Dr. Kris Rolfhus is a Chemistry & Biochemistry Professor at UW-La Crosse where he leads a team of student researchers focused on collecting vital data about the safety of play surfaces and the possibility of children ingesting trace metals such as lead while at play.

They collaborate with community members through SPACE and Thriving Earth Exchange and conducted Citizen Science during Earth Fair which allowed for community participation in the sampling process.

The group's goal is to provide valuable insights that promote safer playgrounds and protect the well-being of children in our communities.
