The two correct answers regarding the consequences of a lower water table are:

  1. Saltwater intrusion - As the water table lowers, particularly in coastal areas, saltwater can intrude into freshwater aquifers, leading to contamination of drinking water sources.

  2. Land subsidence - Lowering of the water table can cause the ground to sink, leading to land subsidence, which can damage infrastructure and alter the landscape.

So, the correct responses are:

  • Saltwater intrusion
  • Land subsidence
