      Yes, a real mess. The plant was build by Rockwell Automation/Allen-Bradley in 1969. MOS used concrete storage tanks until 1975 for production waste, and then unlined steel tanks. Both apparently leaked into the surrounding groundwater.

      Here's the EPA page on it:

      Photos taken recently as I was passing through of the old fab building in the Valley Forge Corporate Center, Norristown PA.

      It was last occupied by GMT some time ago.
      Wiki info below talks about EPA problems shut it down.
      We often joked that it must be a mess there
      but I didn't know it was an EPA disaster in earnest.
      Explains why that corp park had problems through the late
      90s and beyond.

      GMT Microelectronics

      After Commodore's bankruptcy in 1994, Commodore Semiconductor Group, MOS's successor, was bought by its former management for about $4.3 million, plus an additional $1 million to cover miscellaneous expenses including EPA liens. Dennis Peasenell became CEO. In December 1994, EPA entered into a Prospective Purchase Agreement (limiting the company's liability in exchange for sharing the costs of cleanup) with GMT Microelectronics. In 1995, the company, operating under the name GMT Microelectronics (Great Mixed-signal Technologies), reopened MOS Technologies' original, circa-1970 one-micrometre fab in Norristown, Montgomery County, Pennsylvania that Commodore had closed in 1992. GMT would have provided foundry services based on TelCom's Bipolar and SiCr Thin Film Resistor processes and would have been licensed alternate sources for TelCom's Bipolar based products. With production running at 10000 wafers (size 5) per month, producing CMOS BiCMOS NMOS BIPOLAR SOI. The plant had been on the EPA's National Priorities List of hazardous waste sites since 1989. By 1999 it had $21 million in revenues and 183 employees, within 3 years. However, in 2001 the EPA shut the plant down due to the leaking of their underground hazardous waste storage tanks. The leaks from these tanks caused the local groundwater to become contaminated with trichloroethylene (TCE) and other volatile organic compounds (VOCs). GMT ceased operations and was liquidated.
