Don’t know if it’s practical to store used frack water and take it to other frack sites for reuse. That would be green wouldn’t it?
My understanding is that is what is normally done. I also have heard that different types of rock require slightly different fracking fluids, thus it may be more practical to send the used fluid for disposal than to store for reuse if the frack uses less common mixes.
Yes. However, first, keep in mind that this "hazardous" stuff is not the fracturing fluid itself, but the salts and other minerals brought up from those depths....in other words, this "hazardous" stuff is made by mother nature.
Second, it is illegal to send it back down again.
Third, the industry is near 100% recycling their frac water. The hazardous stuff is separated and disposed properly based on what it is.
The salts can be used for road de-icing.
The radioactive components (uranium, radon, etc) need to be disposed in specialized ways.
Other wastes can simply be burned in a closed system.
The real point here is that the fluid must all come out of the well before it goes into operation. Frac fluid does not remain underground for any period of time more than a few weeks (at most).
So, all this talk of contamination, migration, etc are all nonsense.
