Water Water An aquifer is an underground layer of water-bearing permeable rock, or unconsolidated materials ( gravel, sand, silt, or clay) from which groundwater can be usefully extracted using a water well. A common misconception is that groundwater exists in underground rivers (e.g. caves where water flows freely underground). This is only true in eroded limestone areas known as Karst topography which make up only a small percentage of Earth's area. More usual is that the pore spaces of rocks in the subsurface are simply saturated with water — like a kitchen sponge, which can be pumped out and used for agricultural, industrial or municipal uses. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. ...more on Wikipedia about "Aquifer"
An Aquifer test is conducted to evaluate an aquifer by "stimulating" the aquifer through constant pumping, and observing the aquifer's "response" ( drawdown) in observation wells. Aquifer testing is a common tool that hydrogeologists use to characterize a system of aquifers, aquitards and flow system boundaries. ...more on Wikipedia about "Aquifer test"
Archimedes' screw, or the Archimedean screw, is a simple machine historically used for transferring water from a low-lying body of water into irrigation ditches. It is one of several inventions and discoveries reputed to have been made by Archimedes, though writings about the Hanging Gardens of Babylon hint that a similar device was used by the Mesopotamians as early as 600 BC – over 300 years before his birth. ...more on Wikipedia about "Archimedes' screw"
An artesian aquifer is a confined aquifer whose water is pressurized. Water will thus flow out of an artesian well without pumping. ...more on Wikipedia about "Artesian aquifer"

The Australasian Bottled Water Institute Inc. or (ABWI) is a regional member of the International Council of Bottled Water Associations or(ICBWA). The regions covered are Australia, New Zealand and Oceana. The ABWI is the certifying organization for water bottlers in Australasia as well as the peak industry council. The Institute represents it's members to industry regulators, bureaucrats and media affiliations as well as regulates and provides information on all types of bottled water. The members (bottled water companies) also rely on the aid of the ABWI to assist in fulfillment of government requirements/standards in order to reach and sustain a high standard of quality in product. Previous to (unknown date) The ABWI was called the Australian Chapter of the International Bottled Water Association. ...more on Wikipedia about "Australasian Bottled Water Institute"
Bacterial water analysis is a routine check to make sure that the concentration of potentially pathogenic bacteria in drinking water is sufficiently low to say it is safe for human consumption at a reasonable level of confidence. ...more on Wikipedia about "Bacterial water analysis" Enjoy www.shortopedia.com. shortopedia
A significant fraction of the human body is water. This body water is distributed in different compartments in the body. Lean muscle tissue contains about 75% water. Blood contains 83% water, body fat contains 25% water and bone has 22% water. ...more on Wikipedia about "Body water"
Bubbler is a trademarked name that refers to a drinking fountain. The term is still used in several regional dialects of the United States such as in Wisconsin, Massachusetts, and Rhode Island, as well as in New South Wales, Australia. ...more on Wikipedia about "Bubbler"
The capillary fringe is the subsurface layer in which water molecules seep up from a water table by capillary action to fill pores. Pores at the base of the capillary fringe are filled with water due to tension saturation. This saturated portion of the capillary fringe is less than total capillary rise because of the presence of a mix in pore size. If pore size is small and relatively uniform, it is possible that soils can be completely saturated with water for several feet above the water table. Alternately, the saturated portion will extend only a few inches above the water table when pore size is large or non-uniform. Capillary action supports an unsaturated zone above the saturated base within which water content decreases with distance above the water table. In soils with a wide range in pore size, the unsaturated zone can be several times thicker than the saturated zone. ...more on Wikipedia about "Capillary fringe"
Chlorination is the process of adding the element chlorine to water as a method of water purification to make it fit for human consumption (potable). Water which has been treated with chlorine is effective in preventing the spread of disease. ...more on Wikipedia about "Chlorination"
Developed for use in Bangladesh, the cloth filter is a simple and cost-effective appropriate technology method for reducing the contamination of drinking water. ...more on Wikipedia about "Cloth filter"
The colour of a water sample is caused by both dissolved and particulate material in water, and is measured in Hazen Units (HU). Either of these components can be deeply coloured, for instance dissolved organic molecules called tannins can result in dark brown colours, or algae floating in the water ("particles") can impart a green colour. But in a lot of cases water is a clear to neutral colour due to a lack of pigments in the water. (e.g. the sea) ...more on Wikipedia about "Color of water"
Darcy's Law is a phenomologically derived constituative equation that describes the flow of a fluid through a porous medium (typically water through an aquifer). The law was formulated by Henry Darcy based on the results of 1855 and 1856 experiments on the flow of water through beds of sand. It, along with the conservation of mass, comprises the groundwater flow equation, which is one the basic building relationships of hydrogeology. ...more on Wikipedia about "Darcy's law"
Desalination or desalinization refers to any of several processes that remove the excess salt and other minerals from water in order to obtain fresh water suitable for animal consumption or irrigation, and if almost all of the salt is removed, for human consumption, sometimes producing table salt as a by-product. ...more on Wikipedia about "Desalination"

An estuary is a semi-enclosed coastal body of water which has a free connection with the open sea and within which sea water mixes with fresh water. The key feature of an estuary is that it is a mixing place for sea water and a significantly-sized river to supply fresh water. A tide is a necessary component to maintain a dynamic relationship between the two waters. Though something in the nature of an estuary can exist in a non-tidal sea, such areas go by names such as lagoon, étang or laguna. In non-tidal seas, the rivers naturally form deltas rather than estuaries. ...more on Wikipedia about "Estuary"
A water filter is a device which removes impurities from water by means of a fine physical barrier and/or chemical processes. Filters are used to cleanse water for irrigation, drinking water, aquariums, and swimming pools. Water Filters can be bought at stores to filter drinking water. Two major brands are PUR and Brita. These water filters remove things that are harmful to your health, things that can increase the chance of getting cancer, and things that taste or smell bad. ...more on Wikipedia about "Filter (water)"
A fire hydrant (also known colloquially as in fire plug in the USA, ) is a source of water provided in most urban, suburban, and rural areas with municipal water service to enable firefighters to tap into the municipal water supply to assist in extinguishing a fire. ...more on Wikipedia about "Fire hydrant"
Flocculation refers to a process where a solute comes out of solution in the form of floc or "flakes." The term is also used to refer to the process by which fine particulates are caused to clump together into floc. The floc may then float to the top of the liquid, settle to the bottom of the liquid, or can be readily filtered from the liquid. ...more on Wikipedia about "Flocculation"
The construction of a Flownet is a graphical method used to solve two- dimensional steady-state groundwater flow problems through aquifers. The method is often used in civil engineering, hydrogeology or soil mechanics as a first check for problems of flow under hydraulic structures like dams or sheet pile walls. ...more on Wikipedia about "Flownet"
In the mid-1980s, the Meteorological Service of Canada (MSC) began constructing and deploying large fog collecting devices on Mount Sutton in Quebec. These simple tools consisted of a large piece of canvas (generally 12 m long and 4 m high) stretched between two 6 m wooden poles held up by guy wires, with a long trough underneath. Water would condense out of the fog onto the canvas, coalesce into droplets, and then slide down to drip off of the bottom of the canvas and into the collecting trough below. ...more on Wikipedia about "Fog Collection"
A traditional fountain is an arrangement where water issues from a source ( Latin fons), fills a basin of some kind, and is drained away. ...more on Wikipedia about "Fountain"

Groundwater is water which may be flowing within aquifers below the water table. Within aquifers, the water flows through the pore spaces in unconsolidated sediments and the fractures of rocks. Groundwater is recharged from, and eventually flows to, the surface naturally; natural discharge often occurs at springs and seeps and can form oases or swamps. Groundwater is also often withdrawn for agricultural, municipal and industrial use through man-made wells. The study of the distribution and movement of groundwater is hydrogeology. ...more on Wikipedia about "Groundwater"
