When digging the front frost wall trench there was some ground water seeping up. The soil is sandy and the excation guy said the water woulnt be a problem and the footing could be poured as that it would displace the water. I’m a little concerned about settlement. Anyone have experience with this ?

as long as the water seeped in, and did not flow, you should be ok.
(assuming the bottom is undisturbed or compacted)
If the water caused the sides of the trench to cave in, you would want to remove the loose fill before pouring the footer.
Remember that concrete does not dry, the chemical reaction involves water reacting with the other components to form a chemical bond. excess water helps as long as it is not agitated to the degree it modifies the mix.
Ok thanks very much. Its a small trickle for the most part. We were thinking we were going to line bottom of trench with 6 inches of stone, then put footers on top to allow water to run under the stone.
