North Indian Bend Wash Superfund Site

Public safety agencies and governments can choose from a variety of mission-critical communications providers. They consistently choose Motorola Solutions because we provide exceptional solutions at competitive prices, as well as service and support to ensure those solutions meets our customers’ specific, demanding job requirements.


Our Approach

One remediation effort with which Motorola Solutions is involved is at the North Indian Bend Wash (NIBW) site, an eight square mile study area in Scottsdale, Arizona, U.S., where portions of the underlying groundwater contain volatile organic compounds (VOCs).

Motorola (now Motorola Solutions) has operated in the Phoenix area for more than 50 years. We are managing environmental cleanup related to the former site of the Government Electronics Group located at Hayden and McDowell Roads in Scottsdale. In 1983, the U.S. Environmental Protection Agency (EPA) designated this area as the North Indian Bend Wash Superfund Site following detection of trichloroethylene (TCE) in two public water supply wells. Motorola Solutions, Siemens and GlaxoSmithKline (known as the NIBW Participating Companies) are the principal companies responsible for the NIBW cleanup.

Through 2016, we have spent more than $148 million on environmental cleanup activities at the Scottsdale site. More than 112 billion gallons of water have been pumped and treated at the NIBW site since the cleanup began. 

In 2011, the EPA performed the first five-year review of the site, and concluded that the remedy is protective of human health and the environment, that the remedy is functioning as intended, and that remedial actions are contributing to restoring groundwater for beneficial use.  

The EPA conducted the second five-year review of the site in 2016, which concluded that while the remedy remains protective, the areas in the immediate vicinity of the former soil impacted source areas will need to be re-evaluated for potential vapor intrusion risk due to new standards developed in 2014.  Results of this re-evaluation will be reported in 2018.

In July 2009, we began purchasing renewable energy to power remediation efforts at NIBW sites. All the electricity used at the Central Groundwater Treatment Facility comes from wind farms and 100 percent of the electricity used at the MRTF, NGTF and the Area 7 Groundwater Extraction and Treatment System (GWETS) comes from solar, wind, geothermal, biogas and biomass energy generation. Between July 2009 and December 2016 we purchased approximately 15 million kilowatt hours of renewable energy for NIBW sites
