What is the relationship between the depth to the water table and the depth that a well must be drilled?
The well depth must be greater than the depth to the water table.
What is the relationship between the depth of the water table and the depth that a well must be drilled?
Where the pump will be located in the well, and also how powerful the pump needs to be. Also the depth of the well is determined by how much water the well will deliver at a given depth. Some wells have to be drilled deeper to get the required water flow in a particular area.add. When drilling a well, the driller will determine the first point that water was encountered, and then drill somewhat lower yet. He is seeking a water layer that is in a gravel or porous strata. he will then flush some water INTO the strata, to determine its porosity, for the assumption is inflow ability = outflow ability.He will drill deeper than the first sign of water, for when other folk tap the same aquifer, the water table will lower.
Is well water surface water?
Surface water is from wells to about 30 ft deep. Drilled wells deeper than 30 ft are not surface water.
How can I know where to find an artesian well?
It's where the water table is higher than the well opening.
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.
What is the difference between a spring and a well?
A spring is when the water table reaches the Earths surface. A well is a man-made hole deeper than the water table.
What do you do if your well has no more water in it?
Possibly dig it a little deeper, the water table may have dropped. I would do that before I tried digging a new one.
What is the relationship between the depth to the water table and the depth that a well must be drilled?
The well depth must be greater than the depth to the water table.
You dig a well to find drinking water but you find that the well produces salty water as well as freah water Where in the well could expect to find salty water Fresh water?
The deeper the well the bigger chances to hit salty water. Fresh water is usually close to the surface as the ground water table varies with elevation.

Why do wells have to be built below the water table?
If the bottom of a well is above the water table, the well would be dry.
Where can people obtain groundwater by drilling a well A below the water table B above the water table C beside a water table?
above the water table
Is well water a type of surface water?
Well water is by definition from an underground aquifer, or water table.
How do you stop groundwater?
Less boring of tube-well and wells to extract more water than the seepage/charging of underground water to increase the water table.
