Several decades ago the fountains used by children in my school were tested. They were found high in lead. The custodian (a school paid employee) was told he needed to figure out how to run ALL the fountains in the building for 10 minutes each day to flush them, Plus we have fountains in some classrooms. Reality? Impossible. Then they ceased to use school employees to be custodians of our schools, instead contracting services. Finally, in the past few years, we have two specially installed, filtered water faucets for our 800+ students. But the others remain. I have always been concerned about the water there, especially when the trend was for children to drink a lot of water each each day, filling water bottles. I know that next year they are slated to install two more filtered systems...but all of those years I worried. And, yes, I mentioned it, many times. Do you think anyone listened?
