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

And that's just one of hundreds and thousands...maybe more, eh?

This city should not exist. It’s a monument to man’s arrogance.

Neat. I can’t remember, a re you in an environmental program or a geospatial program?

Sadly, I’ve stumbled across that site already. What a shitshow!

It’s good that you’re learning GIS. It’s incredibly useful in this field. I’ve done plume (underground and smoke) analyses, alternatives impact analyses, habitat estimation, flood impacts, endangered species, and more. I tend to think geospatially, so my first question in any project is “where?”

There are 40,000 known sites with 1,600 being listed as a priority. There’s obviously a whole bunch we don’t know about. I can’t count ho w many times I’ve stumbled across DIY dumps in the desert. Who knows what people have disposed of out there, especially with the rise of meth over the last few decades. Here’s a map of our National Priority List
Pretty ironic when you think about how advanced we view ourselves. In Motorola’s case being able to manufacture microchips, then thinking it would be ok to just dump solvents in a well.

Unfortunately, yes. Hopefully one that actually pays.

Do you study the PFA contaminated too?

I see lots of frothy water like that i n little creeks in the woods. I don't know if there's another explanation for it or if it's from contamination.

It’s so fun finding out what companies used to dump back in the day! A local lake was the dumping ground for a lot of transformers, so now it is highly contaminated with mercury. Then there is the whole Savannah River Project issue nearby.

Not specifically, but PFAs are now classified as hazardous waste, so I’m learning about their detection and cleanup in general.
You’re in New Jersey, right? While there are lots of NPL sites there, there’s also lots of people and lots of money, so ignoring contamination is less likely (now). I wouldn’t worry too much about froth in streams. L ots of dissolved oxygen, nutrients and, therefore, organisms. You can always take a sample to your nearest water lab. Use a water bottle, rinse it in the stream a few times, and keep it chilled and out if sunlight during transport.

Thanks for sending me down the TCE rabbit hole. I read they have removed 57,000 lbs of the stuff from that aquifer already. I guess it’s a good thing it’s not soluble?
I’ve sold carbon adsorption vessels for soil remediation projects on sites such as old dry cleaners but nothing on a superfund scale.
Makes me think about all those hours cleaning parts in the parts washer or cleaning my hands with brake kleen
