Lake Oswego calls lead test results 'encouraging'
Eighteen of 20 taps in City-owned buildings show no detectable lead; two faucets are being replaced
Eighteen of 20 samples taken over the summer from taps in City-owned buildings in Lake Oswego showed no detectable lead in the water, officials said Tuesday, and a 19th sample was below the level at which further testing is required.
The one sample that exceeded the Environmental Protection Agencys action level of 15 parts per billion came from the laundry room faucet at the Main Fire Station on B Avenue; it measured 41.1 ppb. An investigation regarding the source of the lead is underway, City officials said, and the faucet has been replaced.
The other sample with a trace of detectable lead was the Adult Community Center drinking fountain, at 5.1 ppb. Although the result is well below the action level of 15 ppb, City officials said that fountain will also be replaced.
"While there is no requirement to test for the presence of lead in the water in City-owned buildings, we wanted to be proactive, to reduce any potential exposure," said Kari Duncan, the Citys water treatment plant manager. "These are pleasing results that indicate the treatment process and corrosion control system is working effectively and the plumbing in the City's buildings contains no or little lead."
Samples were collected at the Main Fire Station, South Shore Fire Station, Westlake Fire Station, Jean Road Fire Station, Palisades School, Adult Community Center, City Hall, Golf Course, Tennis Center and the Library. The results of City facility lead testing can be found at www.lakeoswego.city/city-building-lead-results.
Water Treatment Plant staff have also responded to water customer requests for lead samples this year. Of the 25 homes, churches and day care facilities tested in Lake Oswego in 2016 at the owners request, all samples have been below the action level of 15 ppb and the majority have had no detectable lead in the water, officials said.
The main source of lead in drinking water is typically from household plumbing or components associated with service lines.
