All of Lake Oswego School District's water test results are now in, and the results indicate that nine fixtures at local schools had elevated lead levels, four of them at Lakeridge Junior High School.
The Environmental Protection Agency recommends that any fixture with levels above 20 parts per billion of lead should be shut off, and the district says it did so.
LOSD staff drew water samples for initial testing in June 2016. The district performed follow-up testing at some schools in November 2016, checking any fixture that "could be used to fill a water bottle, drinking fountains, hand washing stations, and sinks. "The district has been releasing the results since then, according to the district website.
Here is an overview of the lead results at any fixture that tested above recommended levels, according to the LOSD website:
Hallinan, Room 16: A classroom sink with faucet and drinking fountain that can be used for consumption tested at 28.4 ppb;
Lake Grove, Room 14B: A sink/fountain in the Learning Center with "infrequent use" tested at 55.4 ppb;
Lake Grove, Room 17: A sink/fountain in one of the Access rooms used for small group instruction with "infrequent use" tested at 25.5 ppb;
Westridge, Room 23: A sink in computer lab that was "not accessed by students" tested at 23.3 ppb;
LOJ in the boys' locker room: A drinking fountain tested at 29.3 ppb;
LJHS in Room 24: A classroom sink in a math classroom with "very limited use" tested at 25.2 ppb;
LJHS in the kitchen: A hand-washing sink "not used for direct food prep" tested at 54.8 ppb;
LJHS in the kitchen: A hand-washing sink "not used for direct food prep" tested at 20.6 ppb; and
LJHS in Room 25: A classroom sink in a science classroom "used for cleaning experimental glassware" tested at 19.4 ppb.
"All other fixtures at all schools that could reasonably be used for water consumption or food preparation had either no detectable levels of lead or were below the EPA action level," the district announc-
ed in its newsletter, The Current.
To determine what future action should be taken, the LOSD has contacted the Lead Program at the Multnomah County Health Department and the City of Lake Oswego Water Treatment Plant. The results for all district schools are available online at http://tinyurl.com/LOSDHealthyandSafe.
