  1. This should be more widely known

    Years and years ago Munich realised that paying farmers to transition to organic agriculture was much, much cheaper than building filtration plants to remove agrochemicals from the water supply

    Why don’t we all do it?

  2. 🧪 Aquatic zinc speciation modeling across the Inhulets River (September 2025) highlights why total metal concentrations fail to reflect true ecotoxicity:

    ☝️ Key Hydrogeochemical Trends:
    🔹 Free aqua-ion (Zn²⁺): Dominates at most stations (57–64%). This fraction is the most bioavailable and drives aquatic toxicity.
    🔹 Carbonate complex (ZnCO₃⁰): Secondary background form (18–24%), facilitating conservative transit migration.
    🔹 Sulfate complex (ZnSO₄⁰): Consistently 6–11% due to elevated background sulfate mineralization.
    🔹 Shift at Sample Point 6_1 (pH 8.66): Alkaline buffering radically alters speciation—free Zn²⁺ drops to 32%, while ZnCO₃⁰ becomes dominant (49%) alongside rising ZnOH⁺ (8%).

    Methodology:
    ⚙️ Speciation: PHREEQC (Thermoddem database)
    ⚙️ Pipeline & Dataviz: R (tidyverse, ggplot2)
    ⚙️ Minor species (<0.5%) aggregated into "Other" (Інші форми).

    “Are global river flows no longer natural? Can we really talk about natural rivers? [The authors] started asking ourselves these questions a few years ago over wonderful discussion sessions.
    [They] argue that global river systems have entered a new phase, one of Anthropogenic River Flows, where flow regimes arise from the persistent interaction of:
    • the physical alteration of river systems,
    • the institutional and socio-technical organisation of water use and allocation
    • broader global and systemic processes operating across scales.
    In the Anthropocene, these domains do not operate independently because a change in one alters how the other two function. Global water risks and river flow properties then become an emergent property of these interactions.
    As a result, [the authors] call for a rethinking of how we study, understand, and manage river flows to better reflect this new reality…”

  5. Why swimming in the Rhine is allowed in Switzerland but banned in Germany.

    Basel has spent decades making the Rhine safe for swimmers, while German cities are imposing bans.

    Could a growing European push to reclaim urban waterways change that?

  11. #SanfordME City Council extends #DatacenterMoratorium 180 days amid resident concerns

    by WGME Staff
    Tue, August 4, 2026

    SANFORD (WGME) -- "Sanford city councilors have voted to extend the city's moratorium on new #datacenters for another 180 days.

    "The previous moratorium was approved in May and was set to expire.

    "The extension comes as a developer proposes building a 1,000-acre data center along the #MousamRiver.

    "City leaders and residents have raised concerns about potential impacts on #WaterQuality, #LandUse, #ElectricityDemand and other #Environmental issues.

    " 'We have the chance to protect the #community, #wildlife and the legacy of the Mousam River, not diminish its value by allowing harmful projects of this scale to be built along the river,' said Eve Dumont-Wilson, who opposes the project."

  13. 📰 NC Coastal Habitat Protection Plan Update Begins

    🌊 North Carolina environmental officials have started updating the state's Coastal Habitat Protection Plan (CHPP), a long-term strategy focused on protecting coastal habitats that support fisheries, water quality, and the seafood industry.

    🌿 The 2026 update is centered on three priorities: ecosystem-based habitat management, seagrass protection and restoration, and planning for long-term wetland changes along the coast.

    🤝 State agencies and stakeholders are helping develop draft recommendations that will eventually be released for public review, shaping future coastal conservation and resource management efforts.

    “… [U]rban floods are not merely hydraulic events; they also transport sewage, pathogens, and other contaminants across streets and communities, leading to significant public health risks…
    How do we quantify microbial contamination in near real time during a flood event, when emergency conditions make field sampling unsafe, sparse, or even impossible?...
    [The authors] explored whether Earth observation data, combined with machine learning, could bridge this critical monitoring gap. By combining Landsat-derived water surface temperature, machine learning, a coupled MIKE+ Flood–ECO Lab hydrodynamic–ecological model, and Quantitative Microbial Risk Assessment (QMRA), [they] estimated microbial concentrations (𝘌. 𝘤𝘰𝘭𝘪), simulated their fate and transport during floods, and quantified the associated human health risks.
    The takeaway: predicting flood risk isn't just about where the water goes; it's about what it's carrying and who it puts in harm's way. Earth observation and machine learning can help close that gap when it matters most, during the emergency, not weeks after…”

  15. The Red River of the North floods differently — it flows north into ice, across a lakebed-flat valley. I've been studying its floods and, lately, how spring cryo-pulses move PFAS through the system.

    Water quality is where I started: my PhD fused hyperspectral remote sensing with in-situ data to estimate nutrient loads in the Shenandoah. Rivers keep handing me the best problems.

  16. Busy Beavers - The Turbidity Signature Of Ecosystem Engineers At Work

    H/T @alan Puttock
    “Beavers are the quintessential ecosystem engineers. In slow-flowing streams, they create complex wetlands with ponds by building dams and canals that can positively impact biodiversity, hydrology and water quality. These activities can interchangeably capture or release sediment along the watercourse. To date this has not been quantified at the resolution of rainfall events or beaver activity. This study used 15-min frequency, sustained monitoring upstream and downstream of a newly establishing beaver wetland to measure episodic changes in water turbidity at an event resolution. Monitoring showed no significant differences between upstream and downstream turbidity over 160 days when the first pair of beavers, known not to be building dams or canals, were resident. Shortly after introduction of another beaver pair, however, dam building, burrows and canal excavations were quickly observed, resulting in the creation of a complex beaver wetland between 2021 and 2024. Monitoring over 375 days during this period showed significant differences. Downstream turbidity was significantly higher overall than upstream: 13.1 Nephelometric Turbidity Units (NTU) compared to 4.2 NTU. Stochastic spikes in downstream turbidity during the study period not recorded upstream were associated with dam building and burrowing. Overall, there was no significant difference in turbidity loads, which was at least partially explained by a reduction in discharge downstream, particularly in higher flows, during the dam building period. This demonstrates a complex system with the trapping of influent sediment, the storing of water and the periodic release of beaver wetland sediment leading to net balance in loads. These results help provide context for other studies which have used temporally discrete sampling campaigns rather than continuous high-frequency monitoring. They provide a unique insight into the downstream impacts of a rapidly developing beaver wetland over its first three and a half years in a landscape that hasn't had beavers for over 400 years…"
