Environmental concerns being addressed at industrial site

Corina Vanek

Arizona Republic USA TODAY NETWORK

After Onsemi announced it would move its headquarters to Scottsdale, the company formerly known as ON Semiconductor sold its Phoenix building to a developer that plans to find an industrial user for the site.

Developing the site at 52nd Street and McDowell Road includes contending with the ongoing environmental cleanup of contaminated groundwater that dates back to when the site was used by Motorola. Onsemi is a spinoff company of Motorola and began operating independently in 1999.
