The two correct answers regarding the possible consequences of a lower water table are:
1. **Saltwater intrusion** - As the water table lowers, it can lead to saltwater moving into freshwater aquifers, especially in coastal areas, which can contaminate the freshwater supply.
2. **Land subsidence** - Lowering the water table can cause the ground above to sink or settle, a phenomenon known as land subsidence, as the support provided by the water in the soil is removed.
So, the correct responses are **saltwater intrusion** and **land subsidence**.
