📺 WEBINAR - Characterizing the groundwater-surface water interface 📺 Join in this Wednesday when Paul McLachlan hands out early Christmas present in the shape of knowledge on how to characterize the groundwater surface water interface by means of #TEM. The groundwater-surface interface is crucial as it actively regulates the transfer of nutrients, contaminants, and water between #groundwater systems and #surfacewater environments. This presentation will focus on several examples utilizing land and water-based #TEM methods. These methods permit highly productive and detailed characterization of properties relevant to GW-SW exchanges. The first case study will cover land and water-based surveys in #Grindsted, Denmark to characterize groundwater pollution. The second will focus on land-based surveys to characterize alluvial deposits in #Zimbabwe and the third will focus on land and water-based surveys to characterize lake-GW connectivity in #South Africa. 📅 When: Wednesday, 5 PM CET 📺 Where: Online (Register free https://go.seg.org/46H1d5w) The talk is a part of the SEG HydroGeophysics series, where a number of HGG's researchers have the privilege of presenting our novel research and cases where we try to source clean water throughout the world. Stay tuned for talks by Anders Vest 💡 #ttem #floatem #skytem #ert #hydrogeology

We often focus on the land subsidence impacts of groundwater pumping in compressible aquifers. This paper addresses another negative legacy we're leaving future generations...inelastic aquifer compression resulting in reduced aquifer storage capacity. https://lnkd.in/gxYWRNVW

With the help of the Canadian Light Source (CLS), researchers from the University of Guelph have learned more about an emerging pollutant that is prevalent in groundwater across the Prairies. “Sulfolane is commonly used to treat sour gas, and there are large contaminant plumes across Canada, specifically in Alberta,” says Erica Pensini, Associate Professor at University of Guelph - School of Engineering. “We’ve been looking at how sulfolane migrates in groundwater, analyzing the risks to potable waters, such as wells, or other ecological bodies of water.” Pensini is particularly interested in how naturally occurring sulfates (salts) impact the movement of sulfolane in water and its ability to mix thoroughly with water. “Sulfolane plumes travel faster with fewer sulfates, so we're trying to clarify migration in the context of what can we do to tackle this contamination,” says Pensini. “How much time do we have? Where is it going? Which well should we protect?” Sulfolane has recently been linked to fertility issues in cattle and has been found in their milk. “We’re also partnering up with hydrogeologists and eco-toxicologists to explore other aspects that we’re not directly exploring in our lab,” says Pensini. Using the Brockhouse and SGM (Spherical Grating Monochromator) beamlines at the CLS, Pensini and her team have visualized the interactions between sulfates and sulfolane. What the researchers have learned about sulfolane can help inform remediation efforts. Their findings were recently published in the journal Physics of Fluids. “The CLS has been instrumental in understanding the behaviour of sulfolane,” says Pensini. “At the synchrotron we can probe aspects that we couldn’t probe anywhere else, so it is really, really important to us for this research.” https://bit.ly/3VUfQjk #environment #watersecurity #sourgas

Our most vital resource can also be our most precarious – fresh, drinkable water is at risk from drought, natural disasters, and other catastrophes. Geoscience is leading the way with a new generation of ocean water desalination solutions to help prevent water availability disruptions. 🌊 We pioneered subsurface slant well intakes for desalination projects to deliver reliable water quality and quantities with no impact on marine life, local groundwater basins, or reservoirs. Developed and refined over 18 years, leveraging 40 years of geohydrology innovation, and with California Coastal Commission approved projects in Doheny and Monterey, Geoscience’s subsurface slant well intake technology is leading the way to a sustainable future for California’s water needs. 💧 Get in touch to learn more about how Geoscience’s expert team of engineers, geologists and hydrologists help clients and communities with their full range of groundwater resources. https://gssiwater.com/ #geoscience #reliablepartner #engineering #desalination #greeneconomy #infrastructure #municipalities #hydrology #hydrogeology #environment

#Groundwater "A ‘global-scale’ study of groundwater levels by a team of researchers from the University of California at Santa Barbara (UCSB), ETH Zürich, University College London (UCL), Rutgers University and King Abdulaziz University was published on 24 January 2024 in Nature. The analysis is rooted in the analysis of millions of groundwater-level measurements in 170,000 wells from 1,693 aquifer systems in over 40 countries. Part of the data used for this study is now available in IGRAC’s Global Groundwater Information System (GGIS). Led by Scott Jasechko (UCSB), Debra Perrone (UCSB) and Hansjörg Seybold (ETH Zürich), the team spent years compiling and curating the dataset that led ultimately to the analysis of time series records (for at least 8 years) in 170,000 monitoring wells. For about 50% of these data, the responsible authorities, data owners or data providers have given approval to share them on the GGIS. In this dedicated viewer, users can browse over regions of interest, visualise the trend indicators calculated at the monitoring stations’ and aquifer systems’ levels, and consult the monitoring data charts. The dataset of Jasechko et al. (2024) combines data from a variety of sources, ranging from official groundwater monitoring networks to research studies. In comparison, the Global Groundwater Monitoring Network (GGMN), as a UN-supported programme, exclusively contains data collected and publicly shared by the countries. The article, Rapid groundwater decline and some cases of recovery in aquifers globally, confirms that groundwater-level declines are widespread in the twenty-first century, especially in dry regions with extensive croplands. Here, in regional aquifers underlying Iran, India, Spain, United States, Saudi Arabia, Morocco and Mexico median rates of groundwater-level decline exceed a metre per year. Worryingly, the study reveals an acceleration in rates of groundwater-level decline over the past four decades in 30% of the world’s regional aquifers. The analysis also notes that twenty-first century precipitation rates were lower than in the late twentieth century for most aquifer systems that exhibit an acceleration in groundwater-level declines. This could indicate a potential link between decadal-scale climate variability and climate change in accelerating groundwater-level declines either from reduced rates of groundwater recharge or increased water demand for irrigation. This widespread acceleration in groundwater-level declines highlights an urgent need for more effective measures to address groundwater depletion. Jasechko et al. (2024) also highlight some successful human interventions addressing groundwater depletion. For example, in Bangkok (Thailand), groundwater-level declines of the 1980s and 1990s were reversed following the implementation of regulations designed to reduce groundwater pumping. Meanwhile, in Albuquerque, New Mexico (USA), groundwater levels are recovering after an inter-basin .."
