Well this is some news for concern.  I'm not sure if anyone in Irvine knows about this, but TCE is a toxic contaminant that was used at the EL-Toro Base.  This video tells us that TCE has permeated through out the city of Irvine and has put us all in risk of Cancer and other health problems.  You can actually go to the library and get all the information.  

Here is the story, please let me know if you have any more information on this!
