Lead Testing - Water

HSD's Lead Testing Procedure - Drinking Water

Facilities built after 2000 and those that did not have elevated levels of lead during the testing in 2016 will be retested in ten years (2026). Other facilities will be tested every five years. The District will follow testing recommendations by the Oregon Department of Education, the Oregon Health Authority, and the EPA's 3Ts technical guidance on reducing lead in drinking water in schools.

2016 Testing for Lead in Drinking Water
In the early spring of 2016, Hillsboro School District began planning for comprehensive testing of all water sources in the district over the summer months. This testing was to include every possible source of drinking water in the district: every faucet, drinking fountain, and hose bib at every school and district facility. This included more than 5,700 samples.

The District's environmental safety contractor, PBS, conducted all of the sampling following the Oregon Health Authority's (OHA) guidance and the Environmental Protection Agency's (EPA) 3Ts technical guidance on reducing lead in drinking water in schools. The testing consisted of a first draw sample (water that has sat in the pipe between 8 and 18 hours) and a follow-up 30-second flush test. All samples collected were considered part of the test. If one sample showed lead content above the EPA's recommended action level of 20 parts per billion (ppb), the District immediately closed access to that fixture and tested the other sample to see if there was possibly a testing anomaly or if the water source was actually producing a high level of lead.

If the second sample showed a lead concentration below the EPA’s action level of 20 parts per billion (ppb), that water source was determined to be safe and was returned to service once the fixture was replaced.

If the second sample showed a lead concentration at or above 20 ppb, the fixture was capped pending the tracing of piping to determine the source of the lead, fixture replacement, and additional testing.
