Water tests found excess fluoride
Too much fluoride was put into the water supply after a new dosing system at Severn Trent Water failed, the watchdog said.
The Drinking Water Inspectorate said a fault happened at the pumping station which supplies 29,000 homes between Bridgnorth and Wolverhampton last June. Two tests on treated water at the station failed, with one showing fluoride at twice the target level.

Severn Trent Water apologised but said the water had still been safe to drink.
The Drinking Water Inspectorate (DWI) said work to complete a new fluoride dosing pump and dose controller was completed at Dimmingsdale Borehole Plumping Station near Wolverhampton on 12 June 2008.
A routine sample on 1 July 2008 found treated water at the works contained 2mg of fluoride per litre of water - which is twice the target level, it said.
A further test two days later showed 1.86mg of fluoride.
'High standards'
The DWI was critical of Severn Trent Water (STW) who it said did not detect the problem for a month and then tested the supply going to the wrong homes.
The report recommended the firm reviewed its staff training and its awareness of drinking water quality standards.
STW said the elevated fluoride levels were short-lived and "did not pose a risk to health at any stage".
"While the water was still safe to drink, these samples and the way in which they arose fell short of the high standards we expect at Severn Trent," a spokesman said.
The firm said it had taken action in a number of areas to minimise the risk of it happening again, including strengthening its controls and procedures.

Brian Jackson comments...
Perhaps on the only way that such risks can actually be eliminated is by not introducing this toxic waste into the water supply in the first place.
How come it took Severn Trent a month to discover this toxic release of fluoride at twice the legal level.?
And also, how come they actually tested the wrong homes?
Its also a matter of concern that the news has only emerged now nearly a year later. As a result neither the Severn Trent Water Company nor the Drinking Water Inspectorate can be said to have treated this issue with alacrity or the degree of rigour one should expect.
People concerned about water quality in their area can request print outs of their local water supplies by Zones if they contact the Water Companies. This info should be in the public domain. Perhaps if the companies and the DWI are failing in their responsibilities we should shake them up a little.
