1: Can iron be precipitated from water flowing down through the subsurface?
No

2: How is a rising sea level a problem for coastal communities?
Because of saltwater intrusion into the coastal aquifers
2: 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
2: 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
3: The rainwater which becomes new groundwater is called what?
Discharge

4: When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
Pure water and CO2
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
6: Which conditions give water the best cleaning effect on the way to becoming groundwater?
Fast travel time through the subsurface

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