How commonly do you think that flammable tap water issue occurs outside of anti-fracking propaganda films? Also you're aware that it is an occasionally natural phenomenon, right?
Well water is often naturally pretty nasty even without fracking. I am generally anti-fracking, but take those videos you’ve seen with a grain of salt. Those things happened routinely even before the fracking boom.
There are better criticisms of fracking like the higher rates of disease around well sites, and improper dumping of waste.
