After Rhinelander Mayor Chris Frederickson found out in 2019 that at least one of his city’s municipal water wells was contaminated with a dangerous compound, he got in touch with Jim Tinjum.
Tinjum is an associate professor at the University of Wisconsin-Madison. He also heads the geological engineering program, which is how Frederickson found him.
“I was contacted to help them figure out where the PFAS was coming from and what to do about it,” Tinjum said.
