Drilling a water well, USGS Water Science School

Picture of a well being drilled Picture of a well being drilled I like playing in the dirt as much as the next guy, but I'm not upset that I've never had the honor of standing in muck helping to drill a water well. Now, not all wells are drilled in an area this wet (most are drilled in rock). Notice the big screw used to do the drilling. In the left-side picture, the driller is adding another length of pipe to extend the length of the drilling screw. This drilling apparatus only works when drilling shallow wells in soft soil. And drilling in soft soil is much quicker and easier than drilling through solid granite, where a rock-eating drill bit must be used.

Of course, maybe these guys like their job -- how many adults get paid to work in the mud?
