Common water contaminants worldwide

Know what could be in your water and the health risks they carry — whether you are in the UK, USA, Asia, Africa or anywhere else.

🔩

Lead

Enters water from old lead pipes and solder. Even low levels cause serious neurological damage in children and pregnant women.

⚠ HIGH RISK
🧪

PFAS "Forever Chemicals"

Synthetic chemicals that don't break down. Linked to cancer, thyroid disease and immune system damage globally.

⚠ HIGH RISK
🦠

Bacteria and Viruses

E. coli, coliform and waterborne viruses cause gastrointestinal illness — especially dangerous in regions with ageing infrastructure.

⚠ HIGH RISK
☢️

Arsenic

A naturally occurring toxin found in groundwater across South Asia, Latin America and parts of Africa. Linked to cancer and organ damage.

● MEDIUM RISK
🌊

Nitrates

From agricultural runoff and fertilisers. Dangerous for infants under 6 months, causing "blue baby syndrome".

● MEDIUM RISK
🪨

Chlorine Byproducts

Trihalomethanes form when chlorine reacts with organic matter. Prolonged exposure may increase cancer risk in treated water systems.

✓ LOWER RISK

About tap water safety

Tap water safety varies enormously across the world. In developed nations with strong infrastructure, water goes through multiple treatment stages before reaching your tap. In many developing regions, ageing pipes, insufficient treatment and contamination remain serious public health challenges.

Warning signs in your tap water

  • Discolouration — yellow, brown or cloudy water.
  • Unusual smell — chlorine, sulphur or metallic odour.
  • Strange taste — bitter, salty or metallic.
  • Local health notice or boil-water advisory in your area.

How to make water safe at home

  • Use an NSF/ANSI 53 certified filter for heavy metals including lead.
  • Use a reverse osmosis system for the most complete purification.
  • Boil water for one minute to kill bacteria and parasites.
  • Use UV sterilisation tablets when travelling in regions with unsafe water.
💡 Traveller tip: Even treated water can upset your stomach in a new country due to different mineral content. When in doubt, filter it or choose certified bottled water.
