Thank you very much, Mr. Chairman.
Again, thank you to our witnesses.
My first question is to Professor Ingraffea.
You've given us a really comprehensive characterization of both the flowback and the chemicals that remain in the ground, which are part of the hydraulic fracking process. I can only infer that the level of uncertainty about matching that issue--not to mention the propane, methane, and other chemicals and gases that are created--has given the State of New York cause to take a step back and have a look at it.
Can you give us any insights on the level of technology and the research that exists, in terms of now getting an opportunity from this moratorium to match the degree of uncertainty and risk with technology that can counterbalance that? Are you aware of what is happening, and can you share that with the committee?
