    “… [The authors] analysed one year of drip water monitoring data from 46 monitoring sites across six karst regions in southeastern Australia. By integrating fast Fourier analysis, cross-wavelet transform and change point analysis, [they] identified five characteristic recharge behaviours and developed a conceptual framework linking temporal drip dynamics with recharge mechanisms. [They] hope this framework will contribute to a better understanding of recharge heterogeneity in karst systems and support future groundwater research under a changing climate…”

  2. What piece of shite to start the day on social media with. I ask you, what kind of #Grifting brainless entrepreneur would think that there is any sense in sucking up 40,000 megaliters of #water a year from an #aquifer in one of the driest parts of the land on the driest #Continent on earth to stand up an **Intensive** #horticulture business there?

    We haven’t seen anything as brainless as this since the Ord River Scheme and cotton industries up North in WA. What kind of madperson even think it is a responsible thing to do? The people behind *Future Agribusiness* are nothing but #NeoLiberal predators looking to profit while raping the land. They don’t give a toss about *Country* and the fragile *ecosystems* on land *Never Ceded* . But I do. In fact, the mojority of this society does care about the land and what is bieng done to it in the name of #NeoLiberalism and #NeoColonialism.

    Where is our *Environmental Protection Agency* in all this? Recovering from #Labor Govt death blows no doubt. There is no coming back from this kind of #pillage. Good grief, this is just insane. Here’s hoping the Courts (in reflecting the will of the broader society while adjuticating) will see true justice (in #fascist NT) applied to the benefit of all and not just a few madhats looking to cash up.

  3. #Australia - #KatherineNT residents say potential damages from #PFAS firefighting foam case should pay for further 'recompense'

    by James Elton, 1 June, 2026

    Excerpt: "PFASContamination in Katherine was first announced by Defence in 2016 — the result of decades of use of PFAS-containing firefighting foam at #Tindal, which sits above a large and interconnected #aquifer.

    "In the immediate aftermath, Katherine's town pool was closed and Defence trucked in bottled water.

    "Commonwealth to sue the manufacturer of a firefighting foam containing PFAS chemicals that contaminated 28 #DefenceForce bases across Australia.

    "A class action, settled in 2020, resulted in Defence paying $92.5 million to Katherine home owners and businesses to compensate for lost property value, as part of a broader class action that also included Williamtown in NSW and Oakey in Queensland.

    "Today, Katherine's town drinking water supply is thoroughly treated using a specialised plant to keep PFAS levels below minimum thresholds.

    "But residents with bores in the contamination zone are still advised not to drink their groundwater or eat eggs from chickens that drink water from the bores.

    "A 2018 health assessment commissioned by Defence also found there was an 'elevated risk' for anyone who ate fish caught in the #KatherineRiver on a regular basis, defined as one fish per week.

    "A Senate inquiry into the issue last year heard evidence that assessment had affected #Aboriginal people in the region, who had historically eaten large quantities and varieties of fish and crustaceans from the river."

  4. 💧 Beyond Diffusion: Groundwater as a Rock–Fluid System

    Contaminant plumes in groundwater are often seen as passive — just diffusion and advection through porous media.
    But what if we treat them as active geochemical fronts instead?

    In my recent modeling work, I describe contamination not as a mechanical process, but as a metasomatic transformation — a reaction zone between aggressive mine waters and carbonate aquifers.

    Each sector of the aquifer develops its own thermodynamic balance and mineral stability field.
    The plume itself becomes a chemical engine — reshaping host rocks, opening new pathways, and shifting the entire water–rock equilibrium.

  5. 🌎 Mapping dominant chemical speciation in a polluted carbonate aquifer

    In my recent modeling work, I modeled the dominant forms of element speciation in groundwater within a carbonate system.

    Beyond pure geochemical curiosity, this approach provides a practical lens:
    – it reveals where mineral precipitation is most probable,
    – and helps identify zones where remediation can be most effective.

    💻 Combining thermodynamic modeling (PHREEQC) with spatial analysis in R and QGIS turns subsurface processes into actionable insights for water-quality management and contamination mitigation.

  6. 🔬 Metasomatic Zonation as a Model of Groundwater Contamination

    One of the key theoretical bases in my research is the classical metasomatic zonation model (Korzhinskii, 1960s).

    I interpret the contamination halo formed by mine waters not as passive dispersion — but as an active metasomatic system, where aggressive fluids drive alteration and re-precipitation reactions within the carbonate aquifer.

    Highly mineralized mine waters create a complex interaction front.
    Thermodynamic modeling (based on well-monitoring data) allows identification of several geochemical zones partly analogous to Korzhinskii’s metasomatic sequence.

  7. 💧 Exploring how contaminated mine waters behave in a carbonate aquifer — through the lens of metasomatic zoning and thermodynamic #geochemical modeling.

    Using #PHREEQC simulations, data analysis in #RStats, and geospatial visualization in #QGIS, I’m studying how mine drainage transforms groundwater systems and mineral equilibria over time.

    📘 The draft version (v0.75) of my monograph on this topic has already been downloaded 550+ times on #Zenodo — showing how relevant this issue has become for both science and environmental policy.

    It’s independent research that links theory, modeling, and practical hydrogeochemical assessment — focused on the long-term impact of mine waters in the Kryvyi Rih region.

  8. Advocates demand halt to #uranium #mine near the #GrandCanyon

    #EnergyFuels says #nuclear power is necessary to fight #ClimateChange, but #Indigenous tribes fear losing their homes

    By Matthew Rozsa
    January 31, 2024

    "The Grand Canyon truly lives up to its name, being the largest canyon on Earth and one of the most popular national parks in America. But due to #UraniumMining in the area, some advocates are warning it could become the site of a future #EnvironmentalDisaster, which threatens to make one Indigenous village 'extinct.'

    "More than 80 groups signed onto a statement on Monday — representing Indigenous communities, scientists and environmental nonprofits such as the #SierraClub and the #CenterForBiologicalDiversity — directed at President #JoeBiden and #Arizona Gov. #KatieHobbs, demanding they close the #PinyonPlain uranium mine, which is located near the Grand Canyon.

    "'We have a choice in front of us. Allowing the Pinyon Plain mine to proceed is subjecting this landscape and its interconnected waters to a legacy of devastation and disregarding the rights of the #IndigenousPeoples on the land,' Sanober Mirza, Arizona program manager for the National Parks Conservation Association, said in the statement. 'Or we can choose a different path — one that holds a promise of protecting the Grand Canyon’s cultural sanctity, its people and natural resources.'

    "To understand why the mine's opponents feel so strongly, one can turn to #AmberReimondo, who work as energy director at a conservationist non-profit called the #GrandCanyonTrust. Reimondo explained to Salon by email that, on the one hand, #Biden permanently banned mining operations on nearly 1 million acres of federal managed lands by creating the #BaajNwaavjo I'tah Kukveni - Ancestral Footprints of the Grand Canyon National Monument in August 2023. Yet the Pinyon Plain mine was #exempt from this prohibition, and Reimondo argues that the impact on the region has been 'several fold.'

    "'What they've created here is a long-term, slow motion #EnvironmentalDisaster."

    "'The Grand Canyon region as a whole and especially the location of the mine, is deeply significant to Indigenous cultures and is a place where tribal members have conducted #ceremonies, collected medicine, hunted, and more, for centuries,' Reimondo said. 'The mine also overlies critical and complex [and] not well understood groundwater systems. One #aquifer in particular — the #RedWallMuavAquifer — is the sole source of water for the remote #HavasupaiVillage of #Supai inside the Grand Canyon. The mine poses a #contamination threat to these #groundwater resources not just today, but importantly, after the mine's mere 28-month operational lifespan has concluded and the mining operator 'cleans up' and moves on.'

    "Supai is so remote, it's only accessible only by helicopter or an 8-mile mule ride or hike, Reimondo explained, noting that if the newly-oxygenated groundwater comes into contact with nearby rocks, minerals like #arsenic and #uranium will be dissolved by the groundwater and enter aquifers used by the local community and essential to local ecology, including #HavasuFalls. Taylor McKinnon, Southwest Director for the Center for Biological Diversity, expressed similar concerns.

    "'Ultimately, this mine is going to require political leadership,' McKinnon told Salon in an interview, referring to both the Biden and #Hobbs administrations. 'Those administration's agencies have the authority to fix this problem if they so choose, and that's what they should do.'

    "We have detailed strenuously for years that neither regulators nor industry can ensure against the permanent and irretrievable damage to Grand Canyon's aquifers and springs," McKinnon added. "This mine was approved originally in 1986, under a record of decision from the US Forest Service under a presumption that it was highly unlikely that the mine would encounter groundwater, and further unlikely that if it did, it had the potential to contaminate deeper aquifers in the springs that they feed. Subsequent state permitting from the #ArizonaDepartment OfEnvironmentalQuality has basically parroted those same assumptions.'

    "Yet McKinnon alleges that in 2016 the mine punctured a perched aquifer, causing roughly 10 million gallons of water per year to drain into the mine workings. From there he asserts that a surface pond formed with water that has concentrations of uranium and arsenic far in excess of the Environmental Protection Agency (#EPA)'s water quality standards. Not only does this threaten the local endangered and endemic species, but it also impacts the nearby Havasupai tribe.

    "Havasupai means 'people of the blue-green water,' McKinnon said. "It's their longstanding cultural identity, and it is the water they drink, they farm with and that provides for all of their tourism economy because it is this just a beautiful series of massive verdant waterfalls that flow through the village and down into a series of waterfalls and pools where people camp and they derive tourism dollars.'

    "In a 2022 letter of opposition, the Havasupai Tribal Council, laid out what is at stake in the uranium mining controversy.

    "'Our identity as a people is intrinsically intertwined with the health of #HavasuCreek and the environment to which it gives life,' the tribe’s letter explained. 'We use this water for drinking, #gardening and irrigating, municipal uses, and #cultural and #religious uses. If the water source becomes contaminated like we have seen in other areas of Arizona due to uranium mining, we will no longer be able to live in our homes and Supai Village will become extinct.'

    "These fears are based on precedent. The nearby #NavajoNation is scattered with old uranium mines — over 500, in fact — awaiting cleanup, exposing locals to risk of '#LungCancer from inhalation of #radioactive particles, as well as #BoneCancer and impaired kidney function from exposure to #radionuclides in drinking water,' according to the EPA. Likewise, members of the #UteMountain #Ute tribe in #WhiteMesa, Utah have protested against uranium mines they say have contaminated local groundwater, air and even wildlife."

  9. 'It will poison everything.' #NativeAmericans protest #YuccaMountain #Nuclear Waste site

    by Ed Komenda, May 22, 2019

    "“Those transportation routes go through any number of sensitive habitats where a #derailment or a truck accident could cause significant impacts on water or on wildlife that live along those transportation corridors,' Donnelly [Nevada state director for the Center for Biological Diversity] said.

    "The office of #Nevada Attorney General Aaron Ford identified the complexity of waste transport as one of many reasons storing nuclear waste at Yucca Mountain does little to protect the #environment and people. Other concerns include national security (waste shipments as terrorist targets) and geology (Yucca's aquifer drains to the #AmargosaValley – home to more than 1,400 people and several #endangered species). [And is seismically unstable]

    "'#Contamination from Yucca Mountain could very easily contaminate the #aquifer,' Donnelly said, 'and thus contaminate all sorts of springs that harbor some kind of endemic life.'"
