We have just received our subscription of the Water Well Journal for April 2017 from the National Groundwater Association (NGWA).
This issue includes articles on well design, wells’ life-cycle, nitrates and groundwater, water treatment, preventing muscle injuries through ergonomic processes, managing cash flow, engineering of water systems and other relevant information.
Those of you who are interested in viewing this journal can email me or visit me at my desk.
Mark your calendar guys for Wednesday April 12th 2017 at 3.00 PM for the above mentioned Webinar on the new 6470 LC/TQ from Agilent Technologies which would be used for the detection of several pharmaceuticals and pesticides in surface waters.
For decades now, the most common detected environmental contaminants in water are pesticides and pharmaceuticals. Because these types of organic compounds are mostly polar, liquid chromatography mass spectrometry has been the methodology of choice for their analysis. Usually a sample preparation step such as solid-phase extraction has been necessary for the detection of these contaminants at low ng/L. However, with the advent of newer and more sensitive instruments, this step can be omitted while still achieving these low detection limits. In this session we’ll show some examples of compounds identified in surface waters at these concentration levels and how to optimize the best conditions and parameters for their optimal detection.
In this session, we’ll focus on the use of the new 6470 LC/TQ instrument from Agilent Technologies for the sub ng/L level detection of several pharmaceuticals and pesticides in surface waters. Examples of optimization of several source parameters and voltages will be shown for the ionization of specific analytes, including hormones. Also, quantitation using larger volume injections (100uL) will be shown for the direct analysis of contaminated water samples.
What you will learn:
How to optimize intrinsic source parameters in MassHunter software
Large volume injection (100uL) considerations
Learn to choose best product ions with Optimizer software
Method development techniques
A list of the most commonly detected pharmaceuticals in surface and drinking waters

In celebration of World Water Day 2017, John Wiley and Sons has made available wastewater related articles due to this year’s theme being “wastewater”.
As such persons can view articles online and download PDFs, from relevant journals such as Water Resources Research, Journal of the American Water Resources Association, as well as, Water and Environment Journal, from March 22 – 28 2017.
I do hope you find some interesting articles to celebrate World Water Day 2017. Enjoy 🙂
Freshwater ecosystems constitute a small fraction of our planet but play a disproportionately large and critical role in the global carbon cycle.
As human activities continue to pump carbon into the atmosphere, the backbone of our understanding of the resulting warming is our knowledge of where that carbon is going: into the atmosphere, into the land, and into bodies of water. When it comes to accounting for the carbon absorbed and emitted by water, the role of inland freshwater may appear quite small compared to the vastness of Earth’s oceans. After all, inland lakes, rivers, streams, reservoirs, wetlands, and estuaries cover less than 4% of Earth’s surface [Downing, 2010; Verpoorter et al., 2014].But recent research shows that the roughly 200 million bodies of inland water play a much larger role in the global carbon cycle than their small footprint suggests. Inland streams and rivers move vast amounts of carbon from the land to the ocean, acting as carbon’s busy transit system.
They also play a disproportionately large role in the global carbon cycle through their high rates of carbon respiration and sequestration [Cole et al., 2007; Tranvik et al., 2009].According to recent estimates, the amount of carbon that inland waters emit is comparable to the net amount of carbon absorbed by living organisms on Earth’s land surface and in its oceans. Moreover, bodies of freshwater bury more carbon in sediments each year than the vast ocean floor [Battin et al., 2009; Aufdenkampe et al., 2011].
Nevertheless, there is great uncertainty in these figures, and scant data exist on continental and global scales. The changing climate is putting freshwater ecosystems at great risk: They are warming at an alarming rate, outpacing warming of the atmosphere and oceans. It’s crucial that scientists dedicate more resources to understanding the global impact of the freshwater continuum on the carbon cycle.

If increasingly globalized societies are to make better land management decisions, the geosciences must globally evaluate how humans are reshaping Earth’s surface
Since geologic time began, Earth’s surface has been evolving through natural processes of tectonic uplift, volcanism, erosion, and the movement of sediment. Now a new force of global change is altering Earth’s surface and morphology in unprecedented ways: humanity.
Human activities are leaving their fingerprints across Earth (Figure 1), driven by increasing populations, technological capacities, and societal demands [e.g., Ellis, 2015; Brown et al., 2017; Waters et al., 2016]. We have alteredflood patterns, created barriers to runoff and erosion, funneled sedimentation into specific areas, flattened mountains, piled hills, dredged land from the sea, and even triggered seismic activity [Tarolli and Sofia, 2016]. These and otherchanges can pose broad threats to the sustainability of human societies and environments.
If increasingly globalized societies are to make better land management decisions, the geosciences must globally evaluate how humans are reshaping Earth’s surface. A comprehensive mapping of human topographic signatures on a planet-wide scale is required if we are to understand, model, and forecast the geological hazards of the future.
Understanding and addressing the causes and consequences of anthropogenic landform modifications are a worldwide challenge. But this challenge also poses an opportunity to better manage environmental resources and protect environmental values [DeFrieset al., 2012].
