"The sausage-shaped ingots were then shaved into thin wafers, and polished using a number of chemicals. After that came the process of printing transistors into the chips–which required degreasers and solvents, including the sweet-smelling trichloroethylene (TCE)"


I did not say that silicon wafer manufacture did not use chemicals which, if released, would cause a problem.  

The first article below deals with events at least as far back as the 1950's.  Practices were different then.    The article refers to TCE, but one major source of chlorinated solvents was dry-cleaning plants.  

Can people point to modern wafer-fabs as being a source of this kind of pollution?




"The sausage-shaped ingots were then shaved into thin wafers, and polished using a number of chemicals. After that came the process of printing transistors into the chips–which required degreasers and solvents, including the sweet-smelling trichloroethylene (TCE), which was only classified as a carcinogen by the EPA in 2005 and would later be found in groundwater around Silicon Valley after leaking from dozens of different manufacturing sites. TCE, which was first made in the US in the 1920s, has been used at various points in history as an engine parts degreaser and as an alternative to chloroform."

Notice "dozens of different manufacturing sites".  Were any one of the polluting sites silicon wafer fabs?



Air pollution.  Nothing at all due to silicon wafer fabs.


I've separated out the headlines.  I can't see a reference to silicon wafer fabs.   

Baykeeper's Legal Action to Clean Up Industrial Runoff Pollution

When Congress passed the Clean Water Act, they included a citizen suit provision that allows citizens and citizen groups like Baykeeper to bring a lawsuit against a polluter in order to enforce the law when state and federal regulators do not. Congress specifically provided this tool so that citizens and citizen groups—not just regulators—would have the power to ensure that polluters follow the law.
With California's enforcement agencies drastically underfunded, Baykeeper plays a critical role in enforcing the Clean Water Act to control industrial storm water pollution. Baykeeper has a long history of successful Clean Water Act litigation to reduce industrial storm water pollution in San Francisco Bay. Our staff has the legal and scientific expertise to research and identify which facilities need to be cleaned up, recommend appropriate improvements and secure legally-binding agreements to effectively reduce toxic pollution.
