Drinking water in your country

How many people have safe drinking water at home, country by country, from the official WHO/UNICEF figures. Then: how to check your own water, wherever you live.

What the figure means. The WHO/UNICEF Joint Monitoring Programme counts the share of people using a safely managed drinking-water service: water from an improved source that is on the premises, available when needed and free from faecal and priority chemical contamination.

This is a national figure, not a statement about your tap. Countries without enough data have no estimate and are not listed. Source: WHO/UNICEF JMP via the World Bank (SH.H2O.SMDW.ZS), reference year 2024, read 3 November 2026.

How to check your own water, wherever you live

Start with the official results. Ask your water supplier, or the authority that regulates it, for its latest test results. Many publish them for free, and some offer a free test at your tap.
Own well, borehole, tank or refill station? These are not covered by the supplier's tests. Ask your local health authority which test it recommends.
A certified laboratory test is the most reliable household option for germs, lead, arsenic, nitrate or fluoride. Only pay for a test whose result would change what you do.
Test strips and TDS meters answer narrow questions, such as hardness. A TDS reading is not a safety score: low can still contain a contaminant, and high can be mostly harmless minerals.
Boil-water notice or contamination alert? Follow your water supplier or health authority.

The WHO guideline values in one list

E. coli (a sign of faecal contamination): not detectable in 100 ml
Lead: 10 µg/l
Arsenic: 10 µg/l (provisional)
Nitrate: 50 mg/l
Fluoride: 1.5 mg/l
Hardness and total dissolved solids: no health-based value; they affect taste, soap and limescale
