This just the beginning. The drillers have no idea what they are doing down below. They have very little idea of all the formations they are drilling through. They absolutely have no control over the venting of the gas. And yes, they need to disclose, recover and retain all of the high pressure fluids that they use.

Federal environmental regulators say they will develop national standards for the disposal of polluted wastewaters generated by hydraulic fracturing for natural gas. The agency said it will draft standards for fracking wastewater that drillers would have to meet before sending it to treatment plants.
“Fracking” as it is commonly referred to is used extensively in natural gas extraction throughout the United States, including Colorado and neighboring Wyoming. It has been the main technique for freeing up large pockets of shale gas deep underground, and involves injecting sand and chemical additives mixed with millions of gallons of water. The potential impact on water quality in the areas where fracking is practiced is the main concern, although the industry points out there have not been any documented cases of water supplies being contaminated, and hydraulic fracturing operations take place far below water tables.

Major natural gas companies like Encana Oil & Gas (USA) Inc., which has a major presence in Colorado, and Chesapeake Energy recycle a large percentage of fracking wastewater, other operators inject it underground. However, a certain amount is sent to treatment plants that are not equipped to handle it.
