Little known fact: high concentration of TCE permeates the Bay Area in cites like Palo Alto and Mountain View. The concentration is so bad that these superfund sites are regularly monitored by the federal government.[1]

I lived next to the superfund site of Palo Alto, which was right under Mayfield Soccer Complex. Little had been done to monitor the risks for the children [2]. Reading this article linking TCE to Parkinson's disease, I hope there will be more awareness about Silicon Valley toxic undergrounds.
