5005 E MCDOWELL RD

The Motorola, Inc. (52nd Street Plant) Superfund Site (Site) is a large area of contaminated groundwater extending from the former Motorola facility and other sources. The responsible parties have operated various soil gas and interim groundwater treatment systems since the early 90’s that have reduced contamination. In addition, vapor intrusion mitigation has been installed at 15 homes. EPA and Arizona Department of Environmental Quality (ADEQ) are working to develop final cleanup actions over the next few years. The Site is located in Phoenix, Arizona, generally between 52nd Street on the east, Palm Lane on the north, 7th Avenue on the west, and Buckeye Road on the south. Because of the size of the site, it has been divided into three areas called Operable Units (OUs) in order to better manage the cleanup efforts (click here to see Site Map). ADEQ is the lead agency for activities in OU1 and OU2 with the exception of the vapor intrusion/indoor air investigation in OU1 and OU2. EPA is the lead agency for OU 3.
