COMMISSION REGULATION (EU) No 115/2010  
of 9 February 2010  
laying down the conditions for use of activated alumina for the removal of fluoride from natural 
mineral waters and spring waters  
(Text with EEA relevance)  
THE EUROPEAN COMMISSION,  
Having regard to the Treaty on the Functioning of the European 
Union,  
Having regard to Directive 2009/54/EC of the European 
Parliament and of the Council of 18 June 2009 (  1 ), on the 
exploitation and marketing of natural mineral waters, and in 
particular Article 4(1)(c) and Article 12 (d) thereof,  
Having regard to the opinion of the European Food Safety 
Authority,  
Whereas:  
(1) Commission Directive 2003/40/EC of 16 May 2003 
establishing the list, concentration limits and labelling 
requirements for the constituents of natural mineral 
waters and the conditions for using ozone-enriched air 
for the treatment of natural mineral waters and spring 
waters (  2 ) sets a maximum limit for fluoride in natural 
mineral waters. As regards spring water, such a limit is 
fixed by Council Directive 98/83/EC of 3 November 
1998 on the quality of water intended for human 
consumption (  3 ). 
(2) To allow operators to comply with those Directives, a 
treatment to remove fluoride from natural mineral waters 
and spring waters by using activated alumina (hereinafter 
‘the fluoride removal treatment’) should be authorised.  
(3) The fluoride removal treatment should not add residues 
to the treated water at concentrations which may pose a 
risk to public health.  
(4) The fluoride removal treatment should be notified to the 
competent authorities to allow those authorities to 
exercise the controls necessary to ensure correct appli ­
cation of the treatment.  
(5) The use of a fluoride removal treatment should be 
indicated on the label of treated water.  
(6) The measures provided for in this Regulation are in 
accordance with the opinion of the Standing 
Committee on the Food Chain and Animal Health and neither the European Parliament nor the Council has 
opposed them,  
HAS ADOPTED THIS REGULATION:  
Article 1  
1. The treatment of natural mineral waters and spring waters 
with activated alumina in order to remove fluoride, hereinafter 
‘the fluoride removal treatment’, shall be allowed.  
Natural mineral waters and spring waters together are referred 
to hereinafter as ‘water’.  
2. The fluoride removal treatment shall be performed in 
accordance with the technical requirements as set out in the 
Annex.  
Article 2  
The release of residues into the water as a result of the fluoride 
removal treatment shall be as low as technically feasible 
according to the best practices and shall not pose a risk to 
public health. To ensure this, the operator shall implement 
and monitor the critical processing steps set in the Annex.  
Article 3  
1. The application of a fluoride removal treatment shall be 
notified to the competent authorities at least three months prior 
to use.  
2. With the notification the operator shall communicate to 
the competent authorities relevant information, documentation 
and analytical results on the treatment which show that it 
complies with the Annex.  
Article 4  
The label on water which has been the subject of a fluoride 
removal treatment shall include, in proximity to the statement 
of the analytical composition, the indication ‘water subjected to 
an authorised adsorption technique’.  
Article 5  
This Regulation shall enter into force on the 20th day following 
its publication in the  Official Journal of the European Union .EN 10.2.2010 Official Journal of the European Union L 37/13

( 2 ) OJ L 126, 22.5.2003, p. 34.  
( 3 ) OJ L 330, 5.12.1998, p. 32.Products which were placed on the market by 10 August 2010 and which do not comply with Article 4, 
may continue to be marketed until 10 August 2011.  
This Regulation shall be binding in its entirety and directly applicable in all Member States.

Technical requirements for the use of activated alumina for the removal of fluoride from natural mineral waters 
and spring waters  
The following critical processing steps shall be implemented and monitored appropriately:  
1. Before the activated alumina is used for the treatment of water it shall be subjected to an initialisation procedure which 
includes the use of acidic or alkaline chemicals to remove any residues and a backwash treatment to remove fine 
particles.  
2. A regeneration procedure shall be applied at intervals ranging from one to four weeks depending on the water quality 
and throughput. It shall include the use of appropriate chemicals to remove the adsorbed ions in order to restore the 
adsorption capacity of the activated alumina, and to remove any possibly formed biofilms. This procedure shall be 
done in the following three stages:  
— Treatment with sodium hydroxide to remove fluoride ions and replace them with hydroxide ions.  
— Treatment with an acid to remove residual sodium hydroxide and activate the medium.  
— Rinsing with drinking or demineralised water and conditioning with the water as the final step in order to ensure 
that the filter has no impact on the overall mineral content of the treated water.  
3. The chemicals and reagents used for the initialisation and regeneration procedures shall comply with the relevant 
European standards (  1 ) or applicable national standards relating to the purity of the chemical reagents used for 
treatment of water intended for human consumption.  
4. The activated alumina shall comply with the European standard for leaching tests (EN 12902) (  2 ) to ensure that no 
residues are released into the water resulting in concentrations exceeding the limits set in Directive 2003/40/EC or in 
the absence of limits in that Directive, the limits set in Directive 98/83/EC or in applicable national legislation. The 
total amount of aluminium ions in the treated water as it results after the release of aluminium, the main component 
of activated alumina, shall not exceed 200microg/L, as established in Directive 98/83/EC. This amount shall be 
checked regularly in accordance with the Council Directive.  
5. The processing steps shall be subject to good manufacturing practices and HACCP principles set out in Regulation (EC) 
No 852/2004 of the European Parliament and of the Council on food hygiene (  3 ). 
6. The operator shall establish a monitoring programme in order to ensure the proper functioning of the processing steps 
in particular as regards the maintenance of the essential characteristics of the water and its fluoride content.EN 10.2.2010 Official Journal of the European Union L 37/15
