I'm Nervous About Nylon!

I'm again ravin' about Maven! I find more interesting articles on that webpage (I subscribe to the daily digest), although a few days ago it was a bit more scary than usual. The topic was microplastics, and slightly off topic of what my topic today is, nylon, apparently just what micro-plastics are has not yet been precisely defined by the State Water Board in terms of size! Off topic I know, but the PhD brainiacs are tasked with coming up with a legal definition for regulations by 2021.

Microplastics are in the oceans, in fish, in everywhere basically, as plastic breaks down into smaller and smaller particles with age. (Hence the need for a precise definition; what size are they anyway?) For example, I was weeding in my back yard on Friday, as the stay-at-home orders have caused a remarkable amount of free time to now spend on other things which heretofore was unavailable due to in-person meetings as opposed to the current Zoom meetings. No time wasted on driving to get there or spending depressing amounts of time squishing myself into my increasingly shrinking jeans! COVID-19 is causing a weight crisis in my life. Anyway, I found an old plastic bag amongst the weeds, and I literally could not pick it up; it kept breaking into smaller and smaller bits!

Now for the equally and more personally scary part, as I have had no time to get used to this idea the way I have with micro plastics. Apparently, polyester, nylon and synthetic fibers shed when you wash clothes made of them and this material winds up at wastewater plants. Now in the video linked below, the interviewee says this does not get filtered out and winds up in discharge waters from the plant. Well, at the moment, we have no discharge waters, our recycled water goes to the Broderson leach field, the golf course, maintaining wetlands at some point, non-existent farmers at the moment, school playgrounds. Up to 40% of the artificial garment material goes down the drain to wind up swirling around in our primary clarifiers!

Well, take a look - go to 17:21 on the video for this ghastly revelation:


Am I clogging up the Broderson with my molting nylon leggings? I have seven pairs! This is depressing. I am feeling guilty. Cotton just does not stretch, which is an especially needed feature right now.

WEF's Wastewater Professional Guide

Readers here, all three of you, but maybe you are actually bots not readers (Russia still likes Los Osos according to the analytics provided by Blogger), well, whatever you are, you are getting more reading material (or maybe just cataloging data) of late from me! Small comfort I know during this horrid time. 

But, I have the time now to write! Zoom meetings do not require driving someplace or even wearing anything but jammie bottoms as long as you have a nice, business-like top on, some jewelry and make-up, not to mention root concealer, argh, I miss my hairdresser horribly! Hey, bunny slippers instead of boots, although mine actually have cats on them.

So I get this great notification from Maven's Notebook daily, and some sewer emails as well (it is amazing what one can subscribe to) and I found more info on COVID-19 and sewers!

So here you go - do follow inks off of this page too:
http://cweawaternews.org/water-wastewater-professionals-guide-to-covid-19/
"Research is ongoing, but experts currently believe that exposure to wastewater is not a significant transmission route for COVID-19 virus."
On another note, I was cleaning some random papers off my desk and found a note to myself on creating a sewer dance. Why not? I am not much of a dancer, but COVID boredom might get something going.

(Hey, a pixelated wave from me to you Russia! 😜)
