The two correct answers regarding the possible consequences of a lower water table are:
1. **Saltwater intrusion**: Lowering the water table can allow saltwater from oceans or seas to move into freshwater aquifers, especially in coastal areas.
2. **Land subsidence**: When water is pumped out of the ground and the water table drops, the support that water provides to the soil can decrease, leading to sinking or settling of the land surface.
So the correct answers are **saltwater intrusion** and **land subsidence**.
