In the spring of 2015, Dr. Eric Roy received word from a former Environmental Protection Agency (EPA) member regarding elevated lead levels in Flint, Michigan's water. At that time, the residents of Flint were unaware of the water's contents and long before the city faced a public health emergency.

Roy, a chemist specializing in water quality, took it upon himself to address the issue. In July 2015, he established Hydroviv and devised a high-capacity lead filter for Flint. Working from his studio apartment in Washington, D.C., Roy and a friend conducted pressure and leak tests, as well as prototyping for the first Hydroviv filter. With their lab set up in a bathroom sink, he shipped the inaugural filter to a children's organization in Flint just two months later, after locating them through social media.

Roy also shares a lot of content on PFAS, so he joins the podcast to discuss why some states have protections, and others don’t.
