About this file

The document is a Landfill Fact Sheet for the City of Phoenix, detailing seven landfill sites across different locations in Arizona. The landfills range in size from 14 to 2,654 acres, with opening years spanning from 1946 to 2006. All listed landfills are currently closed, with the SR 85 landfill being the most recently opened (January 2, 2006) and still active. Each site has varying characteristics, including different refuse burial amounts ranging from 2.5 million to 19.5 million tons, and are located in different council districts around the Phoenix area.

The landfills employ similar environmental monitoring techniques, with most using flare systems for landfill gas collection and conducting semi-annual or quarterly groundwater monitoring. The 19th Avenue Cell A site is unique, being a Superfund site de-listed in September 2006 with no planned future use. End-use plans for other sites include potential park areas, radio towers, and a golf course. The landfills vary in their number of landfill gas (LFG) wells, probes, and sumps, with the Skunk Creek location having the most extensive infrastructure with 268 LFG wells, 45 probes, and 102 sumps.
