How does lead get into drinking water?
Lead can enter drinking water when service pipes that contain lead corrode, especially where the water has high acidity or low mineral content that corrodes pipes and fixtures. The most common problem is with brass or chrome-plated brass faucets and fixtures with lead solder, from which significant amounts of lead can enter into the water, especially hot water.
When does the Medford School District test for lead?
The Medford School District has been testing for lead in the drinking water for more than a decade. As a part of the bond work, the MSD took the opportunity to test and upgrade vast amounts of plumbing. Since the bond, all schools have been spot checked on an annual basis. During the summer of 2016 all fixtures used for drinking water and food preparation were tested. Going forward, we will continue to spot check all schools annually (Elementary’ s – four tests and Middle/High Schools eight tests) and test all fixtures at a site every six years.Helpful Links:
