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: Can iron be precipitated from water flowing down 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

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
