Stereo Chemistry

Jun 6, 2023

When two wastewater treatment facilities in Baltimore, Maryland, broke down in early 2021, the surrounding waterways began filling up with sewage. In this episode of Stereo Chemistry, C&EN business reporter Craig Bettenhausen takes the pod to visit the Back River Plant and Patapsco Plant in the Chesapeake Bay watershed to demystify how these facilities treat wastewater and take a deep dive into the chemistry behind enhanced nutrient removal systems. Chemical engineers, environmental advocates, and infrastructure experts explore what happens to aquatic ecosystems when wastewater treatment systems fail–and share their perspectives on reimagining wastewater as a chemical treasure trove in the future.
