I checked the GVRD website www.gvrd.bc.ca and they mention nothing about chloramine only that they use Ozone as a primary disifectant and chlorine as a secondary disinfectant.

from the link you posted
"Secondary Disinfection
As water flows through the distribution system, the disinfectant used at the primary stage gradually breaks down. This creates the potential for bacteria to grow in the water. Secondary disinfection with chlorine is used to continue safe-guarding the water as it travels to homes, businesses, and industries in the Lower Mainland. Ozone cannot be used as a secondary disinfectant because it breaks down too quickly."

dollers to donuts I will bet that there chlorine addition is in the form of Chloramine as chlorine breaks down to fast. Oazone is only a new (sence 1998) primary disafenctant.
