LOSD releases more lead-testing results
The Lake Oswego School District posted results Monday for lead testing in water fixtures at Lakeridge High, Lake Oswego High, Oak Creek, Hallinan and the former Uplands Elementary building.
Only Hallinan had a fixture with lead levels above what's recommended, the district said, and that fixture was shut off.
LOSD staff drew water samples for initial testing in June 2016. The district performed follow-up testing at schools in November 2016, checking any fixture that "could be used to fill a water bottle, drinking fountains, hand-washing stations and sinks." Since then, the district has been releasing results as they become available.
The Environmental Protection Agency recommends schools take fixtures out of service if they're used for drinking water and lead levels exceed 20 parts per billion. In the results announced this week, just one fixture tested above 20 ppb. It was at Hallinan (built in 1980), which had 29 fixtures tested.
In Room 16, a stainless steel sink with a faucet and drink-
ing fountain that could be used for drinking tested at 28.4 ppb.
"Students more frequently use a hallway water fountain with colder water," the district's website says. Nevertheless, the fixture was shut off and will remain out of service until a reverse-osmosis filter is installed and a water sample is retested.
Water samples were drawn from 30 fixtures at Lakeridge High (built in 1970) and none tested higher than 20 ppb, the district said. At LOHS (built in 2005), 58 fixtures were tested and also had no lead levels higher than 20 ppb.
Oak Creek Elementary (built in 1991) had 30 fixtures tested, and Uplands (built in 1961) had 31. No readings higher than 20 ppb were recorded at either school, according to the district.
The results for several other schools already have been released and are available online at www.tinyurl.com/LOSDHealthyandSafe.
