Formation of chloroform during disinfection of drinking water has been known for a long time and is correlated to the total organic loading of the water. This means we are making the Chloroform [CHCl3] when we treat the water with chlorine. No amount of control on CHCl3 emissions will change the problem as long as we use chlorine to treat water.
This detail confounded the EPA lawyers for years and still may. The organics that make CHCl3 on chlorination need only have a methyl ketone moiety present. These are common in nature but can be from any source, natural or anthropogenic. All will produce chloroform on chlorination. The reaction is well known to basic organic chemistry students and is called the "haloform reaction" as it works with bromine also.
I backtracked an old reference should anyone want to read it. The first page is available for viewing without charge at pubs.acs.org... but your local college library should have the complete paper in their stacks.

I agree. When I lived in California, didnt worry one bit about Fracking. No significant shale to speak of. However, I just moved to Houston, Texas; near two small but substantial shale deposits. Luckily because I live in an urban area my water source is not from the ground, however it still worries me.
I honestly feel like these candidates live in an alternate reality where Fracking has no environmental consequences, we can make colonies on the moon, and God only knows whats next.
