Dniester River Contaminated by Russian Attack, Spills to Moldova

What Happened

After a rocket and drone attack by Russia, the Dniester River was found to be contaminated with technical oils near the village of Lyadova, which is part of the Yaryshiv community in the Mohyliv-Podilskyi district of Vinnytsia Oblast. The pollution has reportedly flowed downstream to the village of Naslavcha in Moldova.

The contamination is believed to be linked to a leak of transformer oils from infrastructure at the Dniester Hydroelectric Power Station in Chernivtsi Oblast, caused by the attack on March 7, 2026. The Ministry of Economy, in collaboration with various agencies including the State Emergency Service and local administrations, has initiated consultations to address the situation.

Key Details

The deputy minister, Iryna Ovcharenko, characterized this incident as another manifestation of ecological aggression by Russia, underscoring a transboundary water security threat that warrants international legal assessment. Ovcharenko stated that this incident demonstrates Russia’s continued targeted aggression, not only against Ukraine but also against the environment.

Efforts are underway to control and minimize the impact of the pollution. In both Vinnytsia and Odesa regions, appeals to manage technological and ecological emergencies have led to meetings that outlined actions necessary for localization and disposal of the contamination.

Why It Matters

This incident raises significant concerns regarding environmental safety and cross-border ecological impacts, highlighting ongoing risks posed by military actions. The contamination threatens water supplies for both Ukraine and Moldova, potentially affecting public health and local ecosystems.

Background

Ukrainian authorities have promptly informed Moldovan partners about the cross-border pollution, and plans for collaborative action have been initiated. Following coordination with Moldova, emergency services will establish barriers and employ sorbents to mitigate the situation.

Water samples were taken on March 10 from the Dniester near the contamination zone. Observations in Mohyliv-Podilskyi revealed oily patches on the water's surface, while in the vicinity of the village of Kozliv, a thin greasy film was noted.

In the area near the village of Nahoryany, oil films exhibiting a rainbow effect covered a significant part of the river's surface, accompanied by a strong smell of technical oils. Measurements taken showed pollution levels exceeding regulatory limits by 2.5 times near Nahoryany.

To monitor potential downstream movement of the pollution, additional water samples were collected on March 11, including areas near Odesa's drinking water intake. An extraordinary meeting of the Dniester Commission was held on March 12 to synchronize operations between Ukrainian and Moldovan services.

The Dniester River is crucial as a water supply source for both Odesa and Chișinău, making the presence of technical oils in water bodies a severe threat to public health and aquatic ecosystems.
