350 ELLIS ST

Raytheon Company. formerly operated as a semiconductor products manufacturer at 350 Ellis Street on this 30-acre property in Mountain View, California. The Raytheon site is one of three Superfund or National Priorities List (NPL) sites that are being cleaned up simultaneously. The other two Superfund sites are the Fairchild Semiconductor Corp - Mountain View site and the Intel - Mountain View site. All three sites are located in the Middlefield-Ellis-Whisman (MEW) Study Area and are being addressed collectively as the MEW SIte. Site investigations at several of these facilities during 1981 and 1982 revealed extensive soil and groundwater contamination, primarily volatile organic compounds (VOCs). The primary causes of the contamination were leaking storage tanks and lines and poor facility management practices.
