I checked the Woodstock regions report, it appears only free chlorine is used there.
It's site was much clearer about water parameters.
So free chlorine will off gas quickly, and carbon will be very effective.
Water is moderately hard with a great buffering capacity ( alkalinity over 200ppm).
Nitrate was a little high in some areas, up to 6 ppm, so those wells must be in much more agricultural area, where fertilization is in high use.
Depending on what filtration you use, if a sump, running a drip direct to the sump (instead of the tank) and into an area where the water is agitated might be very effective enough with off gasing the small amount of chlorine residual.
