The Irvington Landfill is located on the south side of Irvington Rd a quarter of a mile west of Houghton Rd. This landfill was used for the disposal of municipal solid waste. Today the City monitors fourteen shallow landfill gas probes, one nested deep soil vapor well, and four groundwater monitoring wells around the landfill as part of the Arizona Department of Environmental Quality’s (ADEQ) Aquifer Protection Permit (APP). The landfill is owned and maintained by the City of Tucson.
