Achieved badges:
How would you rate this course?
1: How is a rising sea level a problem for coastal communities?
Because of saltwater intrusion into the coastal aquifers
1: 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
1: 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
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: 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
4: In the example given in the course, how many years will it take potentially for the effects of surface pollution to show up in drinking water?
4 to 5 years
4: In the example given in the course, how many years will it take potentially for the effects of surface pollution to show up in drinking water?
Over a thousand years
