Arbor Hills Landfill - Northville, Michigan Solid Waste Management Facility

Arbor Hills Landfill is a municipal solid waste landfill located at 10690 W. Six Mile Road in Northville, Michigan, within Washtenaw County. Owned and operated by GFL Environmental USA Inc., the facility has been operational since 1970 and is projected to close in 2028. As a major landfill in the region, it serves the waste management needs of surrounding communities in southeastern Michigan. The landfill operates under the regulatory framework of the U.S. Environmental Protection Agency's Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs municipal solid waste landfills. This includes requirements for liners, leachate collection and treatment, groundwater monitoring, and landfill gas management. The facility likely employs modern engineering controls to mitigate environmental impacts, such as gas collection systems to capture methane for energy recovery or flaring. Arbor Hills Landfill plays a significant role in the regional waste management infrastructure, handling substantial tonnages of waste annually. Its proximity to the Detroit metropolitan area underscores its importance in managing urban waste streams. The facility's closure plan in 2028 will involve capping and long-term monitoring to ensure environmental protection, including continued leachate and gas management.

The landfill is situated in a region with a temperate climate and significant annual precipitation, which increases the potential for leachate generation. Groundwater protection is a key concern, as the facility overlies the Huron River watershed. Landfill gas, primarily methane, is a byproduct of decomposition; proper collection and utilization are critical to reduce greenhouse gas emissions. The site's location near residential areas in Northville also necessitates careful management of odor, traffic, and litter to minimize community impacts.
