Can you spread the load on an aquifer by extracting from more wells distributed over a wider area?
What do we call the visible area from which the aquifer gets new water over time?
When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
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?
How is a rising sea level a problem for coastal communities?

Q: Can you spread the load on an aquifer by extracting from more wells distributed over a wider area?
A: Yes
Q: Can you spread the load on an aquifer by extracting from more wells distributed over a wider area?
A: No
Q: What do we call the visible area from which the aquifer gets new water over time?
A: Surface water source
Q: What do we call the visible area from which the aquifer gets new water over time?
A: The recharge area
Q: What do we call the visible area from which the aquifer gets new water over time?
A: The watershed
Q: When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
A: Pollutants in the water
Q: When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
A: Nothing - this process happens on the surface
Q: When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
A: Pure water and CO2
Q: 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?
A: 4 to 5 years
Q: 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?
A: Over a thousand years
Q: 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?
A: 40 to 50 years
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
Q: The rainwater which becomes new groundwater is called what?
A: Discharge
Q: The rainwater which becomes new groundwater is called what?
A: Replenish
Q: The rainwater which becomes new groundwater is called what?
A: Recharge
