THE Supreme Court has initiated suo motu proceedings regarding the excessive and unregulated extraction of groundwater by bottling companies. To be fair, the court is driven by a genuine desire to conserve our aquifers but because judges are not perceived as well suited to handling questions of policy, the focus thus far has been on short-term fixes only. A proper resolution of the issue requires us to address the structural problem first. Groundwater is a scarce resource and every time a state is confronted with conditions of scarcity, it must undertake the process of resource allocation. This effectively means that when there are multiple people with competing claims over the same resources, society must devise a mechanism to determine how those limited resources are to be distributed amongst the claimants and which claim is to be prioritised over the other. Property law serves that function. It helps allocate limited resources and then provides a framework through which those resources can be transferred between people once the initial allocation has taken place. Our structural difficulties with the regulation of groundwater extraction start here because we have never managed to do the initial allocation of rights in groundwater correctly.

Nitrate from land use activities can leach out of the root zone of the crop into the deeper part of the unsaturated zone and ultimately contaminate the underlying groundwater resources. Nitrate travels with the groundwater and then discharges into surface water causing eutrophication of surface water bodies. To understand the source, fate, and future nitrogen loads to ground and surface water bodies, detailed knowledge of the groundwater flow dynamics is essential.
Well-known examples include those in Bath, Buxton and Harrogate. Bathing in these waters was popular amongst fashionable society in the seventeenth and eighteenth centuries, as it was considered beneficial to health. The practice continued into the nineteenth century but declined after that in the UK. Thermal springs are a natural phenomenon which occur where hot water from great depths in the Earth rises to the surface.
In the UK, groundwater normally has a temperature around oC and reflects the average annual air temperature. Shallow springs therefore have a similar temperature.

Water Dating Course Drinking Water Security Water age dating is a simple way to test the security of groundwater aquifers, by establishing how long the water has been underground, i. Deeper groundwater sources can overcome the most common problems that arise from microbiological contamination of surface waters, shallow groundwaters and spring water.
Not directly affected by surface or climate influences Abstracted from a bore head that provides satisfactory sanitary protection Age dating yields an average age of the water as most groundwaters are mixtures of water with different ages. The important question is: What is the fraction of the water with age less than one year?

Carbon is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer. C dating is only applicable to organic and some inorganic materials not applicable to metals. Gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry are the three principal radiocarbon dating methods. Radiocarbon measurements are reported as Conventional Radiocarbon Age. What is Radiocarbon Dating? Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms.
The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century. Archaeology and other human sciences use radiocarbon dating to prove or disprove theories. Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.

Englewood Cliffs, New Jersey, By contrast, the volume of surface water in lakes, rivers, reservoirs and swamps could be contained in a depth of about one quarter of a metre. It is extremely difficult to estimate the volume of groundwater on the entire planet. However, all the estimates imply that if we do not include the water frozen in ice caps, glaciers and permanent snow, groundwater makes up almost the entire volume of the earth’s usable fresh water.

March A rocker bogie In motion – incorrectly shows chassis staying level; the chassis actually maintains the average of the two rockers Rocker bogie on Curiosity The rocker-bogie system is the suspension arrangement used in the Mars rovers mechanical robot introduced for the Mars Pathfinder and also used on the Mars Exploration Rover MER and Mars Science Laboratory MSL missions.
These rockers are connected to each other and the vehicle chassis through a differential. Relative to the chassis, when one rocker goes up, the other goes down. The chassis maintains the average pitch angle of both rockers. One end of a rocker is fitted with a drive wheel and the other end is pivoted to a bogie. Bogies were commonly used as load wheels in the tracks of army tanks as idlers distributing the load over the terrain. Bogies were also quite commonly used on the trailers of semi-trailer trucks.
Both applications now prefer trailing arm suspensions.

How Old is our Groundwater? Groundwater Ages Groundwater can either be very young, representing recent recharge to the subsurface, or it can exist as very old water that has been interacting with the rock and sediments that host it. For example, a shallow flow system would constitute recharge in a small upland area followed by discharge to an immediately adjacent low-lying area.
The distance of groundwater travel may be on the order of ‘s of metres. In contrast, groundwater flow in deeper regional flow systems can travel several ‘s to 1, ‘s of kilometres. A classic example of a deep regional flow system in Alberta is the general flow of groundwater from the recharge area in the western part of the province near the Rocky Mountain cordilleran and foothills region eastward across the plains areas towards the province of Saskatchewan see chart – right.
UK Thermal and Mineral Springs. There are many small thermal (hot) and mineral springs in the UK. Well-known examples include those in Bath, Buxton and Harrogate. Bathing in these waters was popular amongst fashionable society in the seventeenth and eighteenth .
Water Dating Course Groundwater Resources Age of groundwater or time of recharge, combined with knowledge of the hydrological setting, can provide valuable information for planning the sustainable management of groundwater resources. Once water has entered the groundwater system the tracers become isolated from input sources and the time of recharge can be reconstructed from known historic concentrations.
Water dating has been hailed internationally as a breakthrough in managing aquifer systems and in detecting early signs of deteriorating water quality. The ability to accurately age-date young groundwater adds considerable value to groundwater resource or quality surveys because: Recent hydrological studies undertaken by the GNS Science team using age dating methods include: Wairarapa Valley Groundwater — residence time, flow patterns and hydrochemistry trends.

In the southern half of Australia, recent droughts and predictions of a drier future under a number of climate change scenarios have led to the search for innovative strategies to identify more secure water supplies for regional communities and industries, while also delivering environmental benefits to threatened river systems. These issues are of particular concern in the Murray-Darling Basin, where the recent Millennium Drought late ‘s – adversely affected many communities, industries and the environment.
Beginning in , the BHMAR has become the largest hydrogeological investigation project undertaken by the Australian Government in the past 30 years, and has delivered outcomes that could herald a new approach to water security in Australia by using aquifers during drought periods to reduce our dependence on surface water. Investigations to secure Broken Hill’s water supply have identified a priority site Jimargil that could provide enhanced drought security for Broken Hill.
Provides advice and information to the Australian, State and Territory Governments, natural resource authorities and the community on a variety of groundwater resource issues.
A small-neck bottle will generally seal better than large-neck bottle but both are fine. We no longer recommend adding a small amount of NaOH to the sample. This was a necessary step in the process of DIC precipitation but not for the gas strip method used by our lab. Please let us know if your samples contain salt or have been in the proximity of any location using labeled 14C artificial 14C. We cannot accept seawater samples that have been treated with mercuric chloride HgCl2 or sodium azide NaN3 because we do not have the disposal capabilities for these toxic substances.
Beta Analytic is offering Oxygen and Deuterium stable isotope measurements for water samples at no additional cost for samples submitted for radiocarbon dating. These analyses can also be ordered on a standalone basis without radiocarbon dating. How to Collect Groundwater Samples 1. Collect water at the wellhead. Depending on the depth of the well, this may be several minutes or longer.
At the time that Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be million years old. By , it was found to be 1. In , science firmly established that the earth was 3. Finally in , it was discovered that the earth is “really” 4. In these early studies the order of sedimentary rocks and structures were used to date geologic time periods and events in a relative way.
Hydrologic sciences: Hydrologic sciences, the fields of study concerned with the waters of Earth. Included are the sciences of hydrology, oceanography, limnology, and glaciology. In its widest sense, hydrology encompasses the study of the occurrence, movement, and physical and chemical characteristics of water in all.
It is the first confirmation of aquifer contamination associated with coal seam gas activity in Australia – a blow to an industry pushing state and federal governments for permission to expand. Grazier and protester Ted Borowski lies in a dry creek bed ready to disrupt drilling operations in the Pilliga forest by locking himself to a truck. Two days later, Deputy Premier Andrew Stoner signed a memorandum of understanding with Santos to speed up the project, in the Pilliga forest near Narrabri, guaranteeing a decision on its future by January 23 next year.
Related Articles Santos coal seam gas project contaminating aquifer in use after two years The EPA says it launched an investigation after routine testing in March last year by Santos of groundwater around the project – which remains in the test well stage – detected ”elevated levels of total dissolved solids and slightly elevated levels of other elements”. The investigation concluded there was no evidence contractors engaged by the previous owner of the project, Eastern Star Gas, followed strict rules when building a pond to hold waste water and brine produced when gas is extracted.
The investigation concluded the pond liner was of ”poor quality, which resulted in the integrity of the liner being questionable”. Advertisement On Friday, EPA chief environmental regulator Mark Gifford confirmed the contamination was caused by water leaking from the pond and that lead, aluminium, arsenic, barium, boron, nickel and uranium had been detected in an aquifer at levels ”elevated when compared to livestock, irrigation and health guidelines”.
Mr Gifford also confirmed uranium levels were detected in an aquifer at micrograms per litre – about 20 times the safe drinking water guideline of 17 micrograms per litre. Wilderness Society national director Lyndon Schneiders called on federal Environment Minister Greg Hunt to stop all CSG operations immediately, ”until there is a full independent and transparent investigation into the industry”.

Down to Earth Surface conditions of the planets Venus and Mars are compared with those of Earth, and scenes of Earth’s living landscapes lead into a discussion of how unique Earth truly is. Major topics addressed in the series, including plate tectonics, natural resources, seismology, and erosion, are introduced in this program. However, this notion changed dramatically over time, especially after the invention of the telescope.
This program traces the development of astronomical theory with discussions of the discoveries of Copernicus, Galileo, Kepler, and Newton. Unique characteristics of Earth are also discussed. This program introduces the topic of geophysics, exploring methods of studying what lies beneath Earth’s surface. Geophysicists use seismic wave studies, variations in temperature, magnetic fields, gravity, and computer simulations to create models of deep structures.
The Sea Floor The mysteries of the ocean floor lie hidden under enormous pressure and total darkness. This program looks at the research submersibles and indirect methods used to study the bottom of the sea, providing a glimpse of volcanic activity, formations such as the continental shelf and mid-ocean ridges, and life forms that thrive at extreme depths. The Birth of a Theory In the s, earth scientists developed the theory of plate tectonics.
This program traces the development of plate tectonics, beginning with the contributions and methods of geologist Alfred Wegener. Sea-floor spreading, continental drift, paleomagnetism, and the primordial supercontinent Pangaea are some of the topics covered. The program covers convergent boundaries, subduction, hotspots, and the debate over what drives plate motion.
Mountain Building This program erodes the myth of the mountain as a solid, permanent structure.
