ExxonMobil sits at the epicenter of one of the top 3 purest water tables in the nation, squat on the Mississippi River in Baton Rouge. [0]
The insane amount of water they use for oil refinement is causing the entire surrounding area to leech hard water. What was once the softest table in the region is now becoming infested with salt water.
I have seen the water table schematics, I used to live a couple of miles from the plant and I can tell you that even in the last decade it's gotten noticeably worse.
This is objectively worse than the alternative, using hemp for biodiesel and bioplastics which requires far less water and doesn't ruin the environment.
