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

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

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: Can groundwater be over a thousand years old?
No
