RE: Pour concrete on high ground water level location
Over-excavate and place good granular material, such as crushed stone, in the bottom of the excavation so that the concrete will not be placed on "mud".
Leave the top of this stone 3 inches lower than specified to compensate or the likely hood that the first concrete placed in the excavation will be contaminated by soil.
Keep the excavation pumped out with diaphragm pumps (mud-hogs) before and during concrete placement.
After the concrete has been placed, discontinue pumping and cure the concrete as usual.

Many times, even if the water table is high and the soil is sandy, the steady state inflow of groundwater into an excavation is manageable with pumps alone.

It depends on what you're going to build there as well.
