Former Keeler Brass - Godfrey Ave (Grand Rapids, Kent County)

EGLE Site Lead: Peter Van Heest, or 616-439-8019. Webpage last updated November 12, 2020.


The Former Keeler Brass – Godfrey Avenue plant located at 955 and 945 Godfrey Avenue SW, operated from circa 1902 to 2007. The former plant is in an industrial corridor in the City of Grand Rapids. Past operations at this plant included a foundry and metal plating. Previous sampling had detected high levels of chlorinated volatile organic compounds and other contaminants in the sub-surface at this site. Due to the history of metal plating at this site, EGLE collected groundwater samples for PFAS analysis from three existing monitoring wells on the property in August 2020.

Groundwater flow has not been measured but is estimated to flow roughly along Godfrey Ave. and north towards the Grand River.
