ABOUT THIS EPISODE
Just how hard is it to keep wastewater out of our drinking water? Super hard. In this episode, we take a look at the lengths one great American city, Chicago, went to in order to keep the source of its drinking water clean. Reverse the flow of the river? Why not? Then we explore the origins of activated sludge — a century-old microbial goo that still cleans up our sewage today. We end with a scientist studying what a city’s wastewater can reveal about the severity of the COVID-19 pandemic.

A pitched legal battle, known as the Water Wars, played out. Some government-run utilities wanted to keep pumping fro…
Older American cities have a dirty problem — outdated sewer systems that use a single pipe to carry both sewage and stormwater to treatment facilities. As population growth and climate change have increased both sewage and stormwater, those pipes can get filled to capacity, and the untreated water …
