       | top off the swimming pool with water from well. After a few days
       | it turned a deep rusty brown. We obtained some sort of chemical
       | from the pool supply store which was supposed to make the iron
       | precipitate somehow. When that happened, the iron sank to the
       | bottom as a powder and the water turned a beautiful green color.
