"Any threats posed by the PFAS in the blades and backing of turf add to questions that were already swirling about the crumb rubber sprinkled over it. In 2014, soccer coach Amy Griffin realized that an alarming number of goalkeepers had developed cancer after playing on turf fields and began tallying all the athletes she could find in the same situation. By January 2019, her list included 260 young football, baseball, lacrosse, and soccer players with cancer. Griffin has repeatedly called for more research.
