2: Can groundwater be over a thousand years old?
Yes
3: Why do people favour groundwater to surface water sources?
Access to surface water is often limited for many due to land ownership

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

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

Surface water source

5: How is a rising sea level a problem for coastal communities?
Because of saltwater intrusion into the coastal aquifers
5: How is a rising sea level a problem for coastal communities?
It isn't - as long as the aquifer is healthy, there will always be enough pressure to hold back the seawater
5: How is a rising sea level a problem for coastal communities?
It is actually a positive, because there will be greater pressure in wells further inland
6: Initially, water is driven underground by gravity. What is the main driver after a certain depth?
The main driver becomes pressure
6: Initially, water is driven underground by gravity. What is the main driver after a certain depth?
The main driver is still gravity
