The EUSR National Water Hygiene 'Blue Card' is the UK water industry's standard hygiene certification, required for access to clean-water (potable) sites and for work on drinking-water systems. After a half-day EUSR-approved course, candidates sit a 25-question multiple-choice assessment and complete a mandatory health pre-screening. The course covers four areas: the importance of water, water as a carrier of disease, potential contamination and its consequences, and preventing contamination. Supplying water unfit for human consumption is a criminal offence under the Water Industry Act 1991, and the Water Supply (Water Fittings) Regulations 1999 set the legal requirements for preventing contamination. The card is valid for 3 years with no shortcut refresher. This 100-question bank gives original revision practice modelled on the four scheme areas.

About the EUSR Water Hygiene Exam
The EUSR National Water Hygiene scheme, widely known as the 'Blue Card', is the UK water industry's standard hygiene certification for anyone who needs access to clean-water (potable) operational sites or who works on drinking-water systems, whether or not they contact the water itself. Introduced in 2006, it replaced the many separate water-company hygiene schemes so that a worker holds a single recognised card. Training is delivered by EUSR-approved providers as a half-day classroom course or e-learning, and is assessed by a multiple-choice test of 25 questions plus a mandatory health pre-screening. The course covers the importance of clean water, water as a carrier of disease, how contamination occurs and its consequences, and how to prevent contamination through good hygiene, hygienic working methods, approved materials and the Water Supply (Water Fittings) Regulations 1999. On passing, the candidate is issued an EUSR National Water Hygiene card (now usually a virtual card) valid for 3 years.
Assessment
A single multiple-choice question paper of 25 questions covering four areas: the importance of water; water as a carrier of disease; potential contamination and its consequences; and preventing contamination. A mandatory health pre-screening declaration is completed alongside the assessment.
Time Limit
Short multiple-choice assessment sat at the end of a half-day course; e-learning delivery typically allows about 30 minutes for revision and the online test.
Passing Score
Candidates must pass the 25-question assessment to the EUSR standard applied by the approved provider and complete the health pre-screening to be issued the National Water Hygiene card.
Exam Fee
Course and assessment fees are set by EUSR-approved providers, typically about £100 to £150 plus VAT for the half-day course including EUSR registration; there is no separate EUSR examination fee. (Energy & Utility Skills Register (EUSR), delivered through EUSR-approved training providers)
EUSR Water Hygiene Exam Content Outline
The importance of water
Why clean and safe drinking water is essential, treating water as a food, the individual worker's responsibility for protecting public health, the role of water companies and regulators, and that supplying water unfit for human consumption is a criminal offence under the Water Industry Act 1991.
Water as a carrier of disease
How drinking water can carry pathogens and cause illness: Cryptosporidium, Giardia, E. coli, Legionella and viruses; the diseases linked to contaminated water such as gastroenteritis, typhoid, dysentery and hepatitis A; the faecal-oral route; and the serious public-health consequences of a contamination incident.
Potential contamination and its consequences
The three contamination types (physical, chemical and microbiological); how contamination enters through backflow, back-siphonage and cross-connection; fluid risk categories; and the causes and consequences of contamination at water treatment works, in service reservoirs and storage, and across the distribution network.
Preventing contamination
Personal hygiene and health: hand hygiene, reporting illness (including stomach upsets and hepatitis A), exclusion periods, and the health pre-screening; hygienic working methods near potable water; use of approved materials and fittings; keeping tools and equipment clean; and Water Supply (Water Fittings) Regulations 1999 duties.

Frequently Asked Questions
What is the EUSR National Water Hygiene 'Blue Card'?
It is the UK water industry's standard hygiene certification, run by the Energy & Utility Skills Register. The card is required for access to clean-water (potable) operational sites and for work on drinking-water systems, whether or not you contact the water.
How many questions are on the National Water Hygiene assessment?
The assessment is a multiple-choice test of 25 questions, taken after the EUSR-approved training course. Candidates must also complete a mandatory health pre-screening declaration to be issued the card.
How long is the National Water Hygiene card valid?
The card is valid for 3 years. There is no refresher or shortcut version, so the full course and assessment must be retaken to renew the certification.
What does the course cover?
Four areas: the importance of water; water as a carrier of disease; potential contamination and its consequences; and preventing contamination through good hygiene, hygienic working, approved materials and the Water Supply (Water Fittings) Regulations 1999.
Why is a health pre-screening required?
Workers near potable water can pass on waterborne illness, so anyone with potential contact with treated water must declare their health status. Those with stomach upsets, diarrhoea or certain infections such as hepatitis A must report them and may be excluded from water work.
Are these official EUSR practice questions?
No. These are original OpenExamPrep questions modelled on the four scheme areas. Sit the real 25-question assessment through an EUSR-approved training provider to obtain your Blue Card.
