Wood Environment & Infrastructure Solutions, Inc. (Wood) was selected for this project to conduct work in support of the per- and polyfluoroalkyl substances (PFAS) program. This project is a multi-phased pilot study to further validate and refine potential locations across Minnesota that may have historically been, or are currently, contaminated with PFAS. The primary objective is to evaluate potential PFAS locations, specifically compost sites, to determine presence or absence of PFAS at each site.
