First, let me take you exactly to where to find these results:
• for now, it is the only graph on the "Wastewater" tab
• hosted at @ucalgaryCHI, the results are province-wide including years of innovative work by @UAlberta, @UCalgary, @ACWAWater et al
Now, although the CMOH said on 7 Dec 2021 it was just about here, after that I could find no information from CMOH, AB Health, or GoA about where to find the website, or how to use it.
It is as if the Gov had been suppressing this information for so long, it sorta squeezed out.
In May when I built my #BalancedScorecard, I included @ucalgaryCHI wastewater sampling:
• it remains independent of government reporting
• not completely reliant on GoA funding
• everyone poops; not everyone gets swabbed
• wastewater sampling was a few days ahead of PCR
During Aug long weekend, I focussed on independent, daily R from @imgrund + wastewater sampling from @ucalgaryCHI, because:
• GoA's 28 July 2021 decimation of Test/Trace/Isolate would understate cases
• GoA was suppressing Alberta-wide results eg. UofA
In September, when we finally saw disinformation to cabinet in June to launch 4th wave:
• more empty promises about making wastewater results available
• which took until Dec to shart publicly
• did we ever see any local response, rather than top-down?
With above screenshot, I may have subtweeted @jvipondmd@PopAlberta@GosiaGasperoPhD with CMOH's notorious "SHIFTING FROM PANDEMIC TO ENDEMIC" document that:
• over-relied on highly-vaxed UK to predict AB Hospital
• cherry-picked worst to become worst
But I digress. Now that we have Alberta-wide wastewater sampling results:
• in a vacuum of information from PCR testing suppressed
• and rapid-testing results unavailable
• let's use it while we got it.
1. Click on the name of your town or city on the map of Alberta on the right.
This will give you the graph for eg. Edmonton, which has been in just as much trouble as Calgary, and for which there are results since June 2020.
Why didn't we see that before, you may ask? Me too.
2. "Comparing sites is also problematic because different communities have different proportions of residential and industrial water use contributing to their municipal wastewater. The most important signals to compare are within a given community by following trends over time."
That's what most of us are looking for anyway:
• how is my town or city doing?
• how is the town or city of my loved ones, or my workplace, doing?
• oh ya, I remember we had it pretty bad around here before - you can see that confirmed in the wastewater sampling too, eh
"What the heck is this?" you may ask.
• Starting Date - eg. you can look since 1 July, for launch of the 4th Wave, or from 25 Nov, for neglect of the Omicron Wave
• Raw v Normalized - See Dr Parker explanation ⤵️
• I'll try to be your PhD whisperer
3. Raw v Normalized?
Raw = count of virus independent of whether lots of rainwater got into sewer, or industrial/residential mix
Normalized = uses fecal microbiota marker like Pepper Mild Mottle Virus* to focus on human poop in the wastewater.
* resists making jalapeño joke
4. N1, N2 or Average?
N1, N2, etc. are target sites on the virus that the wastewater sampling lab looks for.
If you want to know way more than me on this, read:
True picture (therefore control) of #COVID19AB has been suppressed by 28 July 2021 Public Health Order that decimated Test/Trace/Isolate during 4th Wave.
Therefore we have to look at other signals like Wastewater Sampling, independent Daily R, and help from @bcCOVID19group...
@bcCOVID19group Dr Karlen had to switch from Cases to Hospital Admissions, and then analyze the lower testing volumes and higher test %, to explain Alberta's Urban/Rural Delta Wave.
Let's look at each one individually. Here:
• Virus measures N1 & N2 compared to new PCR swab test cases, and to test positivity
• As Dr Parkins explains (not Parker as I misstated above), wastewater virus sampling predicts both PCR swab test cases & positivity by about 6 days
Here, we see just how good the correlation between wastewater sampling results, and the 5-day moving average of daily new cases from swab tests.
Just as Dr Karlen at UVic infers underreported Cases from Hospital Admissions, we'll be able to infer them from Wastewater Sampling.
We see that here:
• Waves 2 & 3, qty of actual cases predicted 6 days earlier from wastewater sampling model was close.
• actual cases dropped off as swab testing capacity saturated ~ 20K tests/day
• in Wave 4, actual cases were below model, similar to what Dr Karlen saw.
Since we're here, let's look at Dr Karlen's 29 Dec model.
What's even scarier, is that Dr Karlen modelled these outcomes on 29 Dec, before AB Health had updated Hospital Admissions since 22 Dec (3.5/day/million people).
His next update will have the latest (currently 9.1).
2.6x higher, and climbing Omicron-fast.
I wish there were a simple formula like:
Cases = a x Wastewater + b
But we have to work more from trends than data points.
Dr Karlen has explained that pandemics have trends with the same slope for a while, than a switch to a new one. @GosiaGasperoPhD shows this too.
@GosiaGasperoPhD In the fall, I attempted to correlate @imgrund R with @ucalgaryCHI Wastewater project, who are inferring Cases from wastewater.
A different approach than @bcCOVID19group use of Hospital Admissions.
I know I lost some of you moving from wastewater into his modelling, but may have picked up some ID docs, epidemiologists, engineers, etc along the way who are able to see the connections better than me.

I was going to tweet about my early dinner tonight at Palomino (cliché food pics) but just got hit with wall of SWEET sound when I went downstairs to use the washroom, and opened the steel door to basement concert hall.
WOW.
This is "Olde Ghosts" warming up - in this program.
I am a nerdy 58-yr-old engineer who surprises people with 2 unexpected traits: a love for good metal, and endless jokes.
On the latter, I am like Leslie Nielsen who could easily get even people braced for his hidden fart accordion to crack up. But I'm not using one....yet.👺
With metal, I was raised with Indian music my parents played, like the Pakeezah soundtrack, until the cassette literally broke.
This is one of the songs from that movie. It builds until Meena Kumari (Indian's Marilyn) dances with those 2 😍 backups.
I’ve been eating a lot of rich, flavourful food recently, and I went from a salmon/capers omelet at OEB to the passcode protected washroom in food court at Fifth Avenue Place. Took a massive, relaxed dump.
Laughing as I type.
So I’m washing my hands - even had the foresight to take a restaurant napkin to dry my hands and use on the door lever to exit (trust me on this) and a distinguished gentlemen t about 60 walks in.
And visibly buckles, and groans.
I’m trying not to laugh out loud.
I step out of washroom and all of this is hitting me as I walk slowly to exit escalator, down to a bench on 5 Ave, where I am typing this now.
I’m almost crying not to burst out laughing.
And the Punjabi woman security guard sweetly asks me “Are you OK?”
🧵 Alberta's Reigning Queen of deceptive cherry-picked public health stats, Health Min LaGrange, was back at it Monday, this time over measles immunization.
Bonus Topic: Where is the source for the widespread claim that airborne measles is only infectious up to two (2) hours?
@TheBreakdownAB @JMeddings @PfParks @LukaszukAB @JenLeeCBC @GosiaGasperoPhD @Mark_Ungrin @dupuisj @DrFiliatrault @TimmCTV Let me provide the links for the above two graphics:
@TheBreakdownAB @JMeddings @PfParks @LukaszukAB @JenLeeCBC @GosiaGasperoPhD @Mark_Ungrin @dupuisj @DrFiliatrault @TimmCTV On the deceptive, cherry-picked measles immunization stats, LaGrange said "Since March 16, there has been a 67% increase in comparison to last year."
The VP who oversees the restaurant was not on, but I left my business card.
My @Hyatt loyalty card, which shows zero as it has not updated for my purchases since February, when my car died, and I found walking there convenient. High prices, but matching food & service (!)
@Hyatt Now, I don’t care about my points, as I will never visit @HyattCalgary again, for any reason.
I won’t spend much time with the VP if he or she calls me. This is their problem to solve, not mine. I’ll get nothing from it either way - I’m gone.
Dear @CalgaryPolice and other smart people. I'm looking for 2 things:
• video of press conference and written response by Chief @neufeld_mark to Dreeshen's stupid announcement early Dec 2024
• GoA policy & evidence to get sites approved for photo radar
@CalgaryPolice @neufeld_mark I didn't know until now of this formal 12-month pilot while looking for more information related to my witnessing a cop nearly killed on Centre Street @ Samis Road on Sat night by a speeder who pulled over, then zoomed away.
@CalgaryPolice @neufeld_mark @reportrix @MBellefontaine I always knew Dreeshen's announcement, served in a "No Cash Cow" BBQ apron with Beef on a Bun for reporters, was colossally stupid.
I learned it kicked in on 1 April.
Will talk on record about my direct personal experience from this Saturday night.
