Prior to the launch, an article in The Grocer trade magazine had mentioned that the source of the Dasani brand water was in fact treated tap water from Sidcup, a suburban development in London. By early March 2004, the mainstream press had picked up the story[8] and it became widely reported that Sidcup tap water, after being processed by reverse osmosis, had been remineralized, bottled and sold under the Dasani brand name in the UK.[4] Although Coca-Cola never implied that the water was being sourced from a spring or other natural source, they marketed it as being especially "pure". This led the Food Standards Agency to request Hillingdon trading standards officers to launch an investigation into whether the claim was accurate.[9]

Richard May, Chief Publicity Officer of Dasani, was said to be disappointed that the water had not been more successful.

The media made mocking parallels with a 1992 episode of the well-known BBC sitcom Only Fools and Horses, in which protagonist Del Boy attempts to pass off local tap water as bottled "Peckham Spring".[4] Del's scheme fails when he pollutes the local reservoir, causing the bottled water to glow yellow.
