Fracking also contaminates groundwater with chemicals that they won’t tell what they are. On that basis alone it should be banned.

I don't believe it..

The article is three years old. Here’s the actual USGS report:

So far as “finally admitting”. I don’t know how fair that headline is. Until there was enough data to study probably no one knew the connection. The role of the geologists at USGS is to study and report. If there is any admitting to be done I’d think it would be by the oil companies.

The observation at the time was that fracking-caused earthquakes were declining. Part of that decline might be that whatever potential energy was stored underground had already been released through the injection of wastewater. Think of an avalanche. Once it’s over it’s over for a period.

Thanks USGS>. is like Captain Obvious.
