UPDATE: Unfortunately, my interview with the geologist fell through. She called while I was waiting for her to show up and explained that she had been in an area without cell phone towers and had been trying to call me to let me know. I will reschedule the interview. Thanks to all of you for the great input on this important topic.
Where does it come from? How does it get from there to here (i.e., my faucet)? What's a water table? A watershed? Ever hear of stream restoration? What's the difference between city water and well water and why the difference in taste? If you live in the country and have a well, does the water you use for watering lawns and gardens trickle back down through the earth and back into the water table? If so, why should those with well water worry about water conservation?
If you have a natural pond on your property that's been there for years, who really owns it? Is it considered a natural wetland? Why are swamps/wetlands protected in some areas, aren't they just mud pits and mosquito breeding grounds? How much water is used by gardeners and farmers? Who's responsible for water pollution from chemical runoff? What are you telling someone when you say: "It flows downstream"? How often should you have your water tested if you drink well water?
These are questions that I hope will be answered after I research my article "Water, water. Everywhere?" One of my sources is a geologist with Stream Restoration Incorporated and The Slippery Rock Watershed Coalition, I'll be interviewing her for the article.
