What do we call the visible area from which the aquifer gets new water over time?
Which conditions give water the best cleaning effect on the way to becoming groundwater?
When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
Initially, water is driven underground by gravity. What is the main driver after a certain depth?
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?
