The 3.5-acre H. Brown, Co., Inc. site is located in Walker, Michigan. The site is an inactive automobile and forklift battery recycling facility with about 200,000 cubic yards of soil contaminated by lead and other battery-related metals. The site and surrounding area may have been used as a municipal waste disposal landfill before the H. Brown Company began operating on site in 1961. Waste disposal and lead reclamation processes contaminated air, groundwater and soil with lead and volatile organic compounds (VOCs). Following cleanup, operation and maintenance activities are ongoing.
