  1. #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.

  2. 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.

  3. Happy to see our newest publication out in Water Research doi.org/10.1016/j.watres.2026.

    We establish bacteria from the genus Novosphingobium as model organisms to study bacterial mechanisms for removing #micropollutants in activated carbon filters.

  4. The Conversation: How sewage treatment plants could handle food waste, sparing landfills and the climate . “When we compared greenhouse gas emissions for the same food waste composition, we found that sending food to a landfill would emit 58.2 kilograms (129 pounds) of carbon dioxide equivalent per ton of food waste. In comparison, we looked at a conventional wastewater treatment plant, the […]

  5. #Okra and #Fenugreek Extracts Safely Remove #Microplastics From Water in New Texas Research

    May 10, 2025

    "The substances behind the slimy strings from okra and the gel from fenugreek seeds could trap microplastics better than a commonly used synthetic polymer.

    "Texas researchers proposed in 2022 using these sticky #NaturalPolymers to clean up water. Now, they’ve found that okra and/or fenugreek extracts attracted and removed up to 90% of microplastics from #ocean water, #freshwater, and #groundwater.

    "With funding from the U.S. Department of Energy, Rajani Srinivasan and colleagues at Tarleton State University found that the plant-based polymers from okra, fenugreek, and #tamarind stick to microplastics, clumping together and sinking for easy separation from water.

    "In this next stage of the research, they have optimized the process for okra and fenugreek extracts and tested results in a variety of types of water.

    "To extract the sticky plant polymers, the team soaked sliced okra pods and blended fenugreek seeds in separate containers of water overnight. Then, researchers removed the dissolved extracts from each solution and dried them into powders.

    "Analyses published in the American Chemical Society journal showed that the powdered extracts contained #polysaccharides, which are natural polymers. Initial tests in pure water spiked with microplastics showed that:

    - One gram of either powder in a quart (one liter) of water trapped microplastics the most effectively.
    - Dried okra and fenugreek extracts removed 67% and 93%, respectively, of the plastic in an hour.
    - A mixture of equal parts okra and fenugreek powder reached maximum removal efficiency (70%) within 30 minutes.
    - The natural polymers performed significantly better than the synthetic, commercially available polyacrylamide polymer used in #wastewater treatment.

    "Then the researchers tested the plant extracts on real microplastic-polluted water. They collected samples from waterbodies around Texas and brought them to the lab. The plant extract removal efficiency changed depending on the original water source.

    "Okra worked best in ocean water (80%), fenugreek in groundwater (80-90%), and the 1:1 combination of okra and fenugreek in freshwater (77%).

    "The researchers hypothesize that the natural polymers had different efficiencies because each water sample had different types, sizes and shapes of microplastics.

    "Polyacrylamide, which is currently used to remove contaminants during wastewater treatment, has low toxicity, but its precursor #acrylamide is considered #toxic. Okra and fenugreek extracts could serve as #biodegradable and #nontoxic alternatives.

    " 'Utilizing these plant-based extracts in water treatment will remove microplastics and other pollutants without introducing additional toxic substances to the treated water,' said Srinivasan in a media release, 'thus reducing long-term health risks to the population [and the environment].

    "She had previously studied the use of food-grade plant extracts as non-toxic flocculants to remove textile-based pollutants from wastewater and thought, ‘Why not try microplastics?’"

  6. "The Boring Company has applied to discharge 143,000 gallons of treated wastewater daily into the Colorado River near my home. I'm concerned they will not follow the terms of this permit.

    They have already received multiple environmental violations and public records show that they are not working with regulators in good faith. "
