Prior to the launch, an article in "The Grocer" trade magazine had stated that the source of the Dasani brand water was treated tap water from Sidcup, a suburban area on the outskirts of London. By early March 2004, the mainstream press had picked up the story and it became widely reported that Sidcup tap water, after being processed was being sold under the Dasani brand name in the UK. Although Coca-Cola never implied that the water was being sourced from a spring or other natural sources, they marketed it as being especially "pure". This led the Food Standards Agency (FSA) to request Hillingdon trading standards officers to launch an investigation into whether the claim was accurate.
