Is groundwater harder to clean up than surface water?
Yes, because its more complex to clean up groundwater than surface water.
Chemicals and pesticides get into groundwater supplies through?
Sometimes referred to as groundwater contamination, groundwater pollution is not as easily classified as surface water pollution, as contamination may not be easy to recognise. Groundwater, by it's very nature, is more susceptable to contamination from sources that may not directly affect surface water bodies. Groundwater can become contaminated by those drilling for oil or gas wells. Groundwater may be polluted through a spill or ongoing realease of chemical or radionuclide contaminents into soil, polluting the aquifer below yet not the surface water body above. This is defined as a toxin plume, and as it travels it is defined as a plume front. Analysis of groundwater pollution usually focuses on the soil characteristics, geology, hydrogeology, hydrolgy and the nature of the contaminants at the site.
What is groundwater depletion?
Ground water depletion is when all the ground water is pumped out of an aquifer and no more groundwater is left. This causes the water table to sink and lakes and rivers to sink as well. USE WATER RESPONSIBLY.
What does it mean when the water table is near the earths surface?
The water table is the level at which the submarine pressure is far from atmospheric pressure. It may be conveniently visualized as the 'surface' of the subsurface materials that are saturated with groundwater in a given vicinity. However, saturated conditions may extend above the water table as surface tension holds water in some pores below atmospheric pressure.[1] Individual points on the water table are typically measured as the elevation that the water rises to in a well screened in the shallow groundwater.The groundwater may be from infiltrating precipitation or from groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. At increasing depths water fills in more of the pore spaces in the soils, until the zone of saturation is reached. In permeable or porous materials, such as sands and well fractured bedrock, the water table forms a relatively horizontal plane. Below the water table, in the phreatic zone, permeable units that yield groundwater are called aquifers. The ability of the aquifer to store groundwater is dependent on the primary and secondary porosity and permeability of the rock or soil. In soil that are less permeable, such as tight bedrock formations and historic lakebed deposits, the water table may be more difficult to define.The water table should not be confused with the water level in a deeper well. If a deeper aquifer has a lower permeable unit that confines the upward flow, then the water level in a well screened in this aquifer may rise to a level that is greater or less than the elevation of the actual water table. The elevation of the water in this deeper well is dependent upon the pressure in the deeper aquifer and is referred to as the potentiometric surface, not the water table.
Which water source contains more inorganic material surface water or ground water?
Surface Water
Does radon occur more in groundwater or surface water?
The groundwater contain more radon.
Is groundwater harder to clean up than surface water?
Yes, because its more complex to clean up groundwater than surface water.
Where does surface water travel?
Surface water flows downhill or seeps into the ground becoming groundwater. The natural flow of surface water is downhill or seaward. See the related link for more information.
Why do fish appear on the surface of the water before a storm?
Before a storm, there is very little dissolved oxygen in the water, so fish rise to the surface for oxygen,which is more plentiful near the surface.
Why does groundwater not need as many treatment stages as water taken from rivers or lakes?
Because surface water is exposed to more contaminants from the environment, than underground water.
What has more freshwater lakes and rivers or groundwater?
No, there is far more water in groundwater than is found in lakes and rivers. According to the United States Geological Survey groundwater accounts for 1.7% of all water on Earth. Although much of the water we use in our everyday comes from lakes and rivers, all together these sources account for approximately 0.014% of the water on Earth. Source: Gleick, P. H., 1996: Water resources. In Encyclopedia of Climate and Weather, ed. by S. H. Schneider, Oxford University Press, New York, vol. 2, pp.817-823
What has more freshwater lakes or groundwater?
Ground Water
How Many communities pump groundwater to irrigate crops and supply homes with water so how do you think over-pumping groundwater is related to the formations of sinkholes?
Many communities around the world rely on pumping groundwater for various purposes, including irrigation and water supply. Over-pumping groundwater can lead to the lowering of the water table, causing subsidence or sinking of the land surface. This subsidence increases the risk of sinkhole formation, as the ground becomes more prone to collapsing into underground cavities that were previously supported by groundwater.
What factor is lowered when more water is removed from groundwater than is returned to it?
The water table.
