I worked the Jonah and Mesa gas fieldsin Wyoming on at pulling unit for 3 years and the fracs for 2 years and never missed a days work.
Something tells me this is BS frenzy to create fear
they have a leak in the basement--in a storage area--or somewhere else where chemicals are stored in the building or a nearby building (more uses for acetone in biology than oil well drilling).
...someone is dumping chemicals into the sewers and the fumes are backing up into the building...
...there is a chemical dump nearby leaking (Love Canal stuff)
...or there is a drug lab in the neighborhood.
Just my guesses.
I have never been on a drilling location (and I have worked on hundreds of them) where acetone was used.
This is all green weenie generated hysteria to spook the public on fracking causing everything from earthquakes to chemical poisoning of water aquifers.
Liberals love to exploit scientific ignorance.
