The sea level changed in the geological past for example Quaternary sea level change. Do the chemical composition of groundwater change in glacial and interglacial period?
If mixing happened it would affect the quality for sure, but fresh water always rest over saline water due to difference in density and mixing need time. When fresh water and saltwater meet in an estuary for example, they do not always mix very fast. The problem with sea level change is mostly the sea water intrusion which can go for several kilometers affecting groundwater aquifers. Sea water intrusion can also increase if there are decrease in the fresh water discharge from rivers to the sea.
I completely agree with Professor Dr. Yehia H. Dawood. Sea water intrusion can be promoted by the decease in discharge of freshwater from the. rivers.

It does. Kindly go through this link to understand the mechanism.

Yes. In Florida, USA, due to destruction of wetlands there have been issues with sea water contaminating potable water as well as septic tank water getting into water tables. They are now working on reversing the trend by trying to restore wetlands to some extent as well as providing connectivity among bodies of fresh water.
Dear Sudip,
The following articles by [Ketabchi et al., 2016] on the matter of Sea-Level Rise on SWI might be useful for you:
1) Article Sea-Level Rise Impact on Fresh Groundwater Lens in Two-Layer...
2) Article Sea-level rise impacts on seawater intrusion in coastal aqui...
Hope you might find it useful.
Sincerely,
Behshad
