The Bucha District State Administration officially warned the population about the contamination of water bodies in the Borshchahivka rural territorial community. As a result of the incident, a mass fish kill was recorded, which became a signal for the immediate introduction of restrictions on the use of water resources. The warning specifically concerns residents not connected to the centralized water supply. According to local authorities, the Borshchahivka River — a right tributary of the Irpin — became the site of the entry of substances of unknown origin. This led to a sharp deterioration of the ecological situation and the death of a significant number of aquatic inhabitants. ### Response measures and laboratory research In response to the emergency, experts have already taken water samples and samples of dead fish for detailed laboratory research. The goal is to establish the exact source of pollution, determine the composition of hazardous substances, and assess the extent of the affected zone. The results of the tests will be published in the near future, but it is already known that the situation requires immediate action. At the same time, work has been organized to collect and dispose of dead fish. This is necessary not only to prevent the spread of possible contamination but also to minimize sanitary risks for the population and the ecosystem as a whole. ### Versions of the causes of pollution One of the most likely versions of the occurrence of the ecological disaster is the leakage of sewage during repair work at one of the industrial facilities in Kyiv. According to experts, pollutants could have entered the region's water bodies through the stormwater drainage system, which connects urban and suburban areas. This version has not yet been finally confirmed, but it is being actively investigated by the State Ecological Inspectorate and the State Food and Drug Administration. Both structures have already taken the situation under control and are conducting joint inspections. ### Contradictory data At the moment, there are discrepancies in the assessment of the scale of pollution. Some sources indicate that the pollution is limited only to the section of the Borshchahivka River, while others report the spread of toxic substances over significant sections of the Irpin. There is also no consensus regarding the exact time the leak began — some experts cite August 11, while others suggest the process may have started earlier. These contradictions require further investigation and clarification of data from independent experts and government agencies. ### Recommendations for the population Local authorities urge residents to refrain from using water from the Irpin River and its tributaries for drinking, cooking, and household needs. It is also recommended to limit access to water bodies, especially for children and pets. In case of symptoms of poisoning or skin irritation, you must seek medical help immediately. The situation remains under the close attention of authorities and environmental services. It is expected that in the coming days, the first results of laboratory tests will be published, which will help clarify the scale and causes of what happened. ## ❓ FAQ ### Q: What happened in Borshchahivka? **A:** A mass fish kill was recorded due to the pollution of the Borshchahivka River, a tributary of the Irpin. ### Q: Can I use water from the river? **A:** No, the use of water from the Irpin River and its tributaries is prohibited until the causes of pollution are determined. ### Q: What is the cause of pollution? **A:** One of the versions is a sewage leak from Kyiv through the stormwater drainage system.
