The increase in groundwater under coastal airport can cause problems to infrastructures of the airport and can attract birds if ponds are created. Hence some management options are needed.
Well,
dewatering by battery wells or horizontal filter drain process at level you need.
Sincerely
I agree with Bayan but would add too that depending on the layout, it could be worth trying to intercept and divert groundwater up-gradient of the site by a system of interceptor trenches or French drains.
Thanks Bayan & George. The current situation doesn’t allow for trenches and the current wells have maximum yield that is less than 10% of recharge rate!
Is there any risk on superstructures settlements in the airport due to groundwater pumping?! Any guidance on this issue?
Subsidence from groundwater pumping depends on the location and thickness of fine-grained sediments. See this USGS website for more details:

By groundwater contamination management philosophy, preventing contaminant is better than remediation. For the proposed management of the groundwater system, lowering the water table will be a good option, particularly by well dewatering technique.
