EPA is holding a number of webinars/updates on various issues, including updates on their ongoing Study of Hydraulic Fracturing. Recordings of the events are accessible here. A recent one on fracking is here.
There’s a live one on hydraulic fracturing going on right now, but I can’t seem to log into it. I did manage to type into the questions/comments window a couple of items: one asking whether EPA can move more proactively into the arena of benign fracking compounds, and another on adding a tracer to all fracking fluid mixtures, so we can see what we shall see even decades later. We’ll see what responses ensue, if any.
