I have a very nice looking stone-walled hand-dug well on my property which hasn't been used in many years. It is the old -fashioned kind, like the kind people would drop buckets into. There is still water there and a spring and creek not more than 60 feet away on either side. Problem is that it has been uncovered all these years. The water surface has a sheen to it, oily sort of. It grosses me out. The heirs of this property have told me the water always tasted muddy from that well (never were any filters on it). My first inclination was to fill it up. But it would be a shame as it is such a pretty well and I could use it to water the livestock (or irrigate if the water tests less than drinkable. So, my questions are, if the water test comes back halfway decent, can the well be cleaned up? Do companies do that sort of thing? All of the tubing looks broken so I would have the expense of repairs, cleaning, and a hand pump. Would be worth it for decent water if the cost is less than digging a new well. This would not be the well providing water to my house btw.
