Ten hours later and I’m finished with my Soils and Groundwater Contamination midterm. Some CERCLA porn for your time.

Illustration for article titled Well that was fun.

For those that don’t know what this is, it’s the estimate of a groundwater contamination plume that stretches from eastern Phoenix into downtown Phoenix. ADEQ is now saying it stretches all the way to Tolleson. In the 1950's, Motorola was making microchips here. They dumped about 116,000 gallons of trichloroethylene (TCE) into a dried out well behind the plant. It percolated down into the groundwater, and spread west and north. TCE is denser than water, so it sinks to the bottom of aquifers and is nearly impossible to remove. Estimates are in the 1,000s of years for cleanup of this plume, meaning it’ll never happen. Have a good night, Oppo!
