"Groundwater flow is the movement of water that travels and seeps through soil and rock underground. Stored in cavities and geologic pores of the earth's crust, confined groundwater is under a great deal of pressure. Its upper part is lower than the material in which it is confined. Unconfined groundwater is the term for an aquifer with an exposed water surface."
Glacial moraine could dam and prevent glacial meltwater from escaping. Glacial lakes usually form behind the moraine as the thawing glacier retreats.

Electrical resistivity method is an excellent tool for groundwater exploration.Current is injected in ground through two electrodes and resultant potential is measured through another pair of electrodes. These electrode are placed on ground at predefined locations .Wenner and Schlumberger are the most widely used configuration for placing the electrodes.Sounding with Schlumberger configuration is carried out for groundwater investigation.The data is then interpreted with available software and the results are in the form of resistivity and the thickness of different layers.These can be gainfully correalated with available geological data and thus site for dugwell/tubewell can be finalised.The sea water intrusion,factories polluting discharge also can be successfully delineated with resistivity method
As water goes through ground, it will to a certain extent dissolve some minerals. When water later drips down inside a cave, the water can actually deposit a little bit of the minerals it is carrying. This results in Stalactites from roof and Stalagmites at ground. It is true.

Groundwater is as prone to contamination as surface water. Groundwater contamination results from the infiltration of spills at the surface, leachate from tanks. pipelines and buried waste. Groundwater may also be contaminated by naturally occurring salts, metals, organics and gases in the soil.
It is healthy for plants and for the environment too because it keeps chemicals from ordinary fertilizers from getting into groundwater. That's important because we drink groundwater and water from streams. However, it takes longer to see results of organic fertilizers.

The term UFE, medically, refers to Uterine Fibroid Embolization, a procedure typically performed by a radiologist. The results determine whether or not too much blood is flowing to a woman's fibroids.
70 degree Celsius is qiute a high temperature. in this temperature, the water molecules starts escaping which results in the vapourisation of water.
Budd-Chiari syndrome is a rare problem that results from blood clotting in the veins flowing out of the liver (hepatic veins).

In general a tracer is a substance that can be used e.g. to monitor how a process runs or a volume of material is transported in a medium. The tracer is part of the system that is inspected. Anything can be taken as tracer which is suitable to monitor these processes closely and whose specific property (isotopic ratio, concentration, colour etc.) can be measured sufficiently precisely to allow for a sound interpretation of experimental results. Isotopic tracers can for example be used to monitor how groundwater flows in an aquifer, but for the same purpuses one can also use elemental or molecular tracers.
Yes. Specific to the BP spill, I feel that it is a very remote possibility at this point. There was an article recently that oil was found "inland" in Florida, but to go any distance inland is very difficult as the fresh water streams and rivers all flow outwards to the Gulf and Atlantic ocean. I don't know of any case where an offshore oil spill (tanker accident, offshore blow-outs) contaminate groundwater. There have been some oil spills as a result of war (Iran-Iraq war, Nigerian civil war, Angola, Gulf war) where some groundwater conamination could be possible. Groundwater contamination does occur from oil and other hazardous chemicals seeping into the ground and ultimately contaminating the aquifer. There are numerous cases of leakage from leaking storage tanks, settling pits, pipelines and water injection wells (all related to the oil industry) causing groundwater contamination. Gasoline station storage tanks leakage can cause groundwater contamination. Of course, within the US, any activity that results in contamination of drinking water sources, will be immediately shut down. Gas stations are under strict federal regulations as to the specifications of gasoline storage tanks.
i its because circles are more consistant and flowing for this particular model.it yeailds better results that the alternative square shape.
