How would you rate this course?
1: Why do people favour groundwater to surface water sources?
Access to surface water is often limited for many due to land ownership

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

1: Why do people favour groundwater to surface water sources?
The cleaning effect from filtration through the subsurface makes groundwater much safer
2: Can technology help us find groundwater without digging bore holes?
No

3: When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
Pure water and CO2
4: Initially, water is driven underground by gravity. What is the main driver after a certain depth?
The main driver becomes pressure
4: Initially, water is driven underground by gravity. What is the main driver after a certain depth?
The main driver is still gravity

4: Initially, water is driven underground by gravity. What is the main driver after a certain depth?
Both pressure and gravity, depending on conditions

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: Can groundwater be over a thousand years old?
No
