No. I'd bet the amount of chlorine/chloramine in your water is directly link to a number of factors.
For example - if your water comes from a tank, and its been sitting in the tank for a day or two, the chlorine will have had a chance to disapate.
If your water comes from the mains, and you haven't had much rain recently, the resevior could be low and the amount of chlorine may not be as disolved as normal.
Finally, remember that chlorine is a gas at room temperature. In order for it to be mixed with the water it is added under pressure. It will come out of the water if it is allowed time to exchange via difussion (leaving it sitting in a bucket) of if the engery required to evap is less than the energy holding it in. This can best be seen by partly covering your tap (faucet!) with your finger. Squirt the water down into the sink, and sniff!!
