dorothy felix isn't giving up. >> i will stay with this fight so my granddaughter, if she chooses to live in this community, will have a safe place to live, safe environment. >> here's what felix and others specifically want. that residents who want to leave should be relocated, and those who do stay, should get free health care from the government or industry. >> it may be going forward, we may need to be thinking about locations of industrial facilities and locations where people live and keeping a healthy distance between them. >> are we going to find out 40, 50 years from now some things we thought were safe are in fact more dangerous than we thought? >> we may well. >> that's scary. you hear so much dogma coming from folks from the environmental protection agency, this is fine, don't worry about it. it's safe. as science changes, it may not be, as with lead. >> as time goes on, we get better and better at appreciating the effects of chemical exposure and led us to lower acceptable levels of many chemicals including lead. >> you can't prove the cause and effect relationship here.
