Drilling a well is loud. It sounds like a motorcycle having a fight with a jackhammer. Your neighbors will hate you for a day or two.
Sometimes, you hit air. Yes, air. Drillers call it a "dry hole." You pay for it anyway. It’s like ordering pizza and getting an empty box.
There’s a thing called “artesian pressure.” If you hit it, water might shoot out of the ground like a geyser. That’s cool—but also a problem. You’ll need a cap.
Oh, and smelly water. Some wells taste like rotten eggs. That’s sulfur. You can fix it with a filter, but it’s a reminder that the earth is weird.
