Is Tap Water Safe to Drink in Uzbekistan?

Tashkent draws from the Chirchiq River and the Boz-Su Canal, treated at several municipal plants. Samarkand and Bukhara rely on the Zeravshan River. The Fergana Valley cities use Syr Darya tributaries. The Karakalpakstan region near the former Aral Sea depends on the Amu Darya and local wells.

Agricultural pesticides and fertilizer runoff from the cotton monoculture are the dominant contaminants in surface water. In Karakalpakstan, water contains elevated salts, defoliants, and heavy metals linked to the Aral Sea catastrophe. Tashkent’s treated supply is generally acceptable, though distribution pipes leak and can reintroduce bacteria.

Tashkent has the most reliable supply and ongoing infrastructure investment. Samarkand and Bukhara have functional treatment but intermittent delivery. The Fergana Valley cities (Andijan, Namangan, Fergana) have aging systems. Karakalpakstan has the worst water quality in the country, with severe contamination and health consequences.

Hard, typically 200–400 mg/L in Tashkent and the Fergana Valley; very hard in Bukhara and Karakalpakstan due to high mineral and salt content..

Most Uzbek families boil water for tea, which is consumed throughout the day. Drinking unboiled tap water is uncommon in urban areas. In some rural areas, unboiled well or canal water is still consumed.
