Virginia Subtractions From Income. Before you can calculate your tax amount, you must first determine your Virginia taxable income (VTI), upon which your tax is based. Federal adjusted gross income (FAGI) is the starting point for computing (VTI) on individual tax returns.
An artesian well is a pumpless water source that uses pipes to allow underground water that is under pressure to rise to the surface. This type of well seems to defy gravity because the pressure that builds up between layers of rock gets relieved when the water finds a path to the open air.
Discharge of artesian aquifers. Water that moves through artesian aquifers is discharged upward through areas of the overlying confining bed that are relatively permeable. Fault and fracture zones that penetrate the confining bed would also allow the water to escape upwards.n this case, the top of the aquifer supports a load of rock equal to about 520 lbs. per sq. in. (36.4 kg/cm2). A part of this load is supported by the sandstone aquifer and a part by the water, which is under artesian pressure and hence is pushing upward and downward against the confining beds.
