The Michigan EGLE recently added Harbor Island in Grand Haven to their list of PFAS sites. The Grand Haven site is a natural marshland at the mouth of the Grand River as it flows into Lake Michigan. The site was first used as a landing point for logging operations. During the 1950s and 1960s the site was used as a dump. The coal-fired J.B. Sims Generating Station began operating in the early 1960s by the Grand Haven Board of Light and Power (GHBLP). Coal ash wastes were disposed of in unlined lagoons and the adjacent wetlands. In the early 1980s, clay lined lagoons were constructed for coal ash management.
