Hi, these are the weekly #washingtonstate #kingcounty (that is, #seattle and environs) #COVID #COVID19 #wastewater toots.

A quick reminder that this King County respiratory disease data comes from Washington State, not the federal government.

The West Point (WSPT) sewage treatment plant's 7-Day running average is the lowest[*] it's been since the state switched data providers in fall of 2024. And you know what that means: it's time to deploy some celebratory emoticons: πŸ˜πŸ‘―πŸŽ‰The last data was calculated on 11/9.

[*] if you exclude the 0.0 "no data" placeholder values that pop up from time to time in this dataset.

WSPT is one of three King County(-ish) sewersheds in this dataset. You can find overviews, individual sewershed results, and a breakdown of variants for the state wastewater surveillance program, along with other metrics like case counts and hospitalizations for Covid-19 and other respiratory illnesses, at https://doh.wa.gov/data-and-statistical-reports/diseases-and-chronic-conditions/communicable-disease-surveillance-data/respiratory-illness-data-dashboard#WasteWater. If you go to the page and click "learn more" in the statewide view tab, you can find out lots of details about how these data are calculated and how to interpret them. The dashboard gets updated every Wednesday (generally). The Department of Health is here on the fediweb, at @WADeptHealth

Edit to fix up an emoticon fail.

The Brightwater sewage treatment plant (BWT) in Woodinville is also nice and low. The last 7DRA calculation was made on 11/12.
The last of the three King County sites is King County South (KCS) treatment plant, and its Sars-CoV-2 7DRA numbers are also nice and low. The last 7DRA calculation was made on 11/12.
