Dear Mr Jones 
 
Re: Certification of chloramine 
 
Thank you for your Freedom of Information request dated 23 November 2009 
regarding information held by the Health Protection Agency (HPA) on the certification 
of chloramine. Under section 1 (1) (a) of the Act I can confirm that we do not hold the 
information you have requested. 
 
In accordance with our section 16 duty to provide advice and assistance I would 
suggest that you contact the British Standards Institution (http://www.bsigroup.com/) 
regarding chlorine BS EN 937:1999, and ammonium sulphate BS EN 12123:1999. 
 
You may also find more information in Annex 2 of the Drinking Water Inspectorate’s 
list of approved products for use in Public Water Supply in the United Kingdom 
(http://www.dwi.gov.uk/31/pdf/soslist06.pdf) 
 
I hope you have found this information useful, however, if you are dissatisfied with 
this response and would like a copy of the HPA complaints procedure then please 
contact Mr George Stafford, Complaints Manager at: Health Protection Agency, 61 
Colindale Avenue, London NW9 5EQ. 
 
Please note that you have the right to an independent review by the Information 
Commissioner’s Office if a complaint cannot be resolved through the HPA complaints 
procedure. The Information Commissioner’s Office can be contacted by writing to 
Information Commissioner’s Office, Wycliffe House, Water Lane, Wilmslow, Cheshire 
SK9 5AF. 
 
Please contact me if you require any further information or assistance. 
 
Yours sincerely 
Leigh Kelly 
Freedom of Information Officer 
Health Protection Agency
