Q: Is climate change a significant problem for our groundwater?
A: No
Q: Is climate change a significant problem for our groundwater?
A: Yes
Q: Is climate change a significant problem for our groundwater?
A: We won't know for 40 to 50 years
Q: What do we call the water-bearing layer underground?
A: An aquifer
Q: What do we call the water-bearing layer underground?
A: A water tank
Q: What do we call the water-bearing layer underground?
A: A well
Q: Why do people favour groundwater to surface water sources?
A: Access to surface water is often limited for many due to land ownership
Q: Why do people favour groundwater to surface water sources?
A: They don't - lakes and rivers provide a much more reliable supply
Q: Why do people favour groundwater to surface water sources?
A: The cleaning effect from filtration through the subsurface makes groundwater much safer

A: Slow travel time through the subsurface
Q: Which conditions give water the best cleaning effect on the way to becoming groundwater?
A: There is no cleaning effect through the subsurface
