As with all "fake news" that percolates through social media and across the political spectrum, the stories' accuracy is less important than their use as "a marker of identity, a way to proclaim your affinity with a particular community," as Judith Donath, a professor at MIT's Media Lab, puts it.

These sorts of conditions can persist over several years, even with above average rainfall, as the rainfall only slowly percolates through the water stores and replenishes them.

Since the Fifties the industrial refuses received different attention and their disposal requirements improved. Leachate, the contaminated liquid which percolates through landfill material, was not prevented and this resulted in cases of environmental damages.

Anaerobic wetlands may be lined or unlined shallow ponds filled with organic matter, such as compost, and underlain by limestone gravel. Water percolates through the compost, becomes anaerobic and metals precipitate as sulfides. Microorganisms facilitate this reaction by first consuming oxygen. Alkalinity and H2S are produced.

Water is collected or generated on Kwajalein Island and distributed by barge to Meck, Illeginni, and Gugeegue. Kwaj collects rainfall from the runway into a catch basin where it is stored and treated. A secondary source is from "skim wells" on Kwaj and Roi-Namur. Rain percolates through the coral during the wet season.

The liquid encased is petroleum, and the gas bubble is methane. Enhydros are formed when water rich in silica percolates through volcanic rock, forming layers of deposited mineral. As layers build up, the mineral forms a cavity in which the water becomes trapped. The cavity is then layered with the silica-rich water, forming its shell.

When precipitation falls on open landfills, water percolates through the garbage and becomes contaminated with suspended and dissolved material, forming leachate. If this is not contained it can contaminate groundwater. All modern landfill sites use a combination of impermeable liners several metres thick, geologically stable sites and collection systems to contain and capture this leachate. It can then be treated and evaporated.

A recent development in forensic science is the isotopic analysis of hair strands. Hair has a recognisable growth rate of 9-11mm per month or 15 cm per year. Human hair growth is primarily a function of diet, especially drinking water intake. The stable isotopic ratios of drinking water are a function of location, and the geology that the water percolates through.

The plain may support fresh water wetlands or Sitka Spruce forests following uplift events and salt marsh or inundated shellfish beds following subsidence events. The relatively small catchment basin tributary to Freshwater Lagoon has allowed formation of a durable coastal sand bar which has not been breached by recent storm events. Precipitation usually percolates through the bar without forming a surface channel.

For example, unemployed home builders can be hired to expand highways. Tax cuts allow consumers to increase their spending, which boosts aggregate demand. Both tax cuts and spending have multiplier effects where the initial increase in demand from the policy percolates through the economy and generates additional economic activity. The effects of fiscal policy can be limited by crowding out.

Infiltration reclaims stormwater runoff and allows for groundwater recharge. Runoff enters the soil and percolates through to the subsurface. The rate of infiltration is affected by soil compaction and storage capacity, and will decrease as the soil becomes saturated. The soil texture and structure, vegetation types and cover, water content of the soil, soil temperature, and rainfall intensity all play a role in controlling infiltration rate and capacity.

These are formed when rainwater - a weak carbonic acid capable of dissolving limestone - percolates through it via the grykes and joints underground. This means the limestone is pervious. As this happens the limestone is dissolved and removed in solution. Caverns are often found below the surface in the limestone and as the lime-rich water finds its way underground it begins to drip from the roof of the cavern.
|
|
These are formed when rain falls on the highly acidic topsoil. The water increases in acidity as it percolates through the topsoil then dissolves the underlying chalk. Eventually there is nothing but topsoil above the caverns so formed and the familiar shape of a doline is created when the topsoil collapses into the cavern beneath. Dolines are usually shaped like a teardrop cut in half vertically and laid down horizontally.

A large percentage of precipitation passes through the canopy. This provides a protective snow cover in winter and in warm seasons precipitation percolates through the leaf cover to nourish plants which require surface soil moisture. The result of the above factors is an extensive understory of vegetation in the aspen forest. Common shrubs and herbs are: saskatoon, red-osier dogwood, raspberry, wild rose, currants and bracted honeysuckle, wild sarsaparilla, hairy lungwort, asters, and peavine.

The hot mineral water emerges from the ground between 110 °F to 151 °F. Colonies of cyanobacteria grow in the spring, coloring areas along the edges with white, yellow and orange residue. Rainwater percolates through a deep fracture in the bedrock where it is heated by magma and emerges through rocks near the surface. Granitic rocks of the hot springs pluton have intruded on the south side of the Caribou Mountain complex.

The lymph capillaries drain the lymph to larger contractile lymphatics, which have valves as well as smooth muscle walls. These are called the collecting lymphatics. As the collecting lymph vessel accumulates lymph from more and more lymph capillaries in its course, it becomes larger and is called the afferent lymph vessel as it enters a lymphs node. Here the lymph percolates through the lymph node tissue and is removed by the efferent lymph vessel.

Blood also flows from branches of the hepatic artery and mixes in the sinusoids to supply the hepatocytes with oxygen. This mixture percolates through the sinusoids and collects in a central vein which drains into the hepatic vein. The hepatic vein subsequently drains into the inferior vena cava. The hepatic artery provides 30 to 40% of the oxygen to the liver, while only accounting for 25% of the total liver blood flow.

The first is 'heap' leaching in which the dilute cyanide solution is sprayed on large piles or heaps of coarse gold ore. The solution percolates through the pile dissolving the gold and the pregnant solution is then collected. This method is mainly used for ore with lower concentrations of gold. The other method is 'vat' leaching in which the process is similar but the gold ore is finely ground and leaching takes place in a tank or vat.

Fumigation generally involves the following phases: First, the area intended for fumigation is covered to create a sealed environment. Next, the fumigant is released into the space to be fumigated. The space is held for a set period while the fumigant gas percolates through the space and acts on/kills any infestation in the area. Finally, the space is ventilated so that the poisonous gases are allowed to escape from the space, rendering it safe for humans to enter.

Today the water percolates through the landslide debris to form the source of the Doye. In dry summers the level of the lake can fall by 5m, whereas during wet periods, the level can rise to a point where the water also flows out towards Saint-Germain-de-Joux and Bellegarde-sur-Valserine, at the other end of the water gap, via the Combet stream, which flows into the Semine then the Valserine, which flows into the Rhône.

Instead, rain water percolates through the rock, and may spend 25 years underground before emerging 50 kilometres away at Mzima. The natural filtration process gives rise to Mzima's famously clear stream, which flows through a series of pools and rapids. Two kilometres downstream from the springs, the stream is blocked by a solidified lava flow and disappears below the surface again. Mzima is one of Tsavo's most popular wildlife attractions owing to its resident populations of hippos and Nile crocodiles.

When water percolates through waste, it promotes and assists the process of decomposition by bacteria and fungi. These processes in turn release by- products of decomposition and rapidly use up any available oxygen, creating an anoxic environment. In actively decomposing waste, the temperature rises and the pH falls rapidly with the result that many metal ions that are relatively insoluble at neutral pH become dissolved in the developing leachate. The decomposition processes themselves release more water, which adds to the volume of leachate.

The water percolates through the sand at a rate of 10 cm an hour, gradually leaving a fine film of sediment. The rapid primary filters were cleaned by an upward passage of compressed air and clean water. The compressed air broke up the surface deposit, and the water carried it away. To clean the main filter beds all the water was drained out, and the layer of sediment, with some 2 cm of sand under it, was scraped off manually.

In contrast, during interglacial and interstadial periods, more effective coupling occurred between the surface drainage network and the internal karst drainage system.Woodward, Hamlin, Macklin, Hughes, Lewin 2008, p. 63 Since limestone dissolves as the water percolates through its pores, an extended underground drainage system has developed, with caves and channels that enlarge with time when their roofs collapse, producing rocky exposures and perpendicular slopes, which is also the reason why the water is scarce. Only when an impenetrable stratum is met, does water appear on the surface.

With coal mining, waste materials are piled at the surface of the mine, creating aboveground runoff that pollutes and alters the flow of regional streams. As rain percolates through waste piles, soluble components are dissolved in the runoff and cause elevated total dissolved solids (TDS) levels in local water bodies. Sulfates, calcium, carbonates and bicarbonates – the typical runoff products of coalmine waste materials – make water unusable for industry or agriculture and undrinkable for humans. Acid mine wastewater can drain into groundwater, causing significant contamination.

The rain percolates through limestone aquifers to a depth of between where geothermal energy raises the water's temperature to between 64 and 96 °C (approximately 147–205 °F). Under pressure, the heated water rises to the surface along fissures and faults in the limestone. Hot water at a temperature of rises here at the rate of daily, from the Pennyquick geological fault. In 1983, a new spa-water bore-hole was sunk, providing a clean and safe supply for drinking in the Pump Room.

The insulation of lanky moss prevents the roots from freezing if there is an unexpected drop in temperature. They can also help retain moisture in the soil so if there is a dry season in the forest they can help keep the trees and other plant species hydrated. Aside from water retention they can also hold large levels of nutrients. As rain percolates through the forest’s canopy, nutrients such as nitrogen flows off with the water and is immediately absorbed by the lanky moss that is growing on the forest floor.

Lake Amtkeli is fed by the Amtkeli River, but only a small part of its water percolates through the obstructing rubble back into the river. The greater part leaves the lake through underground passages to the Jampal River. Due to the lake's limited discharge capacity, its water level rises strongly during snowmelt in May, leading to annual fluctuations of up to in the lake's average height above sea level and maximal depth, and increasing its length from to . The average surface area of Lake Amtkeli is , and its drainage basin measures .

A bathtub faucet with built-up calcification from hard water in Southern Arizona. Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. Hard drinking water may have moderate health benefits, but can pose critical problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water.

The first is an arid desert absolutely barren along part of the coast, between Arica and Copiapó, but with a coarse scanty vegetation near the Cordilleras along watercourses and on the slopes where moisture from the melting snows above percolates through the sand. The altiplano of the northernmost portion of the Chilean territory is home to the Browningia candelaris, a candelabrum- shaped cactus. Another cactus species, the Echinopsis atacamensis, grows in the pre-Andean area. The high Andean region is also characterized by the presence of species of the genus Polylepis and the Azorella compacta.

The hills consist of Precambrian igneous and metamorphic rock, the oldest of which are about 670 million years old. The rocks are characterised by low porosity and high secondary permeability via fissures. Malvern water is rainwater and snow meltwater that percolates through fissures created by the pressures of tectonic movements about 300 million years ago when advancing sedimentary layers of Silurian shale and limestone were pushed into and under older Precambrian rock. When the fissures are saturated, a water table forms and the water emerges as springs around the fault lines between the strata.

Precipitation and surface water leaches dissolved organic carbon (DOC) from vegetation and plant litter and percolates through the soil column to the saturated zone. The concentration, composition, and bioavailability of DOC are altered during transport through the soil column by various physicochemical and biological processes, including sorption, desorption, biodegradation and biosynthesis. Hydrophobic molecules are preferentially partitioned onto soil minerals and have a longer retention time in soils than hydrophilic molecules. The hydrophobicity and retention time of colloids and dissolved molecules in soils are controlled by their size, polarity, charge, and bioavailability.

Silfra is spring fed by groundwater originating as meltwater from Langjökull, Iceland's second largest glacier, about fifty kilometres north of the Þingvallavatn Lake. In the distant past, this Langjökull meltwater ran through a river directly and unimpeded into the Þingvallavatn Lake. This river was blocked a few thousand years ago by lava flows from the Skjaldbreiður volcano causing the meltwater to pond and seep underground into the porous lava rock to form an aquifer. This water then percolates through the aquifer for thirty to a hundred years before emerging from the fissure springs in the Þingvallavatn Lake fifty kilometres to the south.

The Santa Ana River is included on the U.S. Environmental Protection Agency's (EPA) list of "304 (l) 'toxic hot spots' list of impaired waterways". In Orange County, the Orange County Water District, formed in 1932 to manage the county's groundwater, uses the treated water from upstream to recharge a massive reservoir, or aquifer, that runs roughly nine miles from Lakeview Avenue to Ball Road. The water percolates through layers of sand and gravel, which work to scrub, or purify it. There, it joins treated wastewater pumped from the Orange County Sanitation Department's state-of-the-art plant in Fountain Valley.

The rocks are characterised by low porosity and high secondary permeability via fissures. Malvern water is rainwater and snow meltwater that percolates through fissures created by the pressures of tectonic movements about 300 million years ago when advancing sedimentary layers of Silurian shale and limestone were pushed into and under older Precambrian rock. When the fissures are saturated, a water table forms and the water emerges as springs around the fault lines between the strata. Depending on rainfall, the flow can vary from as little as 36 litres (8 gallons) per minute to over 350 litres (77 gallons) per minute.

First, the city applies treated wastewater to crops at the Lubbock Land Application Site – a site located east of the City of Lubbock. Here, 31 center-pivot sprinkler systems are used to irrigate crops with 13 million gallons of treated effluent per day. The soils and sediments of the Land Application Site act as filters as the treated wastewater percolates through the soil. To minimize contamination of the Ogallala Aquifer, groundwater is then pumped from beneath the Land Application Site to Canyon Lakes, where the water flows from one lake to the next and eventually into Yellow House Canyon, forming the North Fork Double Mountain Fork Brazos River.

Sugarcane diffusion is the process of extracting the sucrose from the cane with the use of imbibition but without the squeezing by mills. Shredded cane is introduced into the diffuser at the feed end, Hot water is poured over the shredded cane just before the discharge end of the diffuser. The hot water percolates through the bed of cane and removes sucrose from the cane. This dilute juice is then collected in a compartment under the bed of cane and is pumped to a point a little closer to the feed end of the diffuser and this dilute juice is allowed to percolate through the bed of cane.

A major problem with this approach was that the taste of the cloth filter - whether cotton, burlap or an old sock - transferred to the taste of the coffee. Around the same time, a French inventor developed the "pumping percolator", in which boiling water in a bottom chamber forces itself up a tube and then trickles (percolates) through the ground coffee back into the bottom chamber. Among other French innovations, Count Rumford, an eccentric American scientist residing in Paris, developed a French Drip Pot with an insulating water jacket to keep the coffee hot. Also, the first metal filter was developed and patented by a French inventor.

Diego Garcia is the above- water rim of a coral atoll composed of Holocene coral rubble and sand to the depth of about , overlaying Pleistocene limestone deposited at the then-sea level on top of a seamount rising about from the floor of the Indian Ocean. The Holocene sediments are porous and completely saturated with sea water. Any rain falling on the above-water rim quickly percolates through the surface sand and encounters the salt water underneath. Diego Garcia is of sufficient width to minimise tidal fluctuations in the aquifer, and the rainfall (in excess of 102.5 inches/260 cm per year on average)Natural Resources Management Plan (2005), paragraph 2.5.2.

Dump leaching is an industrial process to extract precious metals and copper from ores.. Dump leaching is similar to heap leaching, however in the case of dump leaching ore is taken directly from the mine and stacked on the leach pad without crushing where, in the case of gold and silver, the dump is irrigated with a dilute cyanide solution that percolates through the ore to dissolve gold and silver. The solution containing gold and silver exits the base of the dump, is collected and precious metals extracted. The resultant barren solution is recharged with additional cyanide and returned to the dump. This method of leaching is usually suitable for low grade ores because it is very low cost.

Because private maintenance efforts during the 1970s and early 1980s proved inadequate, the government initiated repair and maintenance of the falaj system to increase the quantity of water available to cultivated areas. The cooler climate on the high plateau of the Al Jabal al Akhdar enables the growing of apricots, grapes, peaches, and walnuts. The Al Batinah coastal plain accounts for about two fifths of the land area under cultivation and is the most concentrated farming area of the country. Annual rainfall along the coast is minimal, but moisture falling on the mountains percolates through permeable strata to the coastal strip, providing a source of underground water only about two meters below the surface.

Numerous researchers have studied the hydrodynamics of CFB (Yang, 1998; Basu, 2006; Rhodes, 2008; Scala, 2013). The fluidization is a function of several parameters such as the particles’ shape, size and density, velocity of the gas, beds' geometries etc. Kunii and Levenspiel (1991), Oka and Dekker (2004), and Souza-Santos (2004) defined the regimes of fluidization as described below: (a) Fixed Bed: When the fluid is passed through the bottom of the bed at a low flow rate, the fluid merely percolates through the void spaces between stationary particles. (b) Minimum fluidization: When the gas velocity reaches (Umf) minimum fluidization velocity, and all the particles are just suspended by the upward flowing fluid.

Soil absorbs rainwater and releases it later, thus preventing floods and drought, flood regulation being one of the major ecosystem services provided by soil. Soil cleans water as it percolates through it. Soil is the habitat for many organisms: the major part of known and unknown biodiversity is in the soil, in the form of invertebrates (earthworms, woodlice, millipedes, centipedes, snails, slugs, mites, springtails, enchytraeids, nematodes, protists), bacteria, archaea, fungi and algae; and most organisms living above ground have part of them (plants) or spend part of their life cycle (insects) below- ground. Above-ground and below-ground biodiversities are tightly interconnected, making soil protection of paramount importance for any restoration or conservation plan.

Darent and other Rivers of Kent Orpington pond is the source of the River Cray The River Cray is the largest tributary of the Darent. It is the prime river of outer, south-east Greater London, rising in Priory Gardens, Orpington, where rainwater percolates through the chalk bedrock of the Downs to form a pond where the eroded ground elevation gives way to impermeable clay. Initially it flows true to form northwards, past industrial and residential St Mary Cray, through St Paul's Cray (where it once powered a paper mill) and through Foots Cray, where it enters the parkland Foots Cray Meadows, flowing under by Five Arches bridge (built in 1781 as part of their designs by Capability Brown). It then flows by restored Loring Hall (c.

The amount, location, and timing of water reaching a drainage channel from natural precipitation and controlled or uncontrolled reservoir releases determines the flow at downstream locations. Some precipitation evaporates, some slowly percolates through soil, some may be temporarily sequestered as snow or ice, and some may produce rapid runoff from surfaces including rock, pavement, roofs, and saturated or frozen ground. The fraction of incident precipitation promptly reaching a drainage channel has been observed from nil for light rain on dry, level ground to as high as 170 percent for warm rain on accumulated snow.Babbitt, Harold E. & Doland, James J., Water Supply Engineering, McGraw-Hill Book Company, 1949 Most precipitation records are based on a measured depth of water received within a fixed time interval.

The talus, which primarily consists of Middle Stone Age deposit, rock fall and unconsolidated sediments, is stabilized by an area of large, exposed blocks (14 m²). At some stage – and in between the prehistoric occupation of the cave site – these blocks have fallen down from the rock face above, effectively preventing site erosion and allowing sediments to stabilize and accumulate in front of the cave's drip line. Calcium carbonate (CaCO₃) rich ground water seeps in from the cave roof and percolates through the interior sediments, resulting in an alkaline environment with good preservation conditions. The excavated Middle Stone Age deposit in Blombos Cave consists of aeolian (wind-borne) dune sand, blown in through the cave entrance, and roof spall from the cave ceiling.

Carshalton Pond, London Borough of Sutton River Wandle at Beddington Park in the London Borough of Sutton In the pleistocene before the carving of the Mole Gap, water lapped the north of the area between the North Downs and Greensand Hills known as the Vale of Holmesdale taking the Caterham or Coulsdon Bourne routes, to form the much less deep Merstham Gap, a wind gap.Natural England - Geodiversity In more recent times, precipitation on the local central, small section of the long escarpment percolates through the chalk and reappears as springs in central Croydon, Beddington, and Carshalton. The occasional stream, known as the Bourne, which runs through the Caterham valley (and Smitham Bottom in Coulsdon) is a source of the River Wandle but only surfaces after heavy rainfall. A series of ditches and culverts carries the water from Purley to Croydon.

A birdhouse at the SJWS Sunset at the SJWS A black-necked stilt at the SJWS The San Joaquin Wildlife Sanctuary is a constructed wetland in Irvine, California, in the flood plain of San Diego Creek just above its outlet into the Upper Newport Bay. The site is owned by the Irvine Ranch Water District; it was used for farmland in the 1950s and 1960s, and (prior to its reconstruction) as a duck hunting range. Restoration of the wetlands began in 1988 and was completed in 2000.. Now, the site serves a dual purpose of removing nitrates from the creek water and providing a bird habitat. The water district also operates an adjacent wastewater treatment facility but the treated wastewater does not enter the wildlife sanctuary.. Within the sanctuary, water from the creek percolates through a system of ponds, constructed in 1997 and ringed with bulrushes; the ponds are periodically drained and re-seeded, and the surrounding land is covered with native plants.
