Interestingly, the downloadable data is population-normalized in a way that you don't see on the facility trends page. Its sample units are reported as \"Normalized Pathogen Concentration (gene copies/person/day).\"</p><p>At present there are three King County area treatment plants represented: Brightwater, covering both King and Snohomish Counties; West Point, in King County; and King County South, covering both King and Pierce Counties.</p><p>For a while many sites weren't getting updated, and presumably this was fallout from the Biobot/Verily transition (see below). But as of 10/27/2023, nearly every site is being updated, with some of the data being provided by the state Public Health Lab. (There used to be a popup attached noting that the PHL methodology is different from the previous Biobot methodology, and that therefore the historical Biobot data has been removed. I haven't seen that popup in a while, though.)</p><p>The dashboard as a whole gets updated every Wednesday. But you'll need to look at the dates in the underlying facility trends table to see how recent the site-level data are. Sometimes the downloadable data trails the graphically-presented data, so I check recency by right-clicking the specific facility view and selecting \"show as table,\" and scrolling down to look at the last entry for the timestamp.</p><p>King County's Respiratory virus data dashboard page</p><p>King County also reports wastewater data for the three facilities listed in the State's dashboard, also based on the State's Public Health Lab data.

The latest sample date is given on the lower left-hand corner. It's a pretty basic chart -- for example, there's no download option -- but if the State's wastewater dashboard didn't get updated in a given week, you can often find the most-recent PHL data here.</p><p>CDC's OG Covid-19 Data Tracker Wastewater Surveillance page</p><p>The CDC's National Wastewater Surveillance System (NWSS) has two different web pages for wastewater metrics and visualization. I'll start with the original page, which covers national and regional trends. You can also look at state, county and sample site metrics for current virus levels, percent change in the last 15 days, and percent of samples with detectable virus.</p><p>This OG CDC page is here:<br><a href=\"https://covid.cdc.gov/covid-data-tracker/#wastewater-surveillance\" target=\"_blank\" rel=\"nofollow noopener\" translate=\"no\"><span class=\"invisible\">https://</span><span class=\"ellipsis\">covid.cdc.gov/covid-data-track</span><span class=\"invisible\">er/#wastewater-surveillance</span></a></p><p>There is also an option to download the entire data set, or data for a specific site.

In a nutshell: Biobot was the original data provider for a subset of the sites; in mid-September 2023 when the contract concluded the CDC awarded the new contract to Verily instead; Biobot filed a complaint about the contract, with the Verily contract on hold until the complaint is resolved some time in 2024; the CDC NWSS site lost over 400 sites out of its dataset as a result; and in mid-November the CDC created a short-term contract and awarded it to Verily to get those sites back online. As the contract dispute has evolved, there have been a few press articles. Salon has an article about the switchover and its impacts here: <a href=\"https://www.salon.com/2023/10/19/a-lapse-in-wastewater-detection-is-worrying-scientists-about-distorted-data/\" target=\"_blank\" rel=\"nofollow noopener\" translate=\"no\"><span class=\"invisible\">https://www.</span><span class=\"ellipsis\">salon.com/2023/10/19/a-lapse-i</span><span class=\"invisible\">n-wastewater-detection-is-worrying-scientists-about-distorted-data/</span></a> Politico has an article here: <a href=\"https://www.politico.com/news/2023/10/26/detecting-covid-surges-contract-dispute-00123787\" target=\"_blank\" rel=\"nofollow noopener\" translate=\"no\"><span class=\"invisible\">https://www.</span><span class=\"ellipsis\">politico.com/news/2023/10/26/d</span><span class=\"invisible\">etecting-covid-surges-contract-dispute-00123787</span></a>.

The nice thing is they figured out a way to harmonize the sample data across different providers. So you can see how today's reported state-level numbers look compared to, say, January 2023, before the big Biobot -> Verily switchover. There's no county-level data, but I've read that such a feature is on their roadmap.</p><p>There's an explanation about how they calculated the viral activity levels here: <a href=\"https://www.cdc.gov/nwss/about-data.html\" target=\"_blank\" rel=\"nofollow noopener\" translate=\"no\"><span class=\"invisible\">https://www.</span><span class=\"\">cdc.gov/nwss/about-data.html</span><span class=\"invisible\"></span></a>.

Their wastewater testing dashboard is here:<br><a href=\"https://publichealth.verily.com/?v=SC2_N&l=Coeur+d%27Alene%2C+ID\" target=\"_blank\" rel=\"nofollow noopener\" translate=\"no\"><span class=\"invisible\">https://</span><span class=\"ellipsis\">publichealth.verily.com/?v=SC2</span><span class=\"invisible\">_N&l=Coeur+d%27Alene%2C+ID</span></a></p><p>As of this writing, there's one Washington State site, the City of Snohomish, listed. It is up to date.</p><p>Verily has a good description of their methodology here: <a href=\"https://publichealth.verily.com/about\" target=\"_blank\" rel=\"nofollow noopener\" translate=\"no\"><span class=\"invisible\">https://</span><span class=\"\">publichealth.verily.com/about</span><span class=\"invisible\"></span></a>.</p><p>Verily's COVID wastewater data is part of their multi-disease wastewater dataset, hosted at WastewaterSCAN.org. This site has data at the national, regional, and sample-site level. You can download this data from: <a href=\"https://purl.stanford.edu/mz061vb5322\" target=\"_blank\" rel=\"nofollow noopener\" translate=\"no\"><span class=\"invisible\">https://</span><span class=\"\">purl.stanford.edu/mz061vb5322</span><span class=\"invisible\"></span></a>.</p><p>Biobot</p><p>Biobot was the CDC's previous wastewater data supplier and was for a while continuing to publish wastewater data in a dashboard at <a href=\"https://biobot.io/data/\" target=\"_blank\" rel=\"nofollow noopener\" translate=\"no\"><span class=\"invisible\">https://</span><span class=\"\">biobot.io/data/</span><span class=\"invisible\"></span></a>. But as of May 14th, 2024, they've sunsetted their dashboard.
