CHLORAMINE REDUX

The White Rock public has been assured that White Rock government will have a plan in place to deal with any piped water that ends in the general environment whether it is being disinfected using chlorine or chloramine.

The recent Five Corners fire saw a lot of firefighting water make its way to the ocean via surface and pipe. Was any of it treated as per the assurances given by city hall ? No one will tell us. But we can guess that the answer is NO.

The fact that spills in the aquatic environment are usually not planned for was the main reason the Regional Council of Engineers voted overwhelmingly against chloramine in the Metro water supply back in the 1990s.

All disinfectants including chlorine still require a REALISTIC plan to deal with this kind of introduction of piped water into the environment and to date , White Rock residents have yet to see it.

Do not Consume

White Rock was slow to implement a comprehensive backflow protection policy.

Nonetheless it’s now in place. The idea is to keep toxic chemicals from various types of systems including hot water heating systems from entering the drinking supply when there are large pressure drops, thus increasing public protection. Then there are situations like typical exterior hose valves that are considered moderately risky — prohibited in new construction but common in older buildings.

The reason mandated backflow and cross-connection technology should be tested annually is to find devices that need maintenance, repair or replacement .

The chances of a device being out of order (and dangerous) increase dramatically during major pressure regime fluctuations like the one caused by the recent large firefighting effort. Since boiling water does nothing to mitigate toxic chemicals in the water supply—- should this type of situation arise,   it seems reasonable to ask people to take precautions by ceasing to drink tap water, not just boil it.
