that's what's makes the 'purified water' claim so ironic.
So now the full scale of Coke's PR disaster is clear. It goes something like this: take Thames Water from the tap in your factory in Sidcup, Kent; put it through a purification process, call it "pure" and give it a mark-up from 0.03p to 95p per half litre; in the process, add a batch of calcium chloride, containing bromide, for "taste profile"; then pump ozone through it, oxidising the bromide - which is not a problem - into bromate - which is. Finally, dispatch to the shops bottles of water containing up to twice the legal limit for bromate (10 micrograms per litre).
The Drinking Water Inspectorate confirmed yesterday it had checked the Thames water supplied to the factory and found it free of bromate. Because it is unsafe at high levels, standards for bromate in tap water are strictly monitored.
Bromide is a naturally occurring trace chemical which has a sedative effect. It is said to have been added by the British army to soldiers' tea during the second world war to dampen down their lust. But when it is oxidised into bromate it becomes "a pretty nasty carcinogen", according to David Drury, one of the principal inspectors for the DWI.
