Default Chlorine - how much is too much?

My water report indicates that I've got up to 1.4 ppm chlorine. Doesn't seem like much, but how much is too much?

As far as I know, any chlorine is too much. Good news is that if its chlorine and not chloramine, it should boil out. If you aren't getting plastic/bandaid flavors, its safe to assume this is the case. If you are, Campden tablets are probably the easiest and cheapest way to treat water with chlorine and chloramine.

+1 to this; a single crushed tablet will treat up to 20 gallons.

Drinking water filters work too but take forever if you don't have a faucet connection.

Chlorophenols have taste thresholds in the parts per billion.

Chlorine will go away if you leave the water sitting in an uncovered vessel overnight. You can speed it up by mixing a half tab of campden in.
