The 12-acre Union Chemical Company, Inc. site is located in South Hope, Maine. The Union Chemical Company began operations on site in 1967, formulating paint and coating strippers. In 1969, the company expanded its operations and began handling and recovering petrochemical-based solvents. In 1976, the company received a state permit for an underground disposal system (a septic system) for its process wastewater. On-site soil and groundwater contamination resulted from a combination of leaking stored drums and spills, and the use of the permitted septic system for disposal of the process wastewater. Following the removal of contaminated drums, tanks and soil, groundwater monitoring is ongoing. No further response actions are planned.
