And it's all cool until something breaks. Which it does btw. I spent about 60 hours straight analyzing the stuff coming up out of parking garage floors, fire hydrant openings, street manhole coverings etc. That was a big OOOPs on the part of the oil company.

They have these geological structures where they pump natural gas into them under pressure to store locally until they need to draw it out during high demand. Until they pressurize it too much and it breaks, which has also happened here in CA.

Nick,

again, I say, just as a new yorker being familiar with our DEC, it's pretty thoroughly corrupt. If they're trying to cut ahead of the conclusion of the EPA study, you need no science to conclude that it is an action in favor of the gas companies.

Well, yes, we DID figure out where it came from. It came from an oil company that had over-pressurized the field and broke the rock, the pipes, and the well-casing - and the pressurized oil and extraction fluids, moving up to areas of lower pressure, came out wherever they encountered a surface penetration - alongside pipes and foundations - in downtown LA.

Did you not understand that? I thought it was abundantly clear. Do you need me to use smaller words? Or simpler concepts?

That's a completely pointless bit. What does that have to do with companies accidentally breaking geological structures by over-pressurizing them? Unless you mean to say that they ALSO accidentally break geological structures with water. In which case - THANKS! - for making my point for me!

I don't see the fluids pumped into the ground as an issue with the ground water.

If you mean dumping fracking fluid on roads as brine, that's how leaching HAPPENS. Leaching to groundwater. You put enough on the soil, some will sorb on the soil particles but the stuff is heavier than air, gravity pulls the rest down through the pore space until it hits the saturated zone.

If the stuff is an LNAPL, lighter than water, it'll spread out on the surface. If it's a DNAPL, it'll sink in the system until it hits an impermeable layer and either pools or passes through, or you have flow in a strata that mobilizes, or it disperses into solution, or all of the above.

If you're pumping it in deep, you're pumping it in to the groundwater system. When you fracture a strata, you release fluid into overlying layers, and potentially to strata subject to the recharge/discharge flow pattern. And even when you're in impermeable layers, transmissivity is not zero. This stuff WILL eventually migrate as dictated by groundwater flow.

No matter what, dumping or pumping these fluids is an issue with groundwater. The question YOU'RE meaning to ask is if it is an issue with drinking water. But that's not the only issue here, many of the impacted areas have a shallow water table, and so vapour intrusion is a concern.

I was talking about pumping it into the ground. The thing is that you can pump deep enough that you are not affecting the ground water. Useable ground water is only found so far down.
