Good luck getting a penny in compensation out of the corporations responsible if this happens.
They are already smart enough to use shell corporations to do the drilling -- by the time water contamination or triggered earthquakes are discovered, the shell company is long done and a new one has taken its place.
There is plenty of blame to go around. Townships, Counties, States, Cities, all require permits and licensing of some kind before drilling begins and they are supposed to monitor said drilling. Hell, I can't cut down one sapling on my own property without permits from the county and state (proximity to water). The purpose of the permits is to limit and control land/water usage (regardless of property ownership rights). So if you want to blame anyone, start with the ones issuing the permits.
