#NYC #COVID #wastewater counts are still available on the New York State run portal, but not in the State open data repository.
In the State portal, #COVIDWastewater data is only available as one of two embedded Tableau charts - a graph or a map. The embed code is available, but it is a permalink to a snapshot of the data in time; it does not always show the most current data.

The #NYC Department of Health and Mental Hygiene released its July #COVIDWastewater data on August 3. It's now September 14, and there's no sign of the August data.
#Wastewater concentration is one of the most important indicators in the beginning of a #COVID wave.
The samples are tested within a few days of being collected. Something the Department of Environmental Protection or the DOHMH is doing between testing and the public repository is taking way too long.

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.
Last week I highlighted really terrible SARS-CoV2 concentration numbers from the West Point (WSPT) sewage treatment plant's 7 day running average for 8/25, but said, maybe this is a crazy outlier, let's see next week's numbers. Well, they're in, and the updated numbers are quite, quite bad. These calculations of the 7DRA were done on 8/30 and 9/1, and they are by far the worst numbers we've seen in a year (which is as far back as the dataset goes). :( :( :(
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.

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, well, sucky. The last 7DRA calculation was on 8/25. The only thing I can say about this is that this running average was just bouncing around, but then completely busted out in the two days from 8/23 to 8/25. It will be good to get some more data points next week to tell us if this is some super crazy outlier or not.
Also, you might notice the banner above the graph that says: "The CDC updated how it measures wastewater viral activity level (WVAL) in August 2026. Our dashboard currently uses the previous method while we work to incorporate these new updates." WVALs are the CDC categories used to describe very high/high/moderate/low/very low virus detection levels, and they get a fair amount of criticism because the category recalculations result in changing baselines that obscure year-over-year trends. I believe these WVAL categories get used in the state's "Statewide view" tab, so the CDC changes will affect that. By contrast, the facility-level graphs that I post each week are linearly-scaled graphs of seven day running averages of detected concentration levels. Whatever happens with the WVAL category definitions, it won't affect this facility-level reporting.

"Testing underway on new solar wastewater system to tackle Hawaii’s cesspool crisis" https://www.hawaiinewsnow.com/2026/08/27/testing-underway-new-solar-wastewater-system-tackle-hawaiis-cesspool-crisis/
unfortunately the article provides no details about the system itself. is it aerobic? anaerobic? what does it do?
the official that they showed in the video gave no information aside from "there's lots of data", "it's top of the line", and "it's solar-powered".
also, it says that it can handle 600 gallons per day. for reference, the department of health assumes that a building produces 200 gallons per day per bedroom. so 600 gallons per day is a 3 bedroom house.
unrelatedly, i saw something in the video about it being a "meander tank", so i started searching around, and ended up on a website for "kauai wastewater solutions", which inspires 0 confidence with its AI graphics. what are those boys in the top picture even putting in the ground????? https://kauaiwastewatersolutions.com/blog/septic-system-installation-kauai-your-ultimate-guide/ 🤦

Greetings, 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 climbed up some more from last week's numbers. The last 7DRA calculation was on 8/18. PS, it looks like the data for the ~ six week outage early this summer got backfilled for all three sites.

#GallupNM #datacenter water deal draws #Navajo concerns
By Donovan Quintero | May 14, 2026
"A proposed data center on Gallup’s eastern industrial edge has raised questions about water, jobs, public notice and whether the project could affect the Navajo-Gallup Water Supply Project.
"The Gallup City Council is considering whether to extend a long-term reclaimed water option tied to #TeraplexDataCentersLLC, a Virginia limited liability company identified in city documents as seeking to develop industrial and commercial uses, including a data center, on roughly 330 acres in Gallup.
"Public materials describe Teraplex as a modular data center and power infrastructure company focused on #AI computing, integrated power systems and factory-built infrastructure. Publicly available company materials do not clearly identify completed or operating data center campuses owned by Teraplex."

Gallup data center proposal raises water, jobs and notice concerns
Marcus Williams, 5/17/2026
"A 330-acre #GallupTradeport data center could send nearly 110 million gallons of #wastewater a year into a water-stressed region already waiting on #NavajoGallup deliveries.
"Gallup City Council put off action April 29 on a wastewater deal tied to a proposed 330-acre data center in the Gallup Tradeport, and the scale alone sharpened the stakes: nearly 110 million gallons of wastewater a year could be routed to the project if the agreement advances.
"That number is now colliding with a much larger question in McKinley County and across the Eastern Navajo Nation, who bears the risk if a private technology campus moves ahead in a region where water is already scarce. At a May 14 discussion, speakers raised concerns about water use, public notice and whether the project could affect the Navajo-Gallup Water Supply Project, the long-delayed system meant to carry municipal and industrial water from the #SanJuanRiver to Gallup, the eastern #NavajoNation and the southwestern #JicarillaApache Nation."

High tide for #Holtec
#Tritium dumped into #CapeCodBay will wash back onto community shores, says a new report
"The permanently closed Pilgrim nuclear power plant is now owned by Holtec, which wants to dump #RadioactiveWastewater into Cape Cod Bay. While waiting for a permit, so far denied, the company is quietly venting #tritium into the air."
by Linda Pentz Gunter, Posted on December 29, 2024
"Holtec, the company that has purchased a number of permanently closed #nuclear reactors in order to decommission them, has encountered yet another obstacle to its '#dilution is the solution to pollution' plans.
"One of the reactor sites Holtec has taken over is #PilgrimNuclearPlant in Plymouth, Massachusetts, on the Cape Cod Bay, which closed permanently in 2019. Holtec’s not-so-little problem there is what do with what started out as at least 1.1 million gallons of radioactively contaminated #wastewater stored at the site.
"The company first suggested it would simply release the wastewater into Cape Cod Bay, assuring residents and the immediately alarmed fishing community not to worry because (a) the wastewater isn’t dangerous anyway (b) everyone does this all the time at reactor sites and no one has gotten sick so far and (c) it would quickly disperse into the wider ocean. Holtec chose this disposal method for one reason alone: it is the cheapest.
"The proposal was vigorously fought by citizens, the state, and powerful Massachusetts Democrat, Senator Ed Markey. The state of Massachusetts effectively banned the discharge option, a decision Holtec is contesting.
"That Final Determination to Deny Application to Modify a Massachusetts Permit to Discharge Pollutants to Surface Waters was issued by the Massachusetts Department of Environmental Protection [#MassDEP] Division of Watershed Management on July 18, 2024. A month later, Holtec launched its appeal to reverse the decision, something that could take months or longer to find its way to court.
"In the meantime, help has come from a new quarter in the form of an in-depth study by the prestigious Woods Hole Oceanographic Institution [#WHOI], also, as it happens, based on the Massachusetts shoreline, near Falmouth.
"The study — Model-Based Study of Near-Surface Transport in and around Cape Cod Bay, Its Seasonal Variability, and Response to Wind — found that contrary to Holtec’s claims, the wastewater would not immediately disperse into the ocean, but would linger potentially for months, and wash up on the shores of area communities.
“'We found virtually no out-of-the-Bay transport in winter and fall and slightly larger, but still low, probability of some of the plume exiting the Bay in spring and summer,' said Woods Hole study leader and physical oceanographer, Irina Rypina.
"The radioactively contaminated wastewater stored at Pilgrim is contaminated with what Holtec and the Massachusetts Department of Public Health have described as 'four gamma emitters — #Manganese54, #Cobalt60, #Zinc65 and #Cesium137 along with #Tritium, a beta radiation emitter'.
"While the Woods Hole Study did not look at the health outcomes of releasing the radioactive water into Cape Cod Bay — only at the plume pathway — there are plenty of data that demonstrate the harmful effects of these #radioisotopes on human health, especially women and children.
"After acquiring the Pilgrim reactor, Holtec’s President and CEO, Kris Singh, assured surrounding communities that,
'the decommissioning of Pilgrim will replicate the superb record of public health and safety and environmental protection that typified the plant’s 47 years of operations.'But since that acquisition, Markey observed, 'Holtec has fallen woefully short on this commitment.' He noted of the Woods Hole report that 'In light of these recent findings, I urge Holtec to develop a wastewater discharge plan that is informed and guided by scientific fact and community input.'
"Long-time #PilgrimWatch activist, #MaryLampert, welcomed the report’s initial findings and said that 'Holtec dumping Pilgrim’s radiological and chemically #contaminated wastewater into semi-enclosed CapeCod Bay is harmful to human health, the environment, and our marine economy.'
"In a handbook explaining Pilgrim’s decommissioning process on the Pilgrim Watch website, the authors note that 'Cape Cod Bay, #PlymouthBay, #DuxburyBay, and #KingstonBay are all protected #OceanSanctuaries. Cape Cod Bay is a critical habitat for right whales and other endangered or special species. Dumping this #radioactive and chemically contaminated wastewater into them would cause incalculable economic damage and would harm both the environment and public health.'
"Absent a liquid discharge permit, Holtec’s preferred solution since has been to quietly evaporate the wastewater into the air. It has done this, as revealed during a Pilgrim Nuclear Decommissioning Citizen Advisory Panel meeting, by installing submerged electric heaters to increase the plant’s ambient temperature, ostensibly in order to improve worker comfort and expedite the drying of plant components.
"But, as Markey noted in an April 30, 2024 letter to Singh, the consequence of installing the heaters in that location 'is an increased rate of wastewater evaporation above the pace at which it occurs naturally.' That 1.1 million gallons is now down to 880,000 gallons remain, according to Holtec’s own reports.
"As Lampert points out, 'Meteorology studies show 60% of winds blow offshore,' which means at least some of that evaporated wastewater is going to fall into the bay anyway.
"Under Nuclear Regulatory Commission rules, Holtec has four disposal options: liquid discharge, evaporation, storage onsite, and shipping to a licensed facility. None of them are good solutions.
"In August, Holtec filed an appeal against the state’s ban on liquid radioactive discharges, in part claiming that the decision on whether or not to allow the discharge falls under federal not state jurisdiction.
"This, argue some opponents of Holtec’s discharge plans, is a stall and a distraction while it quietly gets on with the gradual evaporation of all the wastewater.
"'They’re using the appeal to buy themselves time,' Andrew Gottlieb, executive director of the Association to Preserve Cape Cod, told radio station WBUR. 'And what they buy themselves, with time, is the ability to continue to induce evaporation of the wastewater, so that ultimately it’s gone, at minimal cost to them.'
"Lampert agrees. 'Holtec can evaporate all the water to meet its schedule to dismantle the reactor building,' she said.
"In October, Lampert, along with other citizens representing the fishing, environmental, real estate and medical communities traveled to Boston to meet with staff in Massachusetts Governor Mary Healy’s office to demand that Healy’s administration call a halt to the evaporation.
"'There are laws on the books already that prohibit #AirbornePollution,' Diane Turco of #CapeDownwinders told the local NPR station after the Boston meeting. “And we’re asking our governor to immediately enforce those laws… She’s been very strong about no dumping in the bay. And we see this as a parallel assault on our communities,' Turco said.
"So far the governor has not taken action."

'This is our best option:' #Maine farmers turn to #SolarEnergy due to #contaminated fields
Story by Brad Rogers
7/25/2024ARUNDEL (WGME) – "#PFAS, also known as forever chemicals, have been nothing short of disastrous for hundreds of #Mainefarmers.
"It's ruined their land, made their cattle, milk and eggs unsafe to eat and left many farmers with serious health problems.
"'This farm has been in our family since 1914,' #FredStone, whose #Arundel farm was contaminated with PFAS, said.
"Stone was a third-generation dairy farmer in Arundel until forever chemicals were discovered in his fields, #WellWater, cows and milk.
"The pollution came from spreading #wastewater #sludge on his farm after the state told him it was safe.
"#MaineDEP has identified more than 500 sites where sludge was applied to farmland as #fertilizer.
"In 2017, Stone was the first farmer in the state to have his dairy farm and his pasture shut down due to #PFAScontamination.
"To make up for it, the state offered to buy his farm, but he refused to walk away.
"'We’re not in the farm selling or land selling business,' Stone said. 'Given what options we had left, that brought us to the solar thing.'
"He's been working with #WaldenRenewables to build a solar array on 100 acres of his contaminated farm.
"'It's their best alternative, but for some of these landowners, it's hard to kind of accept the change that they're facing,' Dale Knapp of Walden Renewables said. 'This is an injection of revenue that they desperately need.'
"This week, the Maine Public Utilities Commission [#MainePUC] approved new rules, paving the way for solar development on PFAS-polluted farms.
"'The Act provides that the commission must give a primary preference to projects that are located on contaminated lands,' Carrie Gilbert of the Maine PUC Commission said.
"'This is our best option,' Stone said. 'So reluctantly, very reluctantly I guess, that’s what we ended up having to do.'
"Stone plans to sign a 30-year lease for the solar array.
"After that, his farm may still be contaminated with forever chemicals, but 30 years is a long time for someone to come up with a solution.
"'That might mean that generational farm just goes on pause,' Knapp said. 'And the next generation may have the opportunity to return it to being a family farm someday.'
"'I’m very bitter,' Stone said. 'This is not the way we wanted to see this go. Yeah, I would love to see it continue on as a farm of some kind but damn the state of Maine for putting me in this position.'"
