Does Enhanced Mixing Improve Groundwater Quality? Evaluating the Impact of Injection-Extraction Engineering on Redox Conditions, Contaminants of Emerging Concern, and Antibiotic Resistance Genes  Open
Redox (reduction-oxidation) reactions play a crucial role in determining groundwater quality, as they strongly influence the behavior of Contaminants of Emerging Concern (CECs). The extent of mixing between electron donors and acceptors la…

The blind spot in water sustainability: why do we have such low desire for good water quality? Open
We review anthropogenic water pollution, and find that it is spreading in rivers and aquifers at an alarming rate. Actions advocated by the United Nations have thus far resulted in more improvements in water quality of surface water than t…

The fully implicit water mixing approach for the efficient simulation of reactive transport Open
Reactive transport is a phenomenon resulting from the interaction and coupling of solute transport and chemical reactions. A new method to solve reactive transport known as Water Mixing Approach (WMA) was introduced by Soler-Sagarra et al.…

Energy transition and the challenge of induced seismicity Open
Induced seismicity is likely a major obstacle in front of the widespread deployment of geoenergy applications, such as geothermal energy or geologic carbon storage (GCS), which are indispensable components of efforts to mitigate the climat…

Water Table Fluctuations Control Nitrate and Ammonium Fate in Coastal Aquifers Open
Coastal aquifers experience water table fluctuations that push and pull water and air through organic‐rich soils. This exchange affects the supply of oxygen, dissolved organic carbon (DOC), and nitrogen (N) to shallow aquifers and influenc…

Biofilm Growth in Porous Media Well Approximated by Fractal Multirate Mass Transfer With Advective‐Diffusive Solute Exchange Open
Biofilm growth in porous media changes not only the hydrodynamic properties of the medium (reduction in porosity and permeability, and increase in dispersivity), but also the transport itself (breakthrough curves display increasingly fast …

From the pore to the catchment-scale: a discussion of groundwater processes and modelling Open
Contrary to widespread belief, it is well known since ancient Greece that rivers flow most of the time because they receive groundwater discharge. However, it is less widely known that rivers are losing their base flow because of aquifer o…

Tracking biogeochemical processes in a Subterranean Estuary (STE): Application of a multidisciplinary approach integrating isotopes, hydrogeochemistry, and dissolved organic matter (DOM)  Open
Subterranean Estuaries (STEs) have been recognized for their role in the transport and fate of chemical compounds that discharge to the coastal ocean. The enrichment of coastal groundwater with nutrients is affected by different sources an…

Assessing the Fate of Benzophenone-Type UV Filters and Transformation Products during Soil Aquifer Treatment: The Biofilm Compartment as Bioaccumulator and Biodegrader in Porous Media Open
The fate of selected UV filters (UVFs) was investigated in two soil aquifer treatment (SAT) systems, one supplemented with a reactive barrier containing clay and vegetable compost and the other as a traditional SAT reference system. We mon…

A short review of the processes explaining water quality improvement during Soil Aquifer Treatment Open
Soil Aquifer Treatment (SAT) consists of recharging the effluents of wastewater treatment plants across the soil (possibly reinforced with a reactive layer), unsaturated zone, and aquifer. It has been known since long that a dramatic water…

Numerical modeling of hydraulic stimulation of fractured crystalline rock at the bedretto underground laboratory for geosciences and geoenergies Open
Hydraulic stimulation of Enhanced Geothermal Systems (EGS) aims at boosting permeability to facilitate fluid circulation, while keeping a low induced seismicity. However, some stimulations have led to poor permeability enhancement or too h…
