How is a rising sea level a problem for coastal communities?
What do we call the visible area from which the aquifer gets new water over time?
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?

Q: How is a rising sea level a problem for coastal communities?
A: Because of saltwater intrusion into the coastal aquifers
Q: How is a rising sea level a problem for coastal communities?
A: It isn't - as long as the aquifer is healthy, there will always be enough pressure to hold back the seawater
Q: How is a rising sea level a problem for coastal communities?
A: It is actually a positive, because there will be greater pressure in wells further inland
