Protecting springs from groundwater extraction: is a ‘drawdown trigger’ a sensible strategy?
By Matthew Currell – Senior Lecturer at RMIT University Springs, some of which have been flowing for hundreds of thousands of years, have been disappearing in Australia due to human water use over the past century. Following a hotly contested court case, Australia’s Environment Minister imposed a 20cm ‘drawdown limit’ at a set of springs, to protect them from a proposed coal mine. However, this ignores a fundamental principle of hydrogeology, known …

One hell of a great groundwater textbook now available free
‘Groundwater’ the seminar text book from Freeze and Cheery (1979) is free in pdf now…just follow the links here. This text book is almost as old as I am and important parts of modern hydrogeology are rusty or non-existent (like hydroecology amongst other topics) but it is still lucidly written and useful. I routinely send students to read chapters so I am happy that it is now available free. Kudos …

The new and exciting face of waterunderground.org
by Tom Gleeson I started waterunderground.org a few years ago as my personal groundwater nerd blog with the odd guest post written by others. Since I love working with others, I thought it would be more fun, and more interesting for readers, to expand the number of voices regularly posting. So here is the new face of the blog… What is the new blog all about? Written by a global …

Just in case you weren’t sure…groundwater flow around a fault zone is complex!
By Erin Mundy – a plain language summary of part of her Masters thesis Groundwater is the water that collects underground in pores and cracks in the rock. Understanding, protecting and sustaining groundwater flow is critical because over two billion people drink groundwater every day. The flow of groundwater can be impacted by geologic structures, such as fractures and faults. A fracture is a break in the rock; a fault …

Can we use an infrared camera to tell us how much groundwater is coming out of the side of a cliff?
By Erin Mundy – a plain language summary of part of her Masters thesis Groundwater is an important resource, with approximately 2 billion people around the world using groundwater everyday. Although most groundwater is beneath our feet, sometimes groundwater leaks out of stream-banks, hill sides and cliff faces – this is called groundwater seepage. Current scientific methods are not able to measure the amount of groundwater that leaks out of …

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 …

Tracking the Fallout and Fate of Fukushima Iodine-129 in Rain and Groundwater
This post is written by Matt Herod, and reposted here with permission… A recently published paper (by myself and colleagues from uOttawa and Environment Canada) investigates the environmental fate of the long lived radioisotope of iodine, 129I, which was released by the Fukushima-Daichii Nuclear Accident (FDNA). Within 6 days of the FDNA 129I concentrations in Vancouver precipitation increased 5-15 times above pre-Fukushima concentrations and then rapidly returned to background. The concentrations of 129I reached were never …

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 …

Water Canada article on our research
Scott Jasechko and I wrote an article for Water Canada about our research on modern groundwater published last fall in Nature Geoscience. We tried desperately to use plain language… how did we do? See WaterCanadaWinter2016
