Monitoring groundwater drought without measuring it
Seventy-five percent of EU inhabitants depend on groundwater for their water supply, which makes groundwater management extremely important. To manage groundwater effectively during drought periods like 2015, data about groundwater levels are needed in (near-) real time.

Deep challenges: China’s ‘war on water pollution’ must tackle deep groundwater pollution pathways
As part of its recent ‘war on pollution’, the Chinese Central Government released a major policy on water pollution control and clean-up, called the ‘10-point water plan’ in 2015. The plan aims to deal once and for all with China’s chronic water quality problems.

Socio-hydrogeology: bridging the gap between science and society
Authored by Viviana Re, Marie Curie Research Fellow at Ca’ Foscari University of Venice, Italy Sustainability, integrated water resources management, climate change, groundwater governance. These are some of the currently trending topics in hydrogeology, as reflected by their widespread use as keywords in recently published literature. Indeed, hydrogeologists are at the forefront of guaranteeing the long-term sustainability of aquifers worldwide. But how can they assure that the outcomes of their investigations are …

Brackish groundwater resources: is development advisable?
Authored by: Grant Ferguson – Assistant Professor in the Department of Civil & Geological Engineering at the University Saskatchewan Groundwater makes up a large fraction of the Earth’s freshwater but that represents only a part of groundwater resources. Large volumes of groundwater are saline, with some reaching salinities of over ten times that of seawater. Brackish water is an intriguing part of the spectrum of groundwater resources, sitting just beyond the water quality salinity requirements …

The great American groundwater road trip: Interstate 80 over the Ogallala Aquifer
Authored by: Sam Zipper – Postdoctoral Researcher in the Department of Civil & Environmental Engineering at the University of Wisconsin-Madison In late July, my wife and I loaded the dog into the car, cranked up the water-related tunes, and drove over a few million cubic meters of water. No, we haven’t traded in our sedan for an amphibious vehicle – rather, we were driving west, across Nebraska, on the …

What caves can teach us about climate, past and present
Authored by: Gabriel C Rau, Associate Lecturer in Groundwater Hydrology at UNSW, Australia Andy Baker, Director of the Connected Waters Initiative Research Centre at UNSW, Australia Mark Cuthbert, Research Fellow in Hydrogeology at the University of Birmingham, UK Martin Sogaard Andersen, Senior Lecturer at UNSW, Australia Have you ever enjoyed the cool refuge that an underground cave offers from a hot summer’s day? Or perhaps you have experienced the soothing …

Baseflow, groundwater pumping, and river regulation in the Wisconsin Central Sands
By Sam Zipper, postdoctoral fellow at Madison and author of tacosmog.com We often think of groundwater as a nonrenewable reservoir, deep underground, and with good reason – less than ~6% of groundwater globally entered the ground within the past 50 years. However, where a river or stream intersects the water table, water is able to move from the aquifer to the stream (or vice versa). This supply of shallow groundwater …

Nature Geoscience digging into water underground this month!
Nature Geoscience is digging hard into water underground – the February issue is part of a special focus on groundwater. The cover this month is a gorgeous (groundwater-filled?) waterfall by Glen Jasechko, Scott’s brother. The groundwater focus includes: commentary on drought in the Anthropocene, led by Anne van Loon news and views pieces by Ying Fan and Tamara Goldin our paper on the volume and distribution of modern groundwater a …

Groundwater is NOT photogenic!
One of the first things I realized when designing this blog was that groundwater is not photogenic, in the extreme. Seriously: I dare every hydrogeologist to go to google images and search ‘groundwater‘. You find something like this: I am not saying that I dislike conceptual models or think they are ugly. I actually quite like them, which maybe explains my current profession! But I do think in our image-obsessed, …

Is groundwater depletion keeping California fruit and veggies cheap during the severe drought?
Food prices in the United States are increasing slightly but not as significantly as one might expect given the severe drought in California. Margret Munro, a science journalist with Postmedia, recently asked me a great question: is groundwater depletion keeping California fruit and veggies cheap during the severe drought? Following up on her article, here is what I found and what it means for the Central Valley aquifer system in …
