Water safety and contamination alerts in Poland and Czechia

Overview

Water safety challenges in Poland and the Czech Republic have persisted through late 2026, driven by bacterial contamination, cyanobacteria blooms, and chemical concerns. In Poland, widespread contamination issues were noted as early as August. In the Konin district, intestinal enterococci in the Rychwał municipality led to bans on drinking, food preparation, and bathing. In the Jarocin area, the Wyszki supply zone was found to contain coliform bacteria and fecal enterococci. Meanwhile, in the Rawicz district, the Rogożewo zone was declared unfit for consumption due to fecal enterococci, prompting the use of sodium hypochlorite for disinfection. By late August, improvements were noted in Rogożewo, though boiling remained a precaution. However, new alerts emerged in the Pępowo municipality due to coliform bacteria in the Wilkonice supply zone. In mid-September, several new alerts emerged. While the Chwaliszew supply zone was declared safe, other areas faced severe restrictions. In Gniezno, E. coli and coliform bacteria rendered water unfit for consumption or hygiene, necessitating water tankers. In Radomsko, a high-risk warning was issued for the Krępa supply due to arsenic levels of 10.3 µg/l, which boiling cannot remove. In Lower Silesia, coliform bacteria were detected in Chocianów and Raków, while the Łowicz district required boiling in Rogóźno. By late September, contamination in Zławieś Wielka and Trąbki Wielkie forced residents to rely on tankers, and Zduńska Wola issued boil water advisories. In the Września district, coliform bacteria were found in Marzenin, and in Płock, intestinal enterococci and coliform bacteria rendered Zdwórz water unfit for consumption. In October, alerts continued. In the Trzemeszno supply zone, Sanepid in Gniezno reported coliform bacteria, requiring residents to boil water for at least two minutes. In the Kąty Wrocławskie commune, E. coli detection rendered water unsafe even after boiling.
