Yes, I was thinking the same thing. 1% is actually an enormous amount since toxins are measured in ppm. Imagine being asked, for every 100 cups of water you drink, to drink a cup of mystery fluid. Actually, it's worse because any (non volatile) additive will tend to concentrate over time in food (and then concentrate further in animals if the food used for feed), and in addition any chemical is bound to change over time in contact with sunlight and ordinary plant/animal biochemistry.

I've never heard of this use of fracking water in CA, and if it's real it sounds to me like frackers IP be damned, we need to know what's in the damn water!
