The DMN tells me things I did not know about my current favorite public works project.
The [Houston] health department is conducting the wastewater surveillance for COVID-19 in partnership with researchers at Rice University and Baylor College of Medicine. Wastewater testing cannot identify individual people who have COVID-19, but it can identify neighborhoods with particular virus variants or relatively high virus loads.
Dallas County is not participating in similar wastewater surveillance to track the virus, said Dr. Philip Huang, director of Dallas County Health and Human Services. He said he doesn’t know of any other organizations or municipalities in North Texas that are operating similar programs.
While Dallas County previously considered using wastewater surveillance, the price of creating such a system was too high. “It’s actually quite expensive to set that up,” Huang said.
“After the 10-week survey, [the water district] discontinued its participation in the study due to inconsistent data that required continuous interpretation by local and state public health officials,” said Kathleen Vaught, public relations specialist at the water district.
Public health experts have long used wastewater samples to track the growth and spread of bacteria and viruses, like the poliovirus.
The Centers for Disease Control and Prevention began discussing the use of the tool to study COVID-19 in February 2020.
By September of that same year, the CDC and the U.S. Department of Health and Human Services launched the National Wastewater Surveillance System, also known as NWSS, to help state, tribal and local health departments track and respond to COVID-19.

Houston is the only Texas city to participate in the NWSS, although that could change as the program grows in the next month, said NWSS team lead and CDC microbiologist Dr. Amy Kirby. Data taken from Houston wastewater samples is submitted to a national database tracking similar data from nearly 400 utilities across the country.
The University of California, Merced’s Naughton Lab created and maintains a dashboard, called COVIDPoops19, to track global wastewater testing for the virus.
I just want to say that learning of the existence of a dashboard called COVIDPoops19 has improved my life in ways I could not have imagined. You can zoom in on Houston in this dashboard and click on the various icons to learn more; clicking on the icon for Baylor College of Medicine led me to the actual Houston dashboard for this, which I had not seen before. If you play around with the slider, which shows you what the viral levels were for past weeks, you can see that the inflection point for this year was the week of June 21 – levels had been dropping through June 7, then you saw a few upticks on June 14, and on the 21st it was all increases, and it got worse for the next few weeks. We’re on more of an upward trend right now (December 6 is the most recent date), but there are increases and decreases in the various locations. I’m going to be bookmarking this page. Anyway, if you want to know more about this project, there you go.
