The Bridgeton Sanitary Landfill is one of several former waste disposal areas located within the 200-acre West Lake Landfill site, located at 13570 St. Charles Rock Road, in Bridgeton. Past activities at the West Lake Landfill site include mining limestone and landfilling industrial wastes, demolition debris and municipal solid waste. The Bridgeton Landfill, which was initially permitted on Nov. 18, 1985, accepted municipal solid waste. The waste is located in two distinct areas known as the North and South Quarries. The Bridgeton Landfill stopped accepting waste on Dec. 31, 2004, as the result of an agreement with the City of St. Louis to reduce the potential harm to airport operations from birds that may be attracted to a sanitary landfill. The Bridgeton landfill waste mass encompasses approximately 52 acres, with approximately 240 feet below the ground’s surface and a total waste thickness of 320 feet. The site boundaries are noted on the West Lake Landfill National Priority List Site map.

The U.S. Environmental Protection Agency (EPA) is currently conducting a site investigation and cleanup at the West Lake Landfill site. Each of the former waste disposal areas have contamination characteristics unique to that area. In order to address contamination more effectively, EPA divided the West Lake site into three distinct operable units (OUs). The Bridgeton Landfill is one of three former waste disposal areas that make up OU-2. EPA deferred two former waste disposal areas, including the Bridgeton Sanitary Landfill, to the department for oversight under state regulatory authority. The department’s Waste Management Program oversees closure and post-closure of these former waste disposal areas. The department’s Federal Facilities section is assisting EPA with oversite of the remaining areas in the West Lake Landfill site, due to contamination from materials from the Hazelwood Interim Storage Site that were landfilled in OU-1.

Bridgeton Landfill Events

The Bridgeton Sanitary Landfill currently is owned by Bridgeton Landfill LLC and is a subsidiary of Republic Services Inc. On Dec. 23, 2010, Republic Services reported to the department's Waste Management Program that the landfill was experiencing elevated temperatures on some gas extraction wells. Since that time, a subsurface smoldering event has enveloped much of the South Quarry, as evidenced by rapid settlement an increase in odors and leachate production. Over the years, the landfill owner has been required to implement corrective actions to control and manage the landfill gas emissions (odors) and leachate production from the rapid waste decomposition. Currently, the Bridgeton Sanitary Landfill is in a managed state. As required by a Consent Judgment, signed June 29, 2018, the landfill owner will continue operating, monitoring and maintaining the landfill infrastructure. Data collected under the consent judgment monitoring requirements shows the overall magnitude of the subsurface smoldering event is continuing to slowly decrease. For details about this subsurface reaction event and other events and monitoring that have occurred at the landfill since1992, visit Bridgeton Site Background.
