The water on my property is the same way. Turn on the hose and plug your nose. My pig drank it for a year with no ill-effects, as did my chickens. I even took a few swallows during the summer when I was working outside and forgot to bring a canteen. Didn't kill me, obviously. Didn't even make me sick. Now, whether or not I get cancer in 20 years, that's yet to be seen.
