4: What happens if groundwater is depleted too fast?
The land subsides and a shallow lake forms

4: What happens if groundwater is depleted too fast?
The land subsides and dries out
4: What happens if groundwater is depleted too fast?
Water pressure drops, but in principle the aquifer is always there

5: Why do people favour groundwater to surface water sources?
Access to surface water is often limited for many due to land ownership

5: Why do people favour groundwater to surface water sources?
They don't - lakes and rivers provide a much more reliable supply

5: Why do people favour groundwater to surface water sources?
The cleaning effect from filtration through the subsurface makes groundwater much safer
