Wickenburg MSW Landfill - Municipal Solid Waste Landfill in Wickenburg, Arizona

Wickenburg MSW Landfill is an operational municipal solid waste landfill located in Wickenburg, Arizona, approximately 4.6 miles west of the intersection of US 60 and AZ 89. The facility serves the local community and is part of the solid waste management infrastructure in Maricopa County. As a landfill operating in the United States, this facility is subject to federal regulations under the Resource Conservation and Recovery Act (RCRA) Subtitle D, which governs municipal solid waste landfills. Additionally, Clean Air Act regulations apply to landfill gas management, requiring gas collection and control systems for larger landfills. The facility's NAICS code 562212 indicates it is classified as a solid waste landfill. The landfill plays a key role in managing waste from the Wickenburg area and surrounding communities. Its location in the arid Arizona climate influences leachate management and groundwater monitoring requirements. Proper operation helps mitigate environmental impacts such as methane emissions and groundwater contamination risks.

The landfill operates in a semi-arid region of Arizona, where low rainfall reduces leachate generation but increases dust and windblown litter concerns. Groundwater protection is critical due to the proximity of the Hassayampa River and local aquifers. Methane generation from decomposing waste requires gas monitoring and potential collection systems to reduce greenhouse gas emissions and comply with Clean Air Act standards.
