Some say it's better corrosion control. Others say it's getting lead service lines out of the system altogether. But many observers agree that current federal regulations are totally inadequate.
Some fancy science, that's what. As in some inductively coupled plasma optical emission spectroscopy — a process that can analyze samples quickly and with super-accurate results.
A PublicSource investigation digs into which Allegheny County schools are testing for environmental toxins, how often they're testing, and what steps they’re taking to correct problems.
After tests showed lead levels exceeding federal limits, the state is requiring Pittsburgh to replace its old lead water pipes. But just how much that will cost and how long it will take is anybody's guess.
