Had a mapping job to do in PA a while ago and saw multiple drill sites on the aerial imagery; a support staging area an acre or two in size was lined with with an impermeable engineering membrane.

In my limited time in the industry, there was no acetone used for anything that I recall.
Well, take that back - maybe for cleaning Sharpie grafitti off the break room tables ?

Avg. water table is ~50-100' down.
Avg. frac depth in PA, below impermeable shield rock, is usually => ~1,000 ft down.

Chances of fracking causing groundwater contamination are about 0.
That doesn't rule out foul-ups up top, but most of the site bosses are (rightly) nazis about keepin' the sh!t together.

Smart money will always bet on hysteria/agendas behind unicorn farts like this article.
