I felt terrible about the people effected by those superfund sites. My previous career was all about cleaning up the environment, I miss my old job sometimes. I helped remove and cleanup a lot of toxic soil and other hazardous waste, it made me feel good every day when I went to work. At the same time, I didn't realize how badly these chemicals were effecting the people that lived near the contaminated sites.
I tried out the EPA website mentioned in the book to look up chemicals in the places I have lived...
