What does it feel like? Does it just tug on your fingertips? Does a strong AC field make it 'buzz'?

Damn you. I've been looking all day for an opportunity to use that line.

Petroleum engineer here.

First off, the three sources you cited are all press reports done on the very same EPA/USGS study, which means you have one source, not three.

That study was done in Wyoming in an aquifer system that has been documented for decades to already naturally contain methane and other petroleum. The water in some formations is so bad, according to a 1969 USGS study, it's "...generally unsuitable for domestic use, and in some wells it is so unpalatable that stock will not drink it." Also, the current EPA study says that there is no water well used by residents that has any contamination. The contamination was found by deeper test wells the EPA drilled into the "unpalatable zone". Furthermore, according to the same report,

the existing data at this time do not establish a definitive link between deep and shallow contamination of the aquifer.

To be fair, it seems some of the chemicals have migrated from the producing zone to an aquifer zone. Keep in mind that there are natural aquifers underneath you right now that would likely kill you if you took a big drink. But as a petroleum engineer, I think Encana is being irresponsible. The shallow wells in Wyoming are as shallow as 1200'. There are drinking water wells in the area as deep as 800'. This particular situation should be watched carefully, and these guys should be prosecuted if anything happens to any water wells. However, this is extremely atypical of the fracking practice. Most wells are at least 8000' deep and protected by 3-4 concentric layers of concrete and steel casing.

Because the people funding the GND-pushers will profit from every form of renewable except nuclear.
