" Oh no,there's something wrong with the water"

Residents of parts of Lancashire on the 6/8/15 informed that they have to boil their drinking water until further notice as a parasite has entered the water supply and the water is unsafe to drink, today is the 11/8/15 and the warning is still in place although suppliers are hopeful water will be OK very shortly.
(Note the above picture is not the actual water supply mentioned but is from the local gardens where a colour( or color)has been added to a fountains supply, not sure of the reasons why).
