1: What do we call the visible area from which the aquifer gets new water over time?
2: When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
Pollutants in the water

2: When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
Nothing - this process happens on the surface

2: When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
Pure water and CO2
3: How is a rising sea level a problem for coastal communities?
Because of saltwater intrusion into the coastal aquifers
3: 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
3: 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
4: Which conditions give water the best cleaning effect on the way to becoming groundwater?
Fast travel time through the subsurface

4: Which conditions give water the best cleaning effect on the way to becoming groundwater?
Slow travel time through the subsurface
4: Which conditions give water the best cleaning effect on the way to becoming groundwater?
There is no cleaning effect through the subsurface

5: Why do people favour groundwater to surface water sources?
Access to surface water is often limited for many due to land ownership
You can find the answer here >
5: Why do people favour groundwater to surface water sources?
They don't - lakes and rivers provide a much more reliable supply
You can find the answer here >
5: Why do people favour groundwater to surface water sources?
The cleaning effect from filtration through the subsurface makes groundwater much safer
6: What happens if groundwater is depleted too fast?
The land subsides and a shallow lake forms
You can find the answer here >
6: What happens if groundwater is depleted too fast?
The land subsides and dries out
6: What happens if groundwater is depleted too fast?
Water pressure drops, but in principle the aquifer is always there
