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.
Further, the amount of water contributed to streams from artesian aquifers in an arid region is so small as to be immeasurable. In the southwestern coastal basins of California, for instance, some groundwater from artesian aquifers is discharged into the Pacific Ocean below sea level.
