So the cause of this incident has not yet been attributed to the water supply, but Thames Water's dismissal of customer concerns here is very worrying.
> Thames Water rebuffed her requests to test her water. But after being contacted by the Guardian, Thames sent a technician to take samples from her tap on Monday.
Of things that should have been learned from the Camelford Water Incident by the water companies, the ability to rapidly deploy testing so as not to create an information void that cannot later be filled should be high up the list along with taking customer concerns seriously.
