Depends on what's in the water table you've tapped into, as to whether or not is has sulphur, iron or calcium and other minerals.
When I built a house here at home in the mid 70s, we had three wells drilled on adjoining lots. First two had horrible water, so I had the guy keep going on my lot. Neighbors had iron/sulpher treatment systems in addition to a water softener. All I ever had was a water softener, different "vein" of water.
Our old place across the valley from camp was fed from a sulphur spring. Always enjoyed filling the water heater each year and turning it on.
Eventually everyone learned to clear out when I opened the kitchen faucets and fogged the place with that rotten egg smell, once the water was hot.
Current camp well is fed by a spring. No sulphur, but the water is very hard. With the current drought, not much water, either. Well is only about 120' deep. Next place up the road has a well several hundred feet deep and they have iron and other minerals in their water.
Some of the wells in the area are over 400 feet deep to get any water at all.
Ours was punched in 1980 by McLaughlin's in Westfield (Tioga Co.) and the son is still drilling wells. Just did one last deer season on the other side of the ridge from me. Heard that's another 400 footer?
Buddy that built a camp south of Galeton in the mid 80s, had Germania finish his well after Eichelberger's couldn't find water with their rotary rig back then. IIRC that well was over 400' deep when finished and was the third or fourth attempt at a well on his place.
