Dear Drinking Water Inspectorate,
Do you have any data for the drinking water supplies in the UK that contain Legionella bacteria. I am aware that the culture method used has a limit of detection. This data and the low level (non culturable level) contamination is of great interest.
Thank you for your e-mail. Your enquiry has been received by the Drinking
Water Inspectorate and we aim to respond within 5 working days.

Dear DWI Enquiries (DWI),
Following my request sent to you 1st December 2013 "Do you have any data for the drinking water supplies in the UK that contain Legionella bacteria. I am aware that the culture method used has a limit of detection. This data and the low level (non culturable level) contamination is of great interest", I have had no response from yourselves regarding the matter and as such by not receiving a reply by 3rd January 2014 I believe you are in contravention of the freedom of information act.
I await your reply within the nevt 7 days before taking further action.
Dear Mr Mount,
Please accept our apologies, having checked our records it appears your initial enquiry did not reach us.
In response to your enquiry, regarding data on Legionella in drinking water, I can confirm that the Drinking Water Inspectorate does not hold any data on drinking water supplies containing Legionella. Drinking water supplies are not required to be routinely tested for Legionella as drinking water supplies entering premises from water mains are not at a temperature that supports the growth of Legionella. Legionella is associated with warm water and there is information on its control on the HSE website at http://www.hse.gov.uk/legionnaires/
