Q: Is climate change a significant problem for our groundwater?
A: We won't know for 40 to 50 years
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
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
