Should I care if I have tannin in my water?
A lab test of the water at my cottage indicates I have 0.6 mg/L tannic acid in my water. The lab tech seemed a little surprised. The norm appears to be none or a lot. I am guessing I have something in between.
Should I care? How much is too much? Dose this level of tannin gum up water softeners or iron filters? I ask because I am renewing my water conditioning equipment at my cottage and would like to know if tannin is anything other than an aesthetic issue.
My well is over 50 years old, made of round clay tiles and close to a river loaded with tannin. Not a big surprise that some tannin makes it into the well. My coliform was negative, so I guess the water is safe.
I want to avoid a new well like to couple of my neighbors have. They’re deep, 380 – 400 feet, the water taste salty, it stinks like rotten eggs, and turns everything black.
Opps, I am losing my dsl connection, time to fly, thanks
