You’ll hear why environmental testing for chromium did not specifically look for hexavalent chromium, or chromium 6, and why scientists, residents, and public officials are still asking whether it is worth looking now. As Season 3 begins, we follow new questions about environmental testing, health concerns, and what may still be possible to learn about the chemical plume that spread across metro Atlanta.
