The two correct answers regarding the possible consequences of a lower water table are:
1. **Land subsidence** - When water is pumped out of the ground, the support that the water provided to the soil can decrease, leading to the sinking or settling of the land above.
2. **Saltwater intrusion** - Lowering the water table can allow saltwater from oceans or other bodies of saltwater to move into freshwater aquifers, leading to contamination of drinking water sources.
So, the correct responses are **land subsidence** and **saltwater intrusion**.
