A microbiological water quality indicator exceeding the permitted limit has been detected in the Bystrytsia-Nadvirnianska River within the Nadvirna community in Ivano-Frankivsk Oblast.
Water samples were collected on 29 June 2026. Laboratory testing was conducted by specialists from the Nadvirna District Department of the State Institution “Ivano-Frankivsk Oblast Centre for Disease Control and Prevention of the Ministry of Health of Ukraine.”
According to the information made public, the water met established standards for 20 tested parameters. However, the index of lactose-positive coliform bacteria (LPCB) reached 24,000 CFU/dm³, compared with the permitted limit of no more than 5,000 CFU/dm³ for recreational waters. This represents an exceedance of 4.8 times.
Due to the detected microbiological contamination, swimming in the river is currently considered unsafe. The Nadvirna municipal authorities have contacted the State Environmental Inspectorate of the Carpathian District to identify and address possible sources of contamination. Repeat laboratory testing is expected to be conducted the following week.
Why Microbiological Water Contamination Is Dangerous to Human Health
Elevated levels of coliform bacteria are an important indicator of poor sanitary water quality. During swimming, people may accidentally swallow contaminated water, while exposure to microbiologically polluted water may increase the risk of acute gastrointestinal illness.
Possible symptoms following exposure to contaminated water include diarrhoea, abdominal pain and cramps, nausea, vomiting, and fever. Particular caution is advised for children, older people, and individuals with weakened immune systems.
At the same time, it is important to distinguish between an indicator of contamination and a specific disease-causing pathogen. An elevated LPCB index does not in itself mean that a particular pathogen has been confirmed in the water. Separate laboratory testing is required to establish this.

What Could Cause the Contamination
The specific source of contamination in the Bystrytsia-Nadvirnianska River has not yet been publicly identified. In general, possible causes of microbiological contamination of surface waters may include:
discharge of untreated or insufficiently treated domestic wastewater;
accidents or leaks from sewerage systems;
surface runoff following heavy rainfall;
entry of livestock waste into waterways;
poorly maintained cesspits and local sanitation systems near watercourses;
other local sources of contamination within the river catchment.

The actual cause in this specific case should be established by the competent authorities through inspections and additional investigations.

What Residents Should Do
Until the results of repeat laboratory testing are made public, residents are advised to avoid swimming in the section of the river covered by the warning. River water should not be swallowed or used as drinking water without appropriate treatment and disinfection.
Anyone who develops diarrhoea, vomiting, fever, or severe abdominal pain after contact with the water should seek medical advice.

Position of Our Home – Manyava
This case once again demonstrates that Carpathian rivers need not only reactive measures but also systematic water quality monitoring. Recreational waters should be tested regularly, communities should have open access to monitoring results, and sources of contamination should be identified promptly.
Clean rivers are not only an environmental issue. They are also essential to public health, community safety, and quality of life across the Carpathian region.
