In response to a question about how much bottled water the Wales Department bought over the past three years - which incidentally increased year on year - the Secretary of State of Wales Paul Murphy has implied that mains water (at least in London and Cardiff) is not drinkable unless it is filtered.
The implication came in his follow up response to justify his predecessor's increasing use of bottled water when he said his Department, "in line with Government initiatives on sustainable development, is exploring possibilities of installing filter taps to provide a drinking water tap in the kitchen at my London office.... My Cardiff office is fitted with a filter tap for drinking water."
Note that the filter will provide "drinking water" ergo, without a filter, the water is not drinkable. I wonder what the Drinking Water Inspectorate will make of that? Or is he seriously saying that the Wales Office on Whitehall only has a water supply from a tank and no mains feed piping into its kitchen?
