Samples taken from water fixtures at three Portland Parks and Recreation facilities turned up elevated lead levels in 17 instances, the bureau revealed today, nearly a week after learning the results.

The Parks Bureau says five samples (out of 76) taken at the Portland Children's Museum exceeded 20 parts per billion for lead, the threshold beyond which the US Environmental Protection Agency recommends taking water fixtures in schools offline. The highest reading? A sink that turned up 115 ppb. Here's a rundown.

At Multnomah Arts Center, 11 out of 75 samples taken were above 20 ppb, the bureau says, with one sink turning up 447 ppb. The city says that sink is "located in a storage area, and has not been in use recently." Here are all the readings that caused concern at MAC:

A drinking fountain at the bureau's Mt. Tabor Annex, which hosts a preschool, also turned up lead above 20 ppb. "Preschool staff indicated that this fountain had not been used frequently at all," the bureau's release says.

Parks also took samples from water fountains and sinks at Fulton Community Center, and didn't find elevated levels in any of 12 tests. Sinks and fountains with high lead levels have been either shut off or marked with "do not drink" signs.

The findings come after the Parks bureau revealed June 5 that water testing at the Multnomah Arts Center had shown high lead levels in 2013, but that nothing was done to fix the situation until earlier this month. The bureau hasn't explained that lapse. Today's release says it's still looking into it.

“We have taken every step necessary to protect public health,” says Parks Commissioner Amanda Fritz says in the release. “We will continue to work to fix problems efficiently, and to provide information to our community as more details become available."

Parks Director Mike Abbaté plans to address the findings in a press conference this afternoon.
