While drilling a water well, my drill bit hit something hard and nothing seemed to get through it. Do you have any suggestions?
Your drill bit is probably hitting rock, and while you can drill a well in rock, it will definitely slow down the process. Drilling through a large rock can slow the drilling down to half an inch per hour!
However, the real problem is not the big rocks, but the small watermelon-sized rocks. On rocks this big, the drill bit has nothing to bite into, so it rolls off. While it’s not impossible to get around rock when drilling a water well, it can be so time-consuming that it may be impractical to drill a well in a particular location.
You can always try drilling a well in another location on your property, but there is no guarantee that the rock formation you hit won’t extend under the entire property.
