Secondly while not an opponent to fracking I do think we need to keep studying more wells and make sure we aren't going to ruin our own water supplies. I can walk to work if I have to I can't drink poisoned water
But fracking isn't what you should be worried about.
The gas station around the corner, or the leaky septic system your neighbor abandoned 20 years ago, the illegal dumper down the dead end road, or even the city sewerage plant are all MUCH, MUCH, MUCH greater dangers and more present higher probable risks to contaminating your drinking water.
And you should be weary of those playing upon your fears...

i'm not overly worried about it but it's worth being sure of so investigate away and when we've got all the evidence that fracking isn't bad then there shouldn't be debate anymore.
Forty percent of fracked wells have issues, so 1 study on 1 well means nothing.
I know. I said "control" not seeping. Point is a mile or two of bedrock is a pretty solid barrier to ground water intrusion, no?
Drilling fluids tagged with unique markers were injected more than 8,000 feet below the surface, but were not detected in a monitoring zone 3,000 feet higher. That means the potentially dangerous substances stayed about a mile away from drinking water supplies.
"This is good news," said Duke University scientist Rob Jackson, who was not involved with the study. He called it a "useful and important approach" to monitoring fracking

This is one well.
The study, done by the National Energy Technology Laboratory in Pittsburgh, marked the first time that a drilling company let government scientists inject special tracers into the fracking fluid and then continue regular monitoring to see whether it spread toward drinking water sources. The research is being done at a drilling site in Greene County, which is southwest of Pittsburgh and adjacent to West Virginia. Eight new Marcellus Shale horizontal wells were monitored seismically and one was injected with four different man-made tracers at different stages of the fracking process, which involves setting off small explosions to break the rock apart. The scientists also monitored a separate series of older gas wells that are about 3,000 feet above the Marcellus to see if the fracking fluid reached up to them.
there aren't companies out there just running wild poking holes in the ground as fast as they can with no consideration as to how long the casing may be able to stand up to the conditions it will experience over the life of the well.
I am in favor of sufficient FedGov oversight and regulation to PREVENT these kinds of destructive practices.
