grhe,
A Marcellus well went in behind my dad's place last year (not his property). It was more like 1 acre that was cleared. Lots more trucks than the old wells, but thankfully the drilling part is over now, and the well itself looks the same as the 10 other wells within a mile radius of his place.
The old wells used the very same frackwater. The difference in Marcellus is that they are deeper, and incorporate horizontal drilling as a way to minimize the increased cost of drilling deeper. As far as spillage concerns, this means there is little difference, as the practices, and rules, for all areas above the water table are unchanged. What happens 5000 feet deep is totally meaningless to the streams. If anything, the fracking going on thousands of feet, instead of hundreds, below the water table lessens the danger of methane seepage from depth into the water table. The danger to the water table is still in the top couple of hundred feet of the drill hole. The drilling companies must properly seal this top area, and failure of the seals results in frackwater contamination or methane contamination of the water supply. But again, this aspect is no different than those old wells. While there were incidents back then, and have been already with the new wells, the overall success of this is statistically good. That doesn't mean they shouldn't improve, if 0.5% of wells leak, but you have thousands of wells, well thats still too many.
Thousands of Marcellus wells aren't that many. Currently, on the ANF itself, there are over 9000 working gas wells, and at least double that many that are no longer functioning. Overall in PA, there are already roughly 80,000 working gas wells, and many more that are no longer working. And these wells are spread over a smaller area than Marcellus looks to take on, so its fair to say the density of Marcellus wells will be considerably lower, which makes sense given the horizontal drilling.
The main difference that I can see, is the vastly increased volume of water used. While the old regulations need to be enforced, this is what leads to "new" issues that need to be addressed:
1. We need to be sure we have a system to effectively govern where and when they can take water. If they take it from a river during the high water of April, no problem. If they take it from a little stream in the low water of August, huge problem!
2. This will place vastly increased demand on treatment plants. We need to make sure the waste is being handled effectively, and increase facilities if needed.
3. This means a lot more trucks will be using our roads and bridges until the new wells are drilled. The drilling companies either should have to help maintain the roads, or at least be forced to reimburse PennDot and the townships.
I'm not claiming that this is a pleasant thing thats going on in our state, or that you shouldn't have any concerns. I just think the doomsday thoughts that entire areas will be totally ruined for outdoor recreation is vastly overplayed. You should be watchful and report anything that looks suspicious. You have the right to be a little upset about whats happening. But your comment that Potter County will become a "wasteland", IMO, is very off base.
