Lead in Drinking Water for Health Care Providers; Information about Water Lead Levels and School Test Results

October 29, 2018
As part of a voluntary water testing program, school officials recently detected elevated lead levels (>15 parts per billion (ppb)) in some drinking water samples at Fairmont Junior High. As Boise School District continues to test other schools, there may be additional public announcements about elevated water lead levels in fountains or faucets. Parents may have questions about the risk to their children’s health, or about the need for blood lead testing. As CDC case studies have demonstrated, exposure to a water source with elevated lead levels does not necessitate blood lead testing (CDC, 2004; 2010; 2012; 2016). Lead levels in Boise’s drinking water are not elevated so lead is typically from the fixture or plumbing components. Full HAN Message

Zika Virus Testing Update for Health Care Providers

Idaho Bureau of Laboratories (IBL) provides testing for emerging diseases when diagnostic testing is limited or nonexistent in the commercial sector. Zika virus testing was a recent example of this.
