What do we call the water-bearing layer underground?
Which conditions give water the best cleaning effect on the way to becoming groundwater?
Initially, water is driven underground by gravity. What is the main driver after a certain depth?
When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
