Sewers were one of the earliest and most impactful advents of public health in urban areas, and it’s exciting that we’re still finding new ways to use them to that end.

"Literal stream of data" Took such a nice approach to that. I'd have gone with something like "Crapload of data"

"Brown mirror" made me simultaneously laugh and grimace at the same time! Nice work Grady.

I've never been so interested in sewage since watching this channel

We've been using wastewater monitoring to track illicit drug use here in Australia, for some time now. I will say that its not the best feeling though to hear that your state has the highest use of methamphetamine in the country, based on sewage sample data!

Apparently one of the common ways of normalizing sewage concentrations against population (and dilution) is to measure the concentration of an extremely durable pepper virus, pepper mild mottle virus (PMMoV). People eat enough chili and sweet peppers that this can be used as a very rough baseline indicator of how much fecal matter originally entered the waste stream.

The hardest part about 15 days to flatten the curve is the first 18 months

T-Shirt design: NWSS logo on the front. Data Contributor on the back. I'd buy it.

I can already see the DEA pulling warrants for people's septic tanks.

I know they set up hundreds of lift station samplers throughout my county, they were very careful to keep the data from being too refined. a neighborhood, yes, a building no. one of my clients was in upper management for the program run at the state level. as he is a privacy advocate, he made sure to keep things from being too specific. very cool system.

As a nurse, it's not every day I get to see my two favorite subjects (medicine and engineering) merge into one video! Nice job Grady!

In Sydney Australia sewage monitoring was an early part of the covid dashboard. It often highlighted outbreaks in suburbs days before any actual positives were reported. The sewage analysis was an important tool in directing health authorities to where they needed to promote testing campaigns and notifications.

So there’s laboratory testing and… lavatory testing?
28 |
"Maybe it would be called Brown Mirror" Well Done Sir

There were some drug busts in a coastal town near the town I lived in where the flow of waste water from the houses under surveillance was "filtered" with what was essentially a pool net. The Sheriff's department would announce their search warrant as a chainsaw was used to cut through the waste water pipe leading to the septic tank, the net held at the break waiting on the drugs to be flushed.

"Brown Mirror"... That must have taken a couple takes to say without giggling!
Excellent content as usual, Grady!

I'm glad he dipped into the ethics, this was the first thing I thought of, because that's inevitably how operations work out in the States; either the government and/or some big corpos look to get their hands on it

In addition to the random saliva testing of students and staff, the University in our city was regularly sampling the waste water around their dorms to try to gauge infection rates. It was much higher than previously assumed by city's municipal officials. However, the school is also notorious for partying - even during the pandemic, which certainly did not help to contain the spread. Appreciate that you went in on the ethics of sampling waste water.

This is an absolute testament to human ingenuity. I love these sewage videos. Thank you Grady.

In an attempt to further ensure my on- and offline privacy I am hereby committing to only shitting into a hole I dug in the garden.
