“… [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…”

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.

Impact of River Morphology on River–Groundwater Exchange in Braided River Systems

--
H/T @thomas Wöhling | Professor at TU Dresden
“Do you like braided rivers? We think they are soooo beautiful. And they are interesting to study as well. Particularly how these complex and transient systems interact with regional aquifers…”
--
“Coupled models of two braided rivers with real, pre- and postflood event morphologies are studied for river–groundwater exchange changes…”
--
“Braided river systems are an important source for groundwater recharge, but their complex morphology makes river–groundwater exchange fluxes difficult to estimate. Their river channel morphology changes frequently after floods, which has effects on recharge rates that have rarely been studied in the past. This work aims to isolate the effects of changes in braided river morphology on groundwater recharge for two sections of the Wairau River and Waikirikiri River in New Zealand. For each study site, two different river morphology variants of a fully coupled surface water–groundwater model utilizing high-resolution DEMs of river bathymetry before and after a major flood event were set up while keeping parameterization and boundary conditions the same. The models demonstrate that flood-induced morphology changes in braided river systems alter groundwater recharge. [They] identif[ied] features, both simulated and observed, that explain the direction of change. Features that increase groundwater recharge are a larger braidplain aquifer extent and volume, larger wetted area and, specifically, an increase of areas with high exchange rates in locations of larger gradients between braidplain aquifer and regional aquifer. These factors influence groundwater recharge independent of connection (Wairau River) or disconnection (Waikirikiri River) of the system to the regional aquifer, albeit with different magnitudes. An extension of [their] research to other braided rivers is needed to more broadly generalize [their] findings...”

#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."

Drinking water protections:
By Ben Szalinski and Brenden Moore, Capital News Illinois
“Illinois Senate Bill 1723 bans #carbon #sequestration — the process of capturing and storing carbon by injecting it underground — within an area that “overlies, underlies, or passes through” a U.S. Environmental Protection Agency-designated sole-source aquifer. #EPA
The new law applies to the footprint of the #Mahomet #Aquifer, which is the main source of drinking water for more than 500,000 people across a 15-county area in central Illinois.
It comes as Illinois, especially downstate, is targeted for carbon sequestration projects due to the state’s favorable geology and the availability of federal tax credits.
Studies, including those conducted by researchers at the #universityofillinois have found minimal risk to water sources from sequestration activity.
But the legislation was a priority for central Illinois community #activists #environmental advocates and a bipartisan cadre of local lawmakers with zero risk tolerance due to the lack of a clear alternative water source if the aquifer were tainted.”

💧 Aggressive groundwater and the long memory of contamination
Even after more than a decade of monitoring, the groundwater in this carbonate aquifer remains undersaturated with respect to calcite — consistently showing negative SI values across nearly all observation wells.
This means that the system is still chemically aggressive toward limestone, slowly dissolving the host rock.
The impoundment, operating since 1976, continues to influence the aquifer — with the geometry of possible subsurface voids still uncertain to this day.📘 All supporting data and modeling results are included in the draft monograph:

💧 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.📘 Draft monograph: https://zenodo.org/records/16741148

🌎 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.
Two figures below show the modeled distribution of cadmium species across the aquifer and their evolution with dilution

🔬 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.📊 The image shows my preliminary zoning concept.
📘 All calculations and hypotheses are detailed in the draft monograph:

💧 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.

First-of-its-kind study finds 'secret #freshwater' that may stretch from New Jersey to Maine
This summer, a first-of-its-kind global research expedition followed up on that surprise. Drilling for fresh #water under the salt water off Cape Cod, #Expedition501 extracted thousands of samples from what is now thought to be a massive, hidden #aquifer stretching from New Jersey as far north as Maine.

CW: Massive ‘secret’ fresh water aquifer discovered under ocean floor
“
It’s just one of many depositories of “secret fresh water” known to exist in shallow salt waters around the world
…
“If we were to go out and start pumping these waters, there would almost certainly be unforeseen consequences,” he said. “There’s a lot of balance we would need to consider before we started diving in and drilling and exploiting these kinds of things.”

Lyon mystery: I initially thought this was an outdoor oven for baking very long baguettes, but the passage extends far into the hill at a slight incline so I'm wondering whether it is a water catchment gallery. The area is apparently riddled with them, some serving to drain the soil and prevent mudslides and building collapses (like the one that killed 40 in 1930), others to provide water for domestic use or fountains. Some catchments are early Roman but I have no idea when this one was built. Kind of strange there was no sign for curious tourists. Maybe it's just totally obvious to residents.

Groundwater ecology was one of the topics I was strongly considering to specialize in...
It is just *so* awesome what happens in these dark and completely overlooked ecosystems below our feet!
And thanks for pointing out the functions of these creatures! :ecoanarchism_heart:
Here, a nice introductory book, for if someone wants to nerd deeper:
"Groundwater ecology and evolution: an introduction" by Florian Malard, Christian Griebler and Sylvie Rétaux

“HIGHLIGHTS
• The regional pattern of IGF in west-central Florida is dominated by the characteristics of the Upper Floridan Aquifer.
• IGF plays a major role in the available water for partitioning and watershed aridity index.
• Groundwater pumping affects IGF, and the change in IGF counteracts the human impact on available water..."
