The Verona Well Field Superfund site has three source areas: Thomas Solvent Raymond Road, Thomas Solvent Annex and the Paint Shop. Thomas Solvent Raymond Road is located on Raymond Road and was used from the 1960s to the 1980s for storage and packaging of solvents. Spills from the operations, along with leaks from underground storage tanks, resulted in soil and groundwater contamination in the area from volatile organic compounds. Cleanup activities to address the VOCs included installation of a groundwater pump-and-treat system and installation of a soil vapor extraction/air sparge system. The Thomas Solvent Annex source area is located on Emmett Street. Soil and groundwater were contaminated by the Thomas Solvent Company through the handling, transportation, storage and disposal of solvents. Cleanup activities to address the VOCs included installation of a groundwater extraction system, installation of a soil vapor extraction system, and installation of an air sparge system. The Paint Shop source area is located near the railroad yard. Soil and groundwater became contaminated through improper disposal of spent solvent.
Cleanup activities to address the VOCs included limited operation of an air sparge system. Contaminated groundwater from the three source areas migrated to the Verona Well Field, which is the primary well field for potable water for the city of Battle Creek. The Verona Well Field is protected by a series of extraction wells that capture contaminated groundwater before reaching the municipal water supply. In November 2025, EGLE sampled for PFAS in five of the groundwater monitoring wells at Thomas Solvent Raymond Road. All five wells exceeded criteria, the highest of which had 60 ppt PFOA (compared to 8 ppt), 37 ppt PFOS (compared to 16 ppt) and 240 ppt PFHxS (compared to 51 ppt). In January 2026 EGLE received the results of groundwater sampling at Thomas Solvent Annex and the Paint Shop. Seven groundwater monitoring wells were sampled at the Thomas Solvent Annex source area. All seven wells exceeded criteria, the highest of which had 34 ppt PFOA (compared to 8 ppt) and 65 ppt PFOS (compared to 16). At the Paint Shop Source area, only one of five groundwater monitoring wells exceeded criteria with one detection pf 8.4 ppt PFOA (compared to 8 ppt).

EGLE, DHHS, and local health have reviewed residential well logs and are developing a plan to sample nearby drinking water wells. In late winter, early spring 2026, identified well owner(s) will be sent a letter requesting access to sample drinking water.
