Can you spread the load on an aquifer by extracting from more wells distributed over a wider area?
Is climate change a significant problem for our groundwater?
What do we call the water-bearing layer underground?
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?
