I grew up in the coal fields, no one had water that was pumped from a lake in our area back then, a few homes in the area had drilled wells in their yard, my grandmother had a well in her yard, it had good water but didn't produce enough to do the washing, she did the clothes washing on Saturday, and my job was to carry the wash water from an old mine opening about a thousand feet from our house, the water that ran from that old mine ran year round, it was crystal clear, yet it left an orange color on the bottom of the stream, I would get thirsty from carrying the wash water or playing in the area and drink from the old mine, it was clear and cold but had a bitter taste, everyone from the area always called it sulphur water, over the years of my youth I would think, I've drank many gallons of the sulphur water, as long as you are drinking it you can't taste the sulphur, but the after taste after you drink your fill is really bitter,
