As for the claim that fracking fluid never gets into the ground water---horse ****. There are spills--and even cases here of dumping spent fluid down abandoned oil wells and into creeks.
Spills and dumping into creeks is not a "normal" practice and the operator should be held responsible for the cleanup. You dont just "dump" fluids down an abandoned well, those are supposed to be cemented up or at least our regulations are enforced that way. There are licensed and monitored "injection wells" that are used to put the produced water that comes out with the oil right back into the ground, but those are injected into the same formation the oil came from. If the oil wasnt in the water zone to begin with, and fresh water(water well) is not going to be coming out of an oil zone, that water is salt water.

If you are having a problem with companies not complying with your rules and regulations, maybe you should elect people to the job that can do the job. Or maybe your state or area needs to look into what is working in other places and structure their laws accordingly. There is no excuse for "accidentally" having a recurring spill, but to require a "tracer" to be added to the fluid is almost ignorant. Do you realize how many barrels of fluid, which is just about all fresh water and some sand it takes to do a job? You would have to add a large amount of chemical to even start to be able to track it and secondly, wouldnt that just be adding to your problem? If they do finally decide to show the chemical makeup of frac water, there are going to be many red faced protesters mulling about, it is not near what the "chicken littles" are making it out to be.

In short you need water to take the sand down to plug into and hold the cracks open that the pumping pressure creates in the formation. The water has a gel mud mixed with it to hold the sand in the water in order to insure that the sand just doesnt fall out and not go back into the formation. As the well is opened up, all of the fluid and some sand that was injected into well comes right back out the top. When the water that was used for the "frac" comes back out it brings oil with it as it comes. When the "frac water" is collected in tanks, they know how much they put in and they know how much they get out. Its not a big "F'n" deal, as the VP Biden says, its a normal process and contrary to some belief the frac crews are not dying in droves from the chemical imbalance in their systems. The cracks from the Fracing, do not go for miles into the surrounding countryside, in fact they might only extend a hundred feet from the center of the well at the most. The other cracks that are allowing the oil and gas to travel underground for centuries have always been there, the frac just opens them up a little to allow freer travel for the oil through the solid rock.

I'll go back to the Waffle house now, at least the sky is not falling there.
