I figured I would post this in this forum since an issue like this obviously relates to policymaking.
The subject is a matter for study....

Contaminants of concern to drinking water include fracturing fluid chemicals and degradation products and naturally occurring materials in the geologic formation (e.g. metals, radionuclides) that are mobilized and brought to the surface during the hydraulic fracturing process.
There are plenty of people worried...

Coal seam gas mining can cause cancer and harm unborn children, a group of medical experts have warned.
The six experts, who include a Queensland government epidemiologist, say the state's ban on the use of cancer-causing chemicals collectively known as BTEX in CSG mining doesn't protect the community from health risks.
BTEX chemicals have been used in hydraulic fracturing, known as fracking, in the United States and other parts of the world to crack the coal seams and extract the natural gas.
But in a submission to a Senate inquiry into CSG impacts, which is sitting in Queensland this week, the microbiology and disease experts say BTEX exists in the coal seams.

'BTEX chemicals (benzene, toluene, ethylbenzene and xylene) are frequently found together in petroleum compounds,' the submission says. They are in a class of chemicals known as volatile organic compounds which easily vaporise so people can be exposed through drinking water, bathing or breathing in vapour.
The French have banned fracking...

The French parliament voted on June 30 to ban the controversial technique for extracting natural gas from shale rock deposits known as hydraulic fracturing, or fracking, the web sites of Le Monde and other French media reported.
But probably most conclusive is Halliburton thinks there's no problem.
