Shredded tire mulch: Soft and safe or dirty and dangerous?
This Eyewitness News report from July covers the controversy of shredded tire mulch on playgrounds in Duluth. Cory Kirsling, father of a Lester Park Elementary School student, has started a GoFundMe page to raise money to have the mulch tested “for heavy metals, VOCs, off-gassing and leaching, toxins and carcinogens.” His page notes, “a local lab will collect the samples from our school’s playground, and we will share the research with everyone.”
