Protect and Preserve American Fork Canyon requested the EPA come to American Fork Canyon after the Tibble Fork Disaster. The EPA heeded that request and have subsequently created a 300+ page Preliminary Assessment of the heavy metals challenges in AF Canyon. Many of these problems areas originate on private land that has not been mapped, hence the boundaries of these areas are difficult to ascertain. More details, news articles etc. can be found at the PPAFC website.
