##  [UK DEFRA Updates Regulations on Spring and Natural Mineral Water Quality, Testing, and Labelling Requirements](/consumer-industry-news/uk-defra-updates-regulations-on-spring-and-natural-mineral-water-quality-testing-and-labelling-requirements) 

April 9, 2026

On April 9, 2026, Department for Environment, Food and Rural Affairs (DEFRA) issued updated regulations governing the quality, monitoring, treatment, and labelling of spring water and natural mineral water in the United Kingdom. The regulation entered into force immediately upon publication and introduces more detailed technical and compliance requirements for operators.

1\. Requirements for Spring Water  
a. Water Quality Standards  
Spring water must comply with strict limits across chemical, microbiological, and radiological parameters, including:  
1.Chemical contaminants:  
Arsenic 10 g/L  
Cadmium 5 g/L  
Nickel 20 g/L  
Polycyclic aromatic hydrocarbons 0.1 g/L  
Vinyl chloride 0.5 g/L

2.Microbiological safety:  
Absence of enterococci  
Absence of Pseudomonas aeruginosa  
Absence of sulfite-reducing anaerobic spore-forming bacteria  
Radioactive substances:  
Radon 100 Bq/L  
Tritium 100 Bq/L

b. Treatment Controls  
Oxidation using oxygen-enriched air requires prior authorization from local authorities  
Treatment residues must remain within specified limits  
Any unintended disinfection effects are prohibited  
Activated alumina treatment is restricted to fluoride removal only and requires approval at least three months in advance.

c. Labelling Requirements  
The product must be labelled as spring water  
The source of extraction must be clearly indicated  
If a different geographical name is used:  
The source location font must be at least 1.5 larger than the product name  
If ozone-enriched air oxidation is used, it must be declared on the label.

2\. Requirements for Natural Mineral Water  
a. Monitoring and Testing Obligations

Operators must implement structured and periodic monitoring:  
Monthly: flow rate, dry residue (mineral content), conductivity  
Quarterly: anions and cations  
Monthly: naturally occurring chemical substances (e.g., arsenic ? 0.010 mg/L, lead ? 0.010 mg/L, nitrate ? 50 mg/L)  
Every 3 months: microbiological testing confirming absence of pathogens such as Escherichia coli, Pseudomonas aeruginosa, and enterococci

b. Permitted Processing Methods  
Only specific treatments are allowed:  
Filtration or decantation  
Removal or addition of carbon dioxide  
Oxidation using oxygen-enriched air  
Activated alumina treatment  
c. Labelling and Claims  
Product must be labelled natural mineral water  
Mandatory label information includes:  
Extraction site  
Mineral and chemical composition with content levels  
Fluoride warning requirement:  
If fluoride > 1.5 mg/L ? label must state:  
Contains more than 1.5 mg/L fluoride: not suitable for regular consumption by infants and children under 7 years of age.  
Optional nutrition claims permitted if criteria met, such as:  
Low mineral content (? 500 mg/L total dissolved solids)  
Contains calcium (e.g., calcium > 150 mg/L)  
Regulatory Impact

These updated rules strengthen consumer protection, transparency, and product traceability by:

Introducing clear contaminant limits  
Standardizing monitoring frequency  
Tightening processing controls  
Enhancing labelling clarity and risk communication, especially for sensitive groups (e.g., children and infants)  
The regulation ensures alignment with modern safety expectations while maintaining the distinct regulatory identity of spring water vs. natural mineral water categories.
