received results from 1,280 daycares.

The state had results from 2,635 child cares, and 43 of those facilities — about 1.6 percent — discovered lead above state standards, records show. It was not immediately clear if children at each location consumed tainted water.
