FYI, that is the southern hills aquifer recharge zone. Southern Hills aquifer being where BR gets its water from. I'm not saying fracking is the devil, but I am saying that all activities above and below ground in a vital aquifer recharge zone should be carefully thought out.
what's the depth of that aquifer? fracks occur 10-20 thousand feet below the ground.
that's 2-4 miles below ground for those playing at home.

If I'm not mistaken, the whet wells that produce Baton Rouge's water are around 1600'. I seem to remember that from a project in college. I'm not familiar with large scale land fracking, but in offshore sandstone reserves, the frack takes place when the frack fluids penetrate the porous formation and then the viscosity allows the fluid to build pressure and break the rock. There are non-permeable geological layers above pay zones. They are the reason the oil is trapped there. If the frack fluids can't penetrate the rock, it cant break it. I wouldn't want to frack 10' from a water source, but there are literally dozens of layers of geological formations that could be separating the water source from the pay zone
