What exactly happens behind the scenes for clean, safe drinking water to come out of your kitchen faucet? It turns out, there are marvels of engineering and health science right under our feet, but much of our water and sewer infrastructure in the U.S. is outdated—sometimes dangerously so. In this episode, we hear from University of Rochester Professor Morris Pierce on the history of American water works and Town of Liberty Supervisor Frank DeMayo on how our local drinking water and wastewater systems work, and what the most pressing issues are with them that need to be addressed sooner rather than later.
