About this file

This document is a Landfill Fact Sheet for the City of Phoenix, detailing seven different landfill sites across various locations in Arizona. The landfills are spread across different council districts, with sizes ranging from 14 to 2,654 acres, and were opened between 1946 and 2006. All landfills are currently closed, with their opening and closing years documented. Each site has unique characteristics, including total refuse buried ranging from 2.5 to 19.5 million tons, and refuse capacities between 4.0 and 39.9 million tons approximate.

The landfills employ similar waste management technologies, including landfill gas collection systems using flare systems, with 19th Avenue Cell A featuring an activated carbon capture method. Groundwater monitoring frequencies vary from none to quarterly, with most sites conducting semi-annual monitoring. Future end uses for these sites include potential park areas, radio towers, and a golf course. The landfills have varying numbers of landfill gas (LFG) wells, probes, and sumps, indicating different stages of environmental management and closure. The fact sheet is updated through fiscal years 2024-2025, providing a comprehensive overview of the City of Phoenix's landfill infrastructure.
