Answer to Question 1

Answer: Sand, because sandstone has been compacted and has cement lining part (or all) of the pore spaces.

Answer to Question 2

Answer: Reduce the amount of water taken from that well. Drill a new well further inland in a different aquifer. Inject wastewater into the subsurface to keep the saltwater below the level of the freshwater.
