happens in Pa. It's not rare either
I thought that was from methane coalbeds? and all those old wells drilled before 1930? Also, what about their disposal methods when they dispose of the used water back into old formations? Water is disposed of back into older wells, frac water included. The formations fracced are to be under impermeable rock, but they have to dispose of the water that is pumped out of the fracced well. If they dispose of that water unsafely, then you get contamination, likely the culprit in PA since they have little regulation of disposal wells, not to mention all the other industries that dispose of waste water laden with chemicals into those old shallow formations.
After a frac job, the water used in the frac is recovered (flowed or swabbed) through the well bore to the surface, put in tanks and then disposed of down another wellbore used for water disposal. Please do not get me wrong here, I am not for contaminating people's water. But you all need to understand what really happens with disposal and the frac process before you consider yourselves educated on the topic. It is easy to blame the fracturing because it is new and misunderstood, but oil has been prduced in PA since 1900, when there was no regulation and those old wellbores are pitiful. Those old well bores are used for disposal and they probably should not be. Get some regulation and disposal and fracturing wells can be safe. There is alot going on here, and it is not just fracturing wells.
