The Yarragadee Aquifer is a significant freshwater aquifer located in the south west of Western Australia and predominantly beneath the Swan Coastal Plain west of the Darling Scarp . It has a north south range from about Geraldton, Western Australia Geraldton to the south coast, but with a split in the formation south of Perth, Western Australia Perth . The southern part is known as the South West Yarragadee Aquifer . The aquifer is quite deep, situated hundreds of metres below ground level and with a thickness ranging up to about two kilometres. In the Perth area, the Yarragadee Aquifer is located beneath the Leederville Aquifer , which itself is located beneath two superficial aquifers known as the Gnangara Mound and Jandakot Mound . These aquifers are separated by impervious layers with no groundwater called aquitard s. The Yarragadee Aquifer stores about 1000 cubic kilometres of water, compared to about 20 cubic kilometres in the Gnangara Mound. As such it is seen as a potential source of water, and the Water Corporation of Western Australia currently extracts about 45 Litre gigalitres per year from the aquifer. One cubic kilometre is equivalent to 1000 GL. Ultimately the Yaragadee Aquifer is replenished by rainfall. This recharging is usually where there are outcroppings near other aquifers like the Leederville Aquifer. There are also outcrops near the surface in the vicinity of the Blackwood River . Current models estimate this recharge at about 280 to 340 GL per year. This groundwater can remain in the aquifer for many years in some areas the age of the groundwater is over 30,000 years. Geologically, the aquifer is part of what is known as the Yarragadee Formation, which ... 4415 5769 1319 1270 title South West Yarragadee Aquifer Water Source Investigation Water Corporation ... files SW Yarragadee SWAMS.pdf title South West Yarragadee Aquifer South West Aquifer Modelling ... 204.pdf title Yarragadee Aquifer Geology report, 115kb pdf accessdate 2007 04 10 archiveurl http ... more details

Unreferenced date July 2009 Orphan date November 2006 The Sankoty aquifer is an aquifer in the U.S. state of Illinois that provides groundwater to a number of communities in northwestern and central Illinois. It is an unconsolidated deposit lying in a bedrock valley formerly occupied by the ancestral Mississippi River . Type locality The sand which forms the Sankoty aquifer was named after a railroad siding near Peoria, Illinois in 1946 by Leland Horberg. The legal description given by Horberg in identifying the type locality geology type locality for the Sankoty sand is T9N, R8E, Section 15 Peoria County, Illinois . Lithology and stratigraphy The Sankoty sand is an unconsolidated deposit within a bedrock valley formerly occupied by the ancestral Mississippi River. It is classified as a member of the Banner Formation and occupies the same stratigraphic position as the Mahomet sand. The Sankoty sand has distinctive characteristics that are readily recognized in sample cuttings. In its most typical aspect, the Sankoty is composed of 70 to 90 percent quartz grains of which 25 percent or more are pink, rounded, and polished. The texture is usually medium grained but varies from silty fine sand to coarse gravelly sand. Groundwater occurrence The Sankoty sand is one of the most extensive aquifers in the state. It frequently is convert 100 ft m thick and is typically found below elevations of 520 to 530 feet above sea level. It has been used as a water source in the Peoria area since at least 1892. By 1909, it was observed that groundwater levels at the North Field in Peoria fluctuated with the river stage in the Illinois River . The Sankoty aquifer extends beyond the width of the Illinois River valley and occurs beneath the uplands. In these locations, it is frequently confined by clayey deposits of glacial till which may include other sands . Consequently, the groundwater may occur under confined Artesian aquifer artesian conditions. References Groundwater in the Peoria Region ... more details

coord 51.491 3.548 display title region GB scale 10000 Schwyll Aquifer pronounced Shwill was historically known as the Great Spring of Glamorgan . Until recently, Welsh Water used the resurgence at the Schwyll Spring near Ewenny as the main source of water for the Bridgend area. It now functions as a backup supply and as such has a number of associated source protection zone s policed by the Environment Agency . The outflow of the Spring hydrosphere spring is far larger than any other freshwater spring in Wales and greater than that from Wookey Hole or Cheddar Gorge risings. The aquifer consists of an underground waterway in the Carboniferous Limestone of South Wales . Due to the delay between local heavy rain and discoloration of the water at the spring, it is believed that the water originates from as far as 20 miles away. This would locate the main source in the limestone of the southern edge of the Brecon Beacons . The lack of an accessible cave cavern at the rising hinders exploration of the cave system. The only known point of access so far is at the pumping shaft of the extraction plant at Schwyll. The system was explored by cave divers in 1998 to a distance of 440 metres from the shaft. At 400 metres, a large cavern was discovered containing some bones which were identified as a species of horse. The bones were submitted for dating.

Orphan date February 2009 Aquifer storage and recovery ASR is the re injection of potable water back into an aquifer for later recovery and use. ASR has been done for municipal, industry and agriculture use. The first agriculture ASR wells were put into service in Oregon in the autumn of 2006 and have injected well over a convert 3000 acre.ft m3 of water during the winter and spring flood flow times using artificial recharge AR of flood water as their water source. This shallow recharged water is then recovered as potable water and injected into the deep basalt aquifer. During the injection process electrical energy can be generated by the head pressure of the water flowing back into the aquifer. This stored water is recovered during late summer and early autumn for irrigation needs. Both of these wells use a down hole control valve built by 3R Valve of Echo, Oregon. ASR can also be used to re inject water used by HVAC systems to maintain the ground water levels and store the thermal differances from summer time cooling for winter time heating. Industary can also capture cold winter waters and store it for summer time use and avoid the need for cooling water in the summer for indrustral processes. This may also free up short supplies of summer time water for other benafitical uses. This reinjection process may also avoid the cost of surface disposal and avoid the increased thermal load to the rivers and streams during the summer air conditioning season. ref cite web url http www.3rvalve.com title Aquifer Storage and Recovery ASR coauthors Kent Madison year 2008 publisher 3R Valve accessdate 2008 12 26 ref See also Groundwater recharge References references External link http www.agwt.org AquiferManagement&ASR.htm American Ground Water Trust ASR Info Category Aquifers Category Building biology Category Building engineering Category Water supply Category Water and the environment es Recarga artificial de acu feros ar ... more details
