@Laotionne - A good drinking water purification system can eliminate about anything, including chlorine. When I was a child, I spent a good portion of my summer vacations at my grandmother and grandfather's farm. There was this large well on the property, and the water for the house came from the well. However you could also drop a bucket into the well and pull up the water before it was pulled into the pipes by the pump.
The taste of the water you got from the bucket was significantly different from what you got from the faucets in the house. The reason for this was that the water was filtered after it was pulled into the pipes by the pump, but before it went into the house. The water that came directly from the well was terrible, but once it came out of the faucet the taste was really good.
My grandfather said the bad taste was partly because of all of the fertilizers and chemicals used for growing crops over the years. The chemicals had filtered into the ground water.
