Crowdfunding Science: What worked and what didn’t, who pledged and how did we reach them?

Part two of three in a Crowdfunding Science series by Jared.

___________________________________________________________

During March of 2017, myself and a group of students supervised by Dr. Jodie Miller of Stellenbosch University’s Earth Science department (South Africa) completed a 5-week long crowdfunding campaign. The Campaign raised R149 899.00 (€9800) from 120 backers that were both local and international. The campaign used several different mediums to attract potential backers. In this blog I will summarize what engagement methods we used and which ones worked the best.

Before I do this, I have also partitioned backers into three categories that describe to what degree they are separated from myself and the campaign team. Category 1 includes members of family, colleagues and close friends, that would likely contribute to your fundraising campaign regardless of how you marketed it or if they were confident you would succeed. Category 2 included people that myself or the campaign team either are acquainted with, have met before or have been suggested to us by a member of category 1. Category 3 backers are those that myself or my research team have no prior connection to and have been made aware of the campaign through 3rd party methods.

Half of backers fell into category 2 with the other half almost evenly distributed between categories 1 and 3. The distribution of funding received showed a similar distribution with a slightly skewed distribution toward category 3 backers contributing on average more than category 1 backers.

Engagement methods showed some interesting outcomes with direct contact contributing half of the backers as well as half of the funds raised, social media methods, which included Facebook, Instagram and Twitter, contributed the next largest portion of backers (a quarter) but was trumped by word of mouth backer’s average contribution amount. The remaining contributors were those who found out about the campaign through radio/newspaper interviews/articles, internet news and anonymous contributors for whom I have no data (Unknown).

Upon the completion of the campaign, backers were contacted to give feedback on what they believed was effective in the marketing strategy of the campaign. Although radio interviews did not produce a large amount of backers and funds, they produced the largest proportion of category 3 backers.

The data presented above only mentions the successful methods of engagement. In addition, there were several other attempts at fund raising that were somewhat less effective. These included: handing out flyers and putting up posters on campus and surround areas, approaching funding institutions as well as water related government and private entities for support and using mailing robots to send generic emails to large mailing lists.

Before the campaign had ended myself and two honours students had already left on our field sampling trip. In the final part of this blog series, I will break down, what we raised the funds for, what the groundwater sustainability project is trying to accomplish, and what has culminated as a direct result of postgraduate science crowdfunding.

A cool new collectible: Water

A cool new collectible: Water

Post by Matt Herod, Waste and Decommissioning Project Officer for the Canadian Nuclear Safety Commission, and Adjunct Professor in Earth and Environmental Science at the University of Ottawa, in Ottawa, Canada.

_______________________________________________

I have always been a mineral and fossil collector. It was a hobby that stuck and blossomed into a career. I still collect minerals and fossils, although I’ve now added rocks from my field sites to the collection. One thing I should note is that for inanimate, immobile objects it is shocking how quickly rocks can colonize parts of a house, garage, basement, etc.

However, since my early years in geology a very large part of my day is concerned with water; my PhD was almost exclusively about water. Water is my focus and it is truly fascinating. So that got me thinking. Why don’t I collect water?

You may think water is all the same. Turn on the tap, it comes out, drink, wash, whatever. It’s just water. Well, you could not be more wrong. Water is different and changeable. Plus it fits in a small bottle. In short, the perfect collectible.

But maybe you’re not convinced to start collecting water just yet.

Water has types, an identity, just like people. You may be familiar with the notion of people’s personalities being Type A’s, B’s and C’s. Although the types of water are a little more nuanced. That said, so are the types of people.

Water is sorted into types based on its chemistry. The chemistry of water comes from the dissolved salts within it and the relative concentrations of those salts. The isotopic composition of water can also be used to identify its type. Some water types are classed based on their heritage. For example, water found in pore spaces deep underground is often called brine, the precursor to that brine is, or often was ancient ocean water.

Let me give you some examples of water with interesting identities. One thing I should mention is that many of the ways waters are typified only consider their dissolved salt concentration, however, when you factor pH, Eh, and isotopic variation of the many, many different isotopes the number of water types balloons exponentially. For example, a water with a pH of 6 and a total dissolved solids (TDS) concentration of 500 ppm can have isotopic ratios, age and origin totally different from another water with the same pH and TDS. Like I said, it gets complicated fast.

To start with an easy one:

Seawater: Not only is it familiar, it is pretty important given that 97% of Earth’s water is this type and a significant percentage of Earth’s biomass lives in it. Seawater is about 3.5% saline and one of the most interesting features of the water is that it is pretty much everywhere and chemically very consistent. There are differences in the composition of seawater in the certain places around the world, for example, in restricted basins salinity can be higher or where fresh water enters the ocean in a river delta or estuary salinity is lower. Isotopically seawater is also interesting. Not because it has an unusual isotopic composition, but because seawater has been set as the standard to which all other water is compared. It is the zero point that stable isotopes in all other water is measured against.

Glacial Water: Of the 3% of Earth’s water left after the oceans, 69% is frozen in glaciers. To condense the characteristics of glacial water into one word I’d say clean. It just doesn’t have much in it. The reason for this is that glacial water started its days as precipitation, which is water that was evaporated from a water body and condensed. The evaporation process removes almost all of the dissolved solutes. Therefore, there just isn’t much stuff in glacial water besides the H and the O. That doesn’t mean glacial water is boring though. There is still a lot that if can tell us. For example, the variations in O isotopes can be used to reconstruct past temperatures and gases trapped in the ice can tell us about the composition of past atmospheres as well. The information we get from glacial water is different, but extremely valuable!

Brine: Do not drink a brine. You WILL regret it. I do not speak from experience, but frankly if almost 30% of the fluid is salt, it simply isn’t drinkable. Brines come in a lot of flavours, and technically if it has >5% salt it’s considered brine. However, I have encountered some brines that are over 30% saline. Of course, they were not drinkable as they were porewater in a sedimentary basin. However, there are some extremely salty bodies of water out there as well. Brines are interesting because they have so many stories to tell. There is history there, recorded by the solutes, gases and isotopic composition of the brine that explains how it became more than a simple water and transcended the label of water entirely to become much, much more…a fluid. Typically brines in nature have a history that involves salt dissolution leading to high concentrations of Na and Cl. However, other types may simply be evaporated seawater causing all of the dissolved ions to become more concentrated. For example, brines often have high concentrations of Ca, Br, I, Sr, etc, etc. Isotopes in brines also reveal a lot about their past and can distinguish if a brine is a glacial water that has dissolved salt, or is evaporated seawater or has a hydrothermal component. There is just always more that you can find out about brines.

High and low pH waters: pH plays a huge role in dictating the chemistry of water and the dissolved salts therein. Around the world there are naturally occurring waters that have incredibly high and low pH’s. The low pH waters, typically around 1-3 on the pH scale, occur in areas where natural acid rock drainage is happening. Acid rock drainage, aka. ARD, happens when sulphide minerals, often pyrite, oxidize releasing sulphuric acid leading to seeps with exceedingly low pH’s. On the other hand, high pH waters occur more rarely. Alkali springs occur when water comes in contact with hydroxide minerals, such as calcium hydroxide. Hydroxides form in dry, arid environments or where organics and limestone have been heated and burned such as areas with volcanic activity. One famous alkali spring is the Maqarin site in Jordan where water with pH’s from 11-13 occur!

Hydrothermal waters: HOT, HOT, HOT! These waters are absolutely loaded with interesting chemistry. Spewing out of hydrothermal vents on the seafloor at temperatures of up to hundreds of degrees Celsius with tons and tons of dissolved metals like copper, lead, gold, zinc, silver, etc. Furthermore, many of the world’s metal deposits are related to the movement of hydrothermal fluids within the crust. Hydrothermal fluids get their heat from the mantle or magma chambers within the crust. As they are heated they dissolve the rocks in contact with then leading to highly enriched solute concentrations and then when they discharge and cool, the solutes precipitate leading to black smokers, or mineral precipitates in fractures in the crust.

Young and old waters: My last Water Underground post discussed this in more detail. Suffice it to say when you start analyzing carbon-14, tritium, chlorine-36, iodine-129, krypton-85 and 81, etc. you can find waters ranging in age from just a few years to tens of millions to billions of years old. Each of these, is worthy of a spot on my shelf that is for sure. Excitingly, each of these waters has a story to tell about its origin and experiences over the years. Analyzing these isotopes and putting them in context with the geologic history of where the water is found can explain a lot about the regional hydrologic cycle and how water recharges, and discharges and how vulnerable the aquifer it is housed in is to contamination or over-pumping.

This is just the tip of the iceberg (see above). There are many ways water is sorted into types, often called “facies”, which are then plotted graphically. Here is a nice paper that compares some of the different ways of plotting water [1]. Read all the way to the end an you’ll be rewarded with a somewhat strange smiling face.

Anyway, hopefully I’ve convinced you to grab a bottle and collect a sample or two when you come across an interesting water!

Finally, my only piece of advice if you’re going to start a water collection…make sure the top is screwed on tight.

From groundwater flow to groundwater glow: why does groundwater fluoresce in ultraviolet light?

From groundwater flow to groundwater glow: why does groundwater fluoresce in ultraviolet light?

Post by Andy Baker, Professor researching groundwater, caves, past climate, organic carbon and more at the University of New South Wales, in Australia.

__________________________________________________

We often come across items that glow after being exposed to ultraviolet light. Fluorescent stickers can be bought for the ceilings of bedrooms; fluorescent hands on analogue clocks and watches; fluorescent markings on a car dashboard.

In all these examples, there are organic molecules that absorb energy in the form of ultra-violet light and can then re-emit that energy, in this case as visible light. We are talking fluorescence. Or when the emission of light is delayed, phosphorescence. It requires loosely-held electrons to be present in a molecule. The energy provided by ultraviolet light can excite these electrons to a higher energy level, and when the electrons return to a lower energy level, light is emitted. This emitted light has to be at a longer wavelength than the excitation energy, and if it occurs at wavelengths our eyes can detect, then we can see it. Hence the blue-green colours of watch hands and plastic ceiling stars.

What about groundwater? It’s the same process: if we shine ultraviolet light at groundwater samples, then they fluoresce due to the presence of organic molecules that are often present. Unfortunately, we can’t see any of this fluorescence with our eyes, as it is emitted in the middle- and long-range ultraviolet, so we must use detectors that can ‘see’ at these wavelengths. But that is relatively easy – charge coupled devices (CCDs), the same as you would find in a digital camera, detect in the ultraviolet. And we can add in improved light emitting diode (LED) technology, which can now produce higher-energy, shorter-wavelength ultraviolet light to excite fluorescent molecules. It’s the same technological improvement that means that you can now buy blue LEDs to decorate your house – have you noticed how they have become increasingly available – and potentially keeps you awake at night.

Why does groundwater glow in ultraviolet light? Firstly, it could be from natural organic matter. Organic matter is transported by rivers, which may be recharged to groundwater where rivers are ‘losing’. Or it might be leached from the overlying soil during rainfall recharge of groundwater. Or it might be desorbed from sedimentary material in the aquifer. Natural organic matter fluorescence tends to occur at longer ultraviolet wavelengths (360-400 nm) and provides a convenient way of detecting dissolved organic matter.

Secondly, groundwater samples might fluoresce due to the presence of microbial matter. In rivers and wastewater systems, the amount of fluorescence at shorter ultraviolet wavelengths (300-350 nm) has been observed to correlate with the amount of oxygen being consumed (the biochemical oxygen demand, or BOD). It is not possible to distinguish between individual or groups of microbial species, and researchers are still investigating exactly what is fluorescing. However, recent research has shown that there is significant potential in using hand-held fluorescent probes to determine microbial water quality in groundwater. Where there might be faecal contamination of groundwater used for drinking water supply, there is great advantage to this method as an immediate reading is possible in comparison with other methods which typically take 18-30 hours.

Thirdly, groundwater which is contaminated by organic matter may be detected if enough of the contaminant is fluorescent. For example, fluorescent whitening agents, also known as optical brighteners, may be added to detergents, shampoo and paper products to make items appear whiter.  The molecules are designed to emit light at the blue-violet end of the visible light spectrum, and it counters any yellowing of aging fabric, paper or hair. Hence your clothes appear whiter, your hair blonder. Fluorescent whitening agents are removed during wastewater treatment and degrade in sunlight. But in the case of unlined landfill sites, fluorescent whitening agents can persist in contaminant plumes in the groundwater, making them a useful tracer.

So why does groundwater glow in ultraviolet light? It is all to do with any fluorescent organic matter that might be present in groundwater. And thanks to improvements in technology, we can now make measurements of this fluorescence using portable and handheld probes, in-situ, and rapidly. Increasingly adopted by surface water quality researchers and water engineers, is it time for the groundwater community to move on from groundwater flow to groundwater glow?

A Tanzanian groundwater safari through the last 2 million years

A Tanzanian groundwater safari through the last 2 million years

Post by Mark Cuthbert, Research Fellow and Lecturer at Cardiff University, in the United Kingdom, and by Gail Ashley, Distinguished Professor at Rutgers University, in the United States.

_______________________________________________

During the dry season, Lake Masek in Northern Tanzania (see map) is a lovely place to be if you’re a hippo or a flamingo, but for humans it’s an inhospitable environment. We were on ‘safari’ (a scientific one of course, but the wildlife was a massive bonus! Photo 1-left) to try and better understand the distribution of freshwater in this dryland landscape.

Map: Locations on our groundwater safari in Northern Tanzania.

Watching our backs in case of predators, we ventured out of the safety of our Land Rover for Gail to sample the lake water, as salt blew in drifts around us off the desiccated edges of the lake bed (Photo 1-right). It was very salty and not potable for humans. All the streambeds that run into the lake were dry and yet our Masai guide told us that nearby we could find freshwater all year round.

Photo 1: (L) The amazing wildlife in the Ngorongoro Crater & (R) Saline-alkaline Lake Masek.

Intrigued, we set off around the edge of the lake and as we came over the crest of a small ridge were met with the most remarkable site – 1000s of cattle and goats queuing up for water from pools on the edge of the dry river valley just downstream of the lake. We waited for the queues of animals to die down and asked permission from the local guardians of the water source to investigate (Photo 2). The pools turned out to be fed from groundwater flowing out of rocks at the side of the valley. In contrast to the salty water from the adjacent lake, these springs were fresh and potable. We think the water is very old having originally fell as rain on the flanks of the ancient Ngorongoro Highlands (see map) before flowing slowly under gravity through layers of volcanic rocks 10’s of km to the springs. Because there’s so much groundwater stored in these rocks, and because they are not very permeable, the water seeps out quite slowly. So the springs keep running all through even the longest droughts and are vital water supplies for local people.

Photo 2: Asking permission to sample at Eremet springs

We travelled east along the same dry river valley in which we’d encountered the springs. Here the river, which only flows during the wet season, has cut itself into a steep ravine called Olduvai Gorge. We walked down the side of the gorge travelling back in time ~2 million years, the rocks and sediments around us telling a well-documented story of how the environment has changed over that time. Many exciting fossil discoveries have also been made in the gorge including some of our oldest human ancestors (Photo 3-left). For us one of the most interesting discoveries was geological evidence of ancient springs (Photo 3-right) found in the same layers as fossil human ancestors and stone tools which Gail has documented going all the way back to nearly 2 million years ago (read more here). There are clues from the surrounding sediments that there was a lake nearby but it was salty and alkaline, and we think the springs would have kept flowing for 100s or even 1000’s of years during persistently drier periods experienced in the past (read more here).

The springs that were flowing in the Olduvai area 2 million years ago, just like the springs on the margins of present day Lake Masek, would have been the only freshwater for miles around and vital for sustaining life during dry periods. Since there are hundreds of freshwater springs dotted around present day drylands in the East African rift system, we can hypothesise that during dry periods in the past, similar locations would have acted as ‘hydro-refugia’ – places where animals could find the necessary freshwater for survival in an otherwise dry landscape. In dry periods there would be lots of competition for these resources and populations would have become isolated from each other for quite long periods. During wetter periods springs would have enabled our ancestors and other species to move long distances across the East African landscape and beyond, acting like stepping stones connecting river corridors and lakes and enabling populations of different species to encounter one another (read more here). Groundwater was likely therefore an important control on the movement and evolution of humans in this environment.

Photo 3: (L) Paranthropus boisei (‘Zinj’) hominin skull found at Olduvia gorge (Photo Credit: Tim White PhD, Human Evolution Research Center, University of California, Berkeley) & (R) Mark Cuthbert next to a tufa (calcium carbonate) deposit thought to be evidence of groundwater discharging near the site that the Zinj fossil was found.

Groundwater is often ‘out of sight and out of mind’. Our safari gave us a glimpse into its importance in sustaining life in a dryland environment not just in the present day, but also for our ancestors going back at least 2 million years through some climatically turbulent periods. The challenge going forward is how that groundwater resource can be protected to make sure it’s there when it’s needed in the face of an uncertain climatic future.

Acknowledgements: it has been a massive privilege to be able to explore this landscape and ponder how freshwater has shaped life here over millions of years. Particular thanks to our guides Joseph Masoy and Simon Matero, logistical support from Charles Musiba (LOGIFS – Laetoli-Olduvai Gorge International Field Camp) and TOPPP (The Olduvai Paleoanthropological and Paleoecological Project), our hosts at the Ngorongoro Conservation Area Authority, and all our collaborators on the papers cited.

Inspired by the famous list of unsolved math problems (hence the header image), the International Association of Hydrological Sciences has an interesting challenge for us all: define 23 unsolved problems in hydrology:

The International Commission on Groundwater is going to submit a few problems via the LinkedIn forum. A few of us at Water Underground are going to put our thinking caps on and submit a problem or two. If you would like to be part of the discussion very early in 2018, get in touch with Tom Gleeson.

On the social responsibility of water scientists

On the social responsibility of water scientists

Post by Viviana Re, a post-doctoral research fellow at the Department of Earth and Environmental Sciences of the University of Pavia, in Italy.

_______________________________________________

Should we feel a moral obligation to engage, if our work has real implications on society?

As an environmental scientist, with a PhD in Analysis and Governance of Sustainable development, I grew up “multidisciplinary-minded’ and the three-pillars of sustainability soon become my bread and butter.

However, as I progressively specialized in hydrogeology I had to confront myself with a new world, more technical, definitely interesting, but perhaps a bit suspicious with social sciences (at least some years ago), and where “no quantitative data” was often considered as a synonym of “no substance”.

When, back in 2013, I first presented the concept of socio-hydrogeology at an international congress on hydrogeology I divided this world in two. Some people definitely loved this new approach and found a lot of similarities with their work and research interests. Others, more skeptical, asked me if I decided to quit SCIENCE and dedicate myself to politics instead.

Besides the fact that I generally prefer to be pleased than criticized, I admit I am sincerely grateful to all those who shared with me their perplexities as they made me realize that:

  • I should improve my communication skills;
  • I shouldn’t take anything for granted – multidisciplinary and integrations are the roots of my research but this may not be the case for everyone;
  • I should better engage in promoting the incorporation of the social dimension into hydrogeological sciences and in fostering the connection between science and society.

These things follow from my belief that, as scientists, we should all have a key role in ensuring that the results of our hard work are really used to foster the long-term protection of groundwater resources worldwide.

This is part of our social responsibility, right?

As Stephanie J. Bird says in her paper Socially Responsible Science Is More than “Good Science

“[…] as members of society, scientists have a responsibility to participate in discussions and decisions regarding the appropriate use of science in addressing societal issues and concerns, and to bring their specialized knowledge and expertise to activities and discussions that promote the education of students and fellow citizens, thereby enhancing and facilitating informed decision making and democracy.”

Therefore, as groundwater scientists, part of our responsibility is to commit to share the results of our investigations outside the academic sphere and to find the most appropriate way to engage with civil society. This can be done in several ways, like through public speaking, social networks, media release and active involvement with local communities relying upon the water resources we are studying.

Academics-ivory-tower (Frits Ahlefeldt)

But, is this enough? Is outreach sufficient to ensure that we effectively bridge the famous gap between science and society?

 

What if we also engage to live more sustainably and to help driving the changes we aim to inspire with our research?

As scientists, every time we write about our work and research results, we almost always find ourselves discussing water distribution on Earth, the global water crisis and the need for sustainable water resources management. We often tell people the importance of saving water, recycling and reducing pollution, and certainly we aim to use the best available scientific tools for providing this information. But then, in our minds, it should also lead us to question whether we, the scientists, actually live sustainably and act responsibly.

Are we really acting to ensure safe water resources, for future generations? We know our food and good consumptions depend on energy and water, but still the global water demand is rising. Still, is there something we can do to diminish our water and ecological footprint? Is there something that we can do to bring the scientific knowledge in our everyday life? What if we would better engage to inspire people, our friends and local communities, and become true advocates of (ground)water protection and management?

We’ve decided to take action on these issues through Responsible Water Scientist, a project launched almost a year ago my myself and my friend and colleague Raquel Sousa. Responsible Water Scientist, is a space where we aim to encourage a broader discussion on the little changes in the daily routine that can make scientists real advocates of groundwater conservation for a more sustainable world. These changes can involve our dietary choices, shopping attitudes and consumption patterns, but are all closely related to our water footprint and the future of global water resources.

Bulk shopping saves plastic packaging and reduces our carbon and water footprint.

Drinking tap water (if safe and available) and bringing our own water bottle will significantly reduce the amount of plastic bottles produced per year.

 

Shopping bulk, reducing our meat consumption or engaging for a zero waste lifestyle may seem really challenging at first, but the effort is really worth it, indeed, every drop matters! Don’t you agree?

An alternate career path for Groundwater Science-Engineering PhDs

An alternate career path for Groundwater Science-Engineering PhDs

Post by Jim Roy, Research Scientist at Environment and Climate Change Canada.

_______________________________________________

A recent editorial in Nature highlighted the relative scarcity of academic positions available to graduating PhD students (Many junior scientists need to take a hard look at their job prospects; 25 October, 2017). It notes that “it has been evident for years that international science is training many more PhD students than the academic system can support”. Firm figures aren’t available, but the article suggests maybe < 5 % will land a full-time academic job. That number may be somewhat higher for Groundwater-related disciplines, but the point remains that many should “make plans for a life outside academic science.”

However, it’s not all doom and gloom; indeed the article goes on to state that “it is good for PhD students and postdocs to pursue careers outside academia. Many will find similar challenges and rewards in industry.” There are a lot of options for Groundwater PhDs in industry and the plethora of supporting consulting firms: in mining, oil and gas, tunnel and dam engineering, municipal water supply, and contaminated site remediation, to list a few. However, there is an additional career path to consider, especially if you want to continue doing research – the government scientist, like me.

According to Wikipedea: A government scientist is a “scientist employed by a country’s government, either in a research-driven job (for example J. Robert Oppenheimer on the Manhattan Project), or for another role that requires scientific training and methods.” I’ll be focusing on those that do research (encompassing science and engineering), at least for much of their work.  And in this blog, I’ll be comparing their job duties and conditions to that of the professor, the research job with which the majority of students and post-docs are most familiar and traditionally aiming for.  It’s what I thought I would be too, coming out of grad school. Now it’s been 10 years since I took up my position as a Research Scientist focusing on groundwater contamination/quality with Environment Canada (now Environment and Climate Change Canada) – enough time to have experienced the ups and downs of the Canadian economy and the changing of the governing party, with repercussions of both for federal science priorities and budgets. The discussion below is based largely on my own experience, with insight gleaned from talking with colleagues in other government agenciesa over the years. It’s also highly generalized; the exact situations will vary by country, agency, and even by individual scientist, and may change over time. But hopefully it’s good enough for a light-hearted introduction to this alternate career area.

So here goes – my Top 10 list of how a government scientist job is different than academia:

  1. Freedom

                All scientists want to do work that is meaningful, but not all scientists get to choose on what topic that work will focus. In general, government scientists undertake research on issues of government priority that will advise on federal policy, regulations, and management activities, or that will provide service to important national industries or the public. So their work should have a meaningful impact on their country, if not more broadly; they just don’t get to decide on the priority topics (with exceptions for certain agencies or programs). However, often these priority topics are general enough that there is some range of projects that can fit within them, giving the scientist some flexibility on their research focus. Also, by advising their management and government representatives of important topics, government scientists may influence the direction of government priorities. Also, a government scientist may be afforded some leeway to work on additional topics outside these priority areas with a small fraction of their time. Government research usually targets short- to intermediate-term achievements, as fits the common government election cycle. However, some priority topics may last for decades – see North American Great Lakes eutrophication and algal blooms – waxing and waning in importance with the severity of the problem (costs!) in relation to the other pressures on the government (the economy!). For those who choose this career path – beware, though, when government priorities change, your research area may have to change too.

                For academics, their options are typically much broader, encompassing everything between applied research with immediate implications to research so basic that nobody can predict what may eventually come of it. The caveat to this is that an academic’s research topic often has to be deemed important enough and applied enough for “someone” to fund it. Industry funding is usually quite applied. But even government funding agencies, which are usually the primary support for more basic academic research, are increasingly imposing greater direction over the acceptable topics of proposed research. So perhaps this extra freedom isn’t so vast in practice.

  1. Trading places?

                Many government scientists are appointed to one or more adjunct professor positions at universities where their academic collaborators reside. These could be at nearby universities or those across the globe, and these locations may change over a career. It isn’t a paid position, but allows for closer research ties, including the (co-)supervision of undergraduate and graduate students, which benefits both the university and the government agency. Such positions may also afford access to laboratory space on campus or to additional research funding (held at the university, but directed by the adjunct professor).

                I haven’t heard of a case of the opposite arrangement – adjunct government scientist – but it might exist. Academics may pop in and be given some office space and support during a sabbatical while collaborating with a government scientist, but they’re really just temporary squatters.  If anyone out there knows of such a situation, feel free to post below.

  1. No teaching ( 🙂 or  🙁 )

                An obvious difference, this can be viewed as good or bad news depending on how much you like it.  I enjoyed teaching while I was a grad student. Many scientists give guest lectures or even short-courses at local universities. I taught an entire hydrogeology course for a university colleague during his sabbatical – so this can be an option for some in government who have an interest. Not having required teaching does provide greater flexibility in scheduling your work (especially field trips) and leaves more time for research and/or other important activities, like playing hockey or “family life”.

  1. Professors have grad students; government scientists have technicians

                The model for academic research is based on students and post-docs (a team of them often) carrying out the primary duties of research under the supervision of their professor. Certainly there are exceptions where the professor carries out their own study, but generally they lack the time for this. However, professors may have technicians too. It’s common for some to hire current or past students as technicians for a few years after they graduate, while (senior) professors may have dedicated technicians.

                In contrast, the model for government scientists is to have one or more dedicated and highly-experienced technicians available to assist in their research. Separate analytical laboratory or field teams may also be available. Although, with tightening budgets this technical support seems to be dwindling. It’s also fairly common for post-doctoral fellows to be hired by government agencies to work with their scientists – I’ve worked closely with 2 post-docs over my 10 years at Environment and Climate Change Canada. And what’s more, through adjunct professor positions or just collaborations, government scientists may also work with and (co-)supervise students from a partner university, just not to the same extent as for the academics.

                Thus, there can be a fair bit of overlap between these two models, especially when collaborations extend between academics and government researchers; and this integration, I think, makes for better science all around.

  1. Both are sought out by regulators and policy-makers

                Government scientists might have the inside track to the ear of policy-makers, but advice from academics is often gathered via workshops and contracts for reviews and reports as well.  Sadly, in large departments especially, some bureaucrats may not realize they have internal expertise in an area like hydrogeology. Which leads us to the next point…

  1. Governments typically do a poorer job of selling/showcasing their scientists

                Academics have much more freedom to showcase themselves and their work to the public, the science community, and business/industry. This can be through personalized research web pages, starting a blog (like this one!), and greater freedom to speak to the media (depending on the presiding-government’s rules for their scientists).  They also tend to attend more scientific conferences, where they and their students can advertise their scientific wares to a range of audiences.

  1. No consulting on the side

                Not all professors consult, but many do, which can provide a boost in income and lead to funding or in-kind support opportunities for their research or to job opportunities for their students. I haven’t heard of any government agencies that allow their scientists to consult as a side profession. In part, they want all your time devoted to your job working for them; but it also runs into “conflict-of-interest” concerns.  Now that doesn’t mean you can’t have a side-job (e.g., selling pottery, repairing dishwashers, stand-up comedy, teaching Yoga), but it can’t relate to your science profession.

  1. Border-crossing restrictions

                Working on national (or state/provincial) priority research commonly means government scientists work predominantly on sites in their own country (region), unless inter-jurisdictional agreements are made to combine or share research expertise. In contrast, academics are able and encouraged to work at international sites, which can expand the range of research topics and potentially funding sources available to them.

  1. Less competition for funding (except when the coffers are bare)

                Much of my funding is internal, requiring much shorter (i.e., less onerous) proposals than is typical for my academic colleagues seeking funding through centralized national funding agencies (e.g., NSERC in Canada) or from industry partners. My proposals may still go through a competitive process, though, sometimes with external reviews.  How substantive this internal funding is compared to academic funding will depend on the agency, how science is viewed by the current government, the state of the economy, and the importance of the topic. When internal research budgets are tight, there may not be sufficient funding to go around, especially for those not working directly on key priorities. Of note, some government agencies allow their scientists who have adjunct status at a university to apply for the same set of grants as academics. Whether such proposals are frowned upon or judged differently by funding agencies is up for debate.

  1. Joy in their work

                Frustrations with too-much time devoted to administrative tasks and seeking funding are prevalent in both government and academic research areas. But still, the opportunity to do research on interesting, challenging, and important topics at the edge of our current scientific understanding brings enjoyment / fulfillment to both government scientists and academics. We all feel that slight quickening of the pulse when “the data is in” and we learn if the expected outcomes were realized or (better yet) something different (new!) might be going on.  It’s why we do what we do. In hydrogeology, there remains much to explore, especially at the inter-disciplinary mixing zones around the edges of our specialty. And we’ll need new concepts, new methods, and new connections to move our understanding forward. Scientists from academia and government and industry and other groups can all contribute to this quest. For graduating PhDs, hopefully this leaves you with multiple career path options for joining in the fun.

a In Canada, besides Environment and Climate Change Canada there are also PhD-holders doing groundwater-related research in Natural Resources Canada, Agriculture and Agri-Food Canada, and the National Research Council. In the U.S., much great groundwater research is carried out by the U.S. Geological Survey, with research also carried out by other federal and state agencies. Many other countries have similar geological or environmental departments or agencies with PhDs doing some or much research.  You can look these up on the web, though often government scientist pages aren’t nearly as good as those for academia.

Hydraulic fracturing close to groundwater wells

Hydraulic fracturing close to groundwater wells

Post by Scott Jasechko, Assistant Professor of Water Resources with the Bren School of Environmental Science & Management, at the University of California, Santa Barbara, and by Debra Perrone, non-resident Fellow at Water in the West and an Assistant Professor, also at the University of California, Santa Barbara, in the United States.

_______________________________________________

In December, 2016, the Environmental Protection Agency finalized a report [Ref. 1] on hydraulic fracturing and drinking water resources that, among other conclusions, states:

(a) Quote from [Ref. 1]: “scientific evidence that hydraulic fracturing activities can impact drinking water resources under some circumstances”

(b) Quote from [Ref. 1]: “When hydraulically fractured oil and gas production wells are located near or within drinking water resources, there is a greater potential for activities in the hydraulic fracturing water cycle to impact those resources.”

Tens-of-millions of Americans rely on groundwater stored in aquifers for drinking water. Because it is possible that hydraulic fracturing activities can impact water resources (i.e., quote (a) above), and because groundwaters located close to hydraulic fracturing activities are more likely to be impacted than those farther away should a contamination event occur (i.e., quote (b) above), it is important to assess how many domestic groundwater wells are located close to hydraulically fractured wells.

In a recent study [Ref. 2], we assessed how close domestic groundwater wells are to hydraulically fractured wells, and to oil and gas wells (some hydraulically fractured, some not). Due to consistencies limitations in both oil and gas and groundwater well datasets, we limited our analysis to groundwater wells constructed between 2000-2014, hydraulically fractured wells likely stimulated during the year 2014, and oil and gas wells producing in 2014.

Our study has two main findings.

First, we found that most (>50 %) recorded domestic groundwater wells constructed between 2000 and 2014 exist within 2 km of at least one hydraulically fractured well in 11 US counties (Fig. 1). Further, about half of all recorded hydraulically fractured wells that were stimulated during 2014 are located within 2-3 km of at least one domestic groundwater well. We suggest these regions where groundwater wells are frequently located near hydraulically fractured wells might be suitable areas to focus limited resources for further water quality monitoring.

Figure 1. The percentage of domestic groundwater wells that were constructed between 2000 and 2014 that have a recorded location that lies within a 2 km radius of the recorded location of at least one hydraulically fractured well that was stimulated during the year 2014.

Second, we assessed the proximity of oil and gas wells being produced in 2014 – some hydraulically fractured but others not – and groundwater wells. We found that many domestic groundwater wells are located nearby (<1-2 km) at least one oil and gas well, and, that actively-producing oil and gas wells are frequently located nearby at least one domestic groundwater well (Figure 2). Many of the potential contamination mechanisms associated with the construction, stimulation and use of hydraulically fractured wells are also associated with conventional oil and gas wells, including potential for spills on the land surface and well integrity failures [Ref. 3]. Therefore, assessing potential water quality impacts resulting from activities associated with oil and gas production derived from both hydraulically fractured wells and from conventional oil and gas wells is important.

Figure 2. The upper panel shows the distance between recorded oil and gas wells producing in 2014, and recorded domestic groundwater wells constructed between 2000 and 2014. The lower panel shows the distance between recorded domestic groundwater wells constructed between 2000 and 2014 and the nearest recorded oil and gas wells producing in 2014 (see Ref. [2] and references therein for data sources).

We conclude that (i) publicly-available groundwater well construction data are critical for managing groundwater resources and completing water quality risk assessments (see Ref. 4 for data quality information), and emphasize that not all states currently provide access to digitized groundwater well construction records (e.g., Figure 2), (ii) hotspots exist where activities related to oil and gas production occur nearby domestic groundwater wells, and these regions may be targeted for further groundwater quality monitoring, and (iii) assessing how frequently activities in the hydraulic fracturing water cycle impact groundwater quality may be vital to securing high quality water pumped from many domestic water wells where oil and gas production is common.

Bedrock: A hydrogeologist’s devotional

Bedrock: A hydrogeologist’s devotional

Post by Kevin Befus, Assistant Professor at the College of Engineering and Applied Science at the University of Wyoming, in the United States.

_______________________________________________

I want to share a book with you that has encouraged me through initial academic mires (I was only in graduate school for 7 years…) and inspired me to expand my perception and appreciation of the natural world.

The book is Bedrock: Writers on the Wonders of Geology [Savoy et al., 2006]. It is a carefully curated collection of snippets and excerpts from international literary sources describing geologic processes and outcomes. Most of the writings come from the 20th century with several exceptions extending not quite as far back as the Pleistocene. Each chapter, or collection of writings, is oriented around a theme in the earth sciences, one of which is “Rivers to the Sea”…the creative views of hydrologic, mainly riverine, processes chapter. While the excerpts are the main event in each chapter, a quick introduction to each selection is given within the broader geologic context along with some reasoning in why each was chosen.

Bedrock is not a book about hydrogeology, and it really doesn’t directly talk about water underground. BUT, Earth is explored in the excerpts, and developing connections between groundwater and other geologic processes is our job, not the literary masters who “contributed” tidbits to the book. As you should have expected, John McPhee shows up a number of times, but not too much. Many of the early geologists (e.g., G.K. Gilbert, James Hutton, and John Wesley Powell) and environmentalists (e.g., Rachel Carson and John Muir) also share their reflections of geologic forces on nature.

As someone who reads blogs about groundwater, remember to extend the literary reflections to include how the topics interact with groundwater systems. For example, the cover image evokes excitement (or consternation) from a groundwater hydrologist, as it shows the coastline of Nullarbor Plain in southern Australia, home to the “world’s largest limestone karst area” (http://www.australiangeographic.com.au/travel/destinations/2016/04/hidden-nullarbor).

My suggestion for reading this book is to take it slow: one excerpt in the morning to kick-start the day, remembering why it is you do what you do. Be inspired, awed, and reminded of how geological processes have shaped our world over billions of years. Or, read an entry when the day has taken a turn to the slow or chaotic. Like any good devotional, Bedrock has great re-readability and also points you towards the original documents for more in-depth explorations of literary (hydro)geology.

Happy reading!
