Water dissolves more substances than any other and is known as the "universal solvent. The period during which surface water remains on a wetland. Air stripping towers are vertical cylindrical air stripping devices are often used in ground water remediation at sites where gasoline has contaminated ground water.Alignment (well alignment)A measure of the “vertical straightness” of a well. Anatomy of a Well: Casing. By some definitions, seepage is the process and springs are the result.(2.) Large spaces between the organic or mineral particles in soils which give rise to high permeability. See also ASR.Ground water miningLong term pumping water from an aquifer system at a rate greater than natural recharge. The horizontal radial distance from a well to the points in an aquifer where there is no observable influence from pumping. It is also called as water table well. Typically expressed in milligrams of dry sediment per liter of water sediment mixture. The environment in which the life needs of organisms/ plants/ animal populations is supplied. Some call it “the gift.” Others refer to it as “dowsing,” “doodlebugging,” or “water witching”—the practice of locating water underground using a forked stick. Many creeks are intermittent and flow only after rain. Persons who own land adjacent to a stream have the right to make reasonable use of the stream. Injection wells are generally drilled into rock formations that don't deliver drinking water, unused aquifers, or below freshwater levels.InorganicNot derived from or made of living matter. A substance that has a pH of more than 7, which is neutral. Analytical ModelComputer model that uses mathematical equations as a basis to describe ground water flow.Anisotropic aquiferAn aquifer with sediments/ rock structures that result in different vertical and horizontal hydraulic properties.See also isotropic aquiferAnnulus (Annular space)The space between a drilled hole and the well casing. Thick deposits of glacial outwash may provide excellent aquifers.Glacial TillAn unsorted, and often compacted mixture of clays, sands, rocks, and boulders deposited by melting glaciers.GlacierA mass of ice, formed by the compaction and recrystalization of snow, that moves very slowly down slope (valley glacier) or outward (ice sheet) due to its own weight. The coefficient of transmissibility is the rate of flow of water, at the prevailing water temperature, in gallons per day, through a vertical strip of the aquifer one foot wide, extending the full saturated height of the aquifer under a hydraulic gradient of 100 percent. Large drainage basins, like the area that drains into the Mississippi River contain thousands of smaller drainage basins. Point source pollutionWater pollution coming from a single point, such as a sewage outflow pipe.See also non-point source pollutionPollutantSubstances such as solid waste, sewage, garbage, sewage sludge, radioactive materials, industrial, municipal, and agricultural waste that can detrimentally affect the quality of water.PorosityDescribes the amount of water that can be stored in a rock formation. Pressure from a pump is used to reverse the normal osmotic process resulting in the solvent moving from a solution of higher concentration to one of lower concentration. Fifteen million US homes have their own water well.Septic tankA tank (usually made of concrete) used to detain domestic wastewater to allow the settling of solids prior to distribution to a leach field for soil absorption. The oldest and most common kind of well is a water well, to access groundwater in underground aquifers. A water supply system that supplies less than 25 people (less than 15 connections) and which is used for a transient populations such as in a roadside café, bed & breakfast or gas station. Peat is organic. Water Underground Vocabulary for Mrs. Sebastian's class. WithdrawalWater removed from a ground or surface water source for use. They’re located inside the casing of the well. The most common of which are trihalomethanes that can result from chlorine combining with naturally occurring carbon.Diversion - Removing water from rivers or lakes by pumping or by structures such as a ditch, canal or siphon.Domestic water useWater used for household purposes, such as drinking, food preparation, bathing, washing clothes, dishes, flushing toilets, and watering lawns and gardens. Why doesn’t lightning travel in a straight line? It can also be drawn up using containers, such as buckets that are raised mechanically or by hand. (Occasionally tests may add water to a well). Riparian areas are often protected by laws requiring “buffer strips” that can’t be developed or cultivated.See also BMP.Rotary drillingA well drilling method achieved by the rotary action of a drill bit. If you had 10,Billion dollars what would you do? The well is 1285 feet deep — that is as deep as the Empire State Building is tall (remember it is hand-dug!) STUDY. Percolation is usually used to describe saturated flow infiltration.See also percolationInjection wellA well constructed for the purpose of injecting directly into the ground. Channel flowSurface water flow within the boundaries of a defined natural channel, e.g., streams and rivers.ChlorineAn effective oxidizing agent used in water treatment. Unconsolidated RockA rock that consists of fragments of weathered rock material (including sands, gravels and cobbles) that are not cemented to form solid rock. Underground water sources include:Wells: dug wells (shallow) and bored wells (deep)Springs: Artesian springs and surface springsSeeps such as oases. Drilled water wells in solid rock are typically up to 300 feet deep. Erosion from bedrock may occur because of the presence of abrasive particles.EskerA feature of glacial deposition, formed of sands and gravels which occur in elongated and often sinuous ridges. If casing is installed as the drilling proceeds then reverse-rotary drilling may be used with the drilling fluid being pumped down the outside of the drill pipe and returned to the surface upwards through the drill pipe.RunoffThe movement of water over the surface of the land, derived from snowmelt or rainfall (as opposed to water infiltrating the ground and moving to streams as baseflow). This water is available for uptake by plants.SoluteA substance that is dissolved in another substance, thus forming a solution.SolventA substance that dissolves other substances, thus forming a solution. Storm water interception refers to the use of engineering structures to delay the flow effects from storms from reaching rivers and hence reduce the risk of flood damage.InterflowWater that infiltrates the soil surface, and then moves laterally through the upper soil layers towards stream channels and other water bodies (lakes and wetlands). A hydraulic gradient of 100 percent means a one foot drop in head in one foot of flow distance.TranspirationThe process by which water that is absorbed by plants, usually through the roots, is evaporated into the atmosphere from the plant surface, via stomata (tiny pores) on the leaves and stems.See also evapotranspiration. Most sedimentary rocks are clastic.ClayFine grained sediment derived from the weathering of rock minerals. Water drops on the outside of a cold glass of water are condensed water. Design and selection of well screens is based of geologic and hydraulic criteria. If you are looking to drill a water well, you want to know where to drill before going to the expense of drilling a water well. Use of the term aquifer is usually restricted to those water-bearing formations capable of yielding water in sufficient quantity to constitute a usable supply source.See confined aquifer, unconfined aquifer.Aquifer testHydraulic test of an aquifer based on calculations using data from measurements of ground water level response (drawdown and recovery) to controlled pumping. In spray irrigation there is greater likelihood of water being lost to evaporation.Spreading BasinsAreas used for the purpose of recharging aquifers. Permeability is related to the size of openings and fissures in solid rock; the nature of the particles in unconsolidated organic and inorganic sediments, and the extent to which the void spaces are interconnected. The selection of well screen design and opening size may depend on characteristics of the geologic formation, required yield and the thickness of the aquifer.See also Grain sizeSeawater intrusion (salt water intrusion)The inland movement of saline water in coastal aquifers. A well constructed in a specific location for the purpose of observing(measuring) changes in water level. Aquifers are layers of rock and soil with water flowing through their small pores. There are three types with respect to the type of flow. Buildings, roads, etc. Apart from it, other sources are those in which groundwater becomes again available on the surface of the earth. Wells not in use, but which are properly capped may be referred to as out-of-use wells. Within permafrost areas they may be seasonal melting and areas of discontinuous permafrost. Many former kettle hole lakes resulting from the last glaciation (approximately 10,000 years ago in North America) are undergoing paludification.PalustrineFresh water wetland environments, other than those located along a river or lake, dominated by trees, shrubs, emergent vegetation, mosses or lichens.Particle sizeThe diameter of sediments. Atmospheric pollutants may also reach the ground in particulate form independent of rainfall. The doctrine of riparian rights has its origins in English common law. Most bentonite in the U.S. is mined in Wyoming.Best Management Practices (BMP)Sensible land management strategies that can reduce the potential for non-point source pollution from dissolved or particulate contaminants.BicarbonateAlkilinity in water is usually composed of bicarbonate and is reported as mg/L CaCO3.BitThe cutting tool used in well drilling. About 15% of the USA’s population supply their own water, mainly from wells.Drainage basinThe topographic land area that contributes flow to a river/ lake/wetland as defined by a particular point of reference. Typical forms of NPS pollution result from sediment, nutrients, organic and toxic substances originating from land-use activities, which are carried to lakes and streams by surface runoff. Water in the saturated zone, below the water table, is called groundwater. Changes in oxygen levels in aquifers can result in changes in ground water chemistry.PaludificationThe natural process of vegetation growth in lakes leading to their eventual infilling with accumulations of plant growth and decaying organic material. In some parts of the US any well drilled into bedrock is (incorrectly) called an artesian well. Coal is a rock of organic origin. How to find Water and Water Table Depth Underground. The definition is similar to that for springs, however, the movement of ground water to the surface is often slower and generally not as concentrated as in springs. Groundwater does not stay underground forever, and it does not stay still waiting for us to draw it out. Ground water at the coast may reach the oceans via coastal discharge at or beyond the shore zone. Today, the casing is usually made of PVC. Most clays are considered impermeable even although flow may in fact occur at extremely slow rates.Impervious AreaImpermeable surfaces, such as pavement or rooftops, which prevent the infiltration of water into the soil.Induced infiltration (induced recharge)Pumping from wells adjacent to rivers of lakes that results in river/lake bed flow to the adjacent aquifer.InfiltrationThe downward movement of water into soil and rock formations. https://practicalpreppers.com/consultationBefore drilling a well, or putting in a new pump, consider getting one of these! Wells which contain pressurized water are called ordinary wells. In very flat areas, wetland watersheds are difficult to define. See also sand & gravel aquifers, stratified drift.AnaerobicA condition of oxygen deficiency found in some saturated soils. Generally, any viruses, bacteria, or fungi that may cause disease.PCB (Polychlorinated biphenyls)A group of synthetic, toxic chemical compounds which are chemically inert and not biodegradable (in the past these were often used in making paint and electrical transformers),. Igneous rocksRocks formed by the solidification of magma. A flow of one million gallons per day for one year equals 1,120 acre-feet (365 million gallons).Monitoring wellA well constructed or used for the purposes of water level or water quality data collection. Based on conservative risk-assessment methodology, the MCL is the greatest amount of a contaminant that can be present in drinking water without causing a risk to human health.Metamorphic rockA rock type formed from pre-existing rocks/ sediments as a result of heat and/or pressure. Aside from housing the equipment, it also serves as a barrier to keep underground contaminants from entering the well and mixing with the water. The well water is drawn up by a pump, or using containers, such as buckets, that are raised mechanically or by hand. Aquicludes do not yield significant amounts of water to wells but may be important as water storage zones that release water to more permeable formations.Aquifer rechargeThe process/processes by which water from precipitation (or some other part of the hydrologic system) reaches and hence increments stores of ground water.Aquifer(1. To prevent the risk of contamination, abandoned wells should be sealed from the bottom up. They are mainly springs, wells, and geysers.Such water is considered to have been generated in the interior of the earth. Changes of oxygen levels in soils and rock sediments can have important effects on ground water chemistry. WetfallThe deposition of pollutants on the land surface washed out of the atmospheric by precipitation. The water table may be located at or near the land surface, or at some depth below the land surface. Caused by surface tension forces in the pore spaces of the rock, soil or vegetation layers that are not fully saturated. Rapid cooling results in small mineral grain size. The level below the water table in an unconfined aquifer. Ground water discharge and recharge are commonly linked in water budget calculations.Ground water (unconfined)Water in an aquifer that has a water table that is at atmospheric pressure.Ground water bankingA water management strategy whereby an agency “sells or rents” excess storage space in aquifers. Depending on local geologic and hydrologic conditions a stream may lose and gain flow as water moves through the hydrologic system.See also gaining streamLotic watersFlowing waters, as in streams and rivers.MacroporesLarge spaces between the organic or mineral particles in soils which give rise to high permeability.Maximum contaminant level (MCL)Designation given by the U.S. Environmental Protection Agency (EPA) to water quality standards promulgated under the Safe Drinking Water Act. You can still visit the well today! Permeable. These include the casing, which allows water to flow up from an aquifer and reach a pump embedded inside the casing. Technologies include electrical resistivity, gamma-log, acoustic etc.GeyserA hydrologic spring-like feature from which hot water and steam reach the earth’s surface. A feature of glacial deposition. Sediment Type Size in inches size in millimeters, Boulder greater than 10.8 greater than 256, Very Fine Sand 0.002 - 0.005 0.063 - 0.125. Much of the water transferred from north to south in California and other western states is conveyed by aqueducts.AquicludeA saturated rock formation or layer of geologic sediments with low permeability. from a water-pumping windmill. Usually used to describe wells used for injecting treated (or untreated) wastewater. Gage height is often used interchangeably with the term river stage.Gaging stationPrincipally used to designate a site on a stream, lake or reservoir where hydrologic data are obtained. How many signers of the Declaration of Independence became president? wetlands, rivers, upland. Some of these can further be divided into smaller elements, for example, the well, besides the tubing string, may … They have depth of 80 meter or more. Clay can store water but not transmit water. Well hydrographs show changes of ground water levels vs. time.Hydrologic SystemA more accurate way of describing the many processes involved in the hydrologic cycle.Hydrologic cycleA description of the circulation of water on Earth involving transfers and storage of water vapor from the Earth's surface via evapotranspiration into the atmosphere, from the atmosphere via precipitation back to earth, and through infiltration to ground water, runoff into streams, rivers, and lakes, and ultimately into the oceans.. The high costs of energy make desalinized water expensive.Developed WaterWater in a specific area that has been added to the hydrologic water system through engineering strategies. In some parts of the US any well drilled into bedrock is (incorrectly) called an artesian well.Artificial rechargeA process where water is put back into ground water storage by use of engineering devices such as spreading basins or recharge wells.See also ASRASR (Aquifer Storage Recovery)A management strategy involving engineered devices such as detention ponds or recharge wells that deliberately adds water to ground water storage with a view to later withdrawal for some economic purpose. The first person to take a quantity of water and put it to beneficial use has a higher priority of right than a subsequent user. Get help with a project!
