Marengo County Sanitary Landfill - Linden, Alabama Solid Waste Management Facility

Marengo County Sanitary Landfill is an operational landfill located in Linden, Alabama, United States. It is classified under NAICS code 562212 (Solid Waste Landfill) and serves as a municipal solid waste disposal facility for Marengo County and surrounding areas. The landfill is situated in a rural region of western Alabama, approximately 30 miles south of Demopolis. As a Subtitle D landfill under the US EPA's Resource Conservation and Recovery Act (RCRA), the facility must comply with federal standards for liner systems, leachate collection, groundwater monitoring, and landfill gas management. Alabama's solid waste regulations, enforced by the Alabama Department of Environmental Management (ADEM), align with these federal requirements. The landfill likely operates with a composite liner, leachate collection system, and gas monitoring to mitigate environmental impacts. The facility plays a critical role in managing the region's solid waste, reducing illegal dumping, and supporting public health. Its location in a rural area with lower population density may reduce community proximity risks, but groundwater protection remains a priority due to the potential for leachate migration. Proper operation and monitoring are essential to minimize methane emissions and protect local water resources.

The landfill is located in a rural area of Alabama with a humid subtropical climate, receiving significant rainfall that increases leachate generation. Groundwater protection is a key concern, as the facility must manage leachate to prevent contamination of local aquifers. Landfill gas, primarily methane, is generated from decomposing waste; while gas collection may be implemented, uncollected methane contributes to greenhouse gas emissions. Community proximity is relatively low due to the rural setting, reducing traffic and odor impacts, but monitoring remains essential.
