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.
