There's been a lot of talk here about the hydraulic fracturing process and the use of unknown chemicals therein. Gas drillers will tell you that fracking fluid is about 98 percent water, so there's no need to worry about the heavily diluted chemicals. However, the average frack job used somewhere between 3 and 5 million gallons of water. When you do the math, that's a lot of chemicals.
Before they're injected in the ground, they have to be stored somewhere. This poor guy in Pennsylvania has some stored close to his home where his 4 year-old daughter plays in the backyard. There are about 20 kids in the neighborhood. There are, of course, some regulatory issues involved. Who regulates small amounts of stored chemicals? In PA it's unclear, and I'm sure it's the same story for Arkansas.
