Heavy Rainfall Triggers Oil Spill in Uzbekistan’s Surkhandarya Region
Following concerns raised by local residents on social media regarding oily films and discoloured water, authorities in Uzbekistan have confirmed an oil spill in the Surkhandarya region.
The incident occurred after severe and prolonged rainfall on April 23 triggered heavy flooding in the Boysun district. The deluge caused water levels in the Khangaronsoy stream to rise dramatically, ultimately overwhelming temporary earthen dams designed to hold crude oil.
The Ministry of Water Resources explained that the containment facilities were constructed earlier this year by the ERIELL Group. They were built on the left bank of the stream to safely capture and store oil that surfaces during drilling operations before it could be transported away by specialised vehicles. However, the sheer force of the recent floodwaters caused the protective barriers to partially overflow.
This allowed water mixed with residual crude oil to escape into the wider aquatic ecosystem. The contaminated flow travelled through the Bandikhonsoy stream before eventually reaching the main Surkhandarya river which passes through the Kumkurgan district.
Before the official clarification was issued, the Surkhandarya Regional Main Department of Ecology and Climate Change had launched a preliminary investigation. Early assessments incorrectly suggested the strange colour and oily surface were merely natural byproducts of mountain rocks, sediment and other environmental impurities brought down by the floodwaters. Meanwhile the state energy company Uzbekneftegaz quickly released a statement distancing itself from the pollution.
Following the breach the ERIELL Group immediately launched emergency repair work. The damaged earthen dams were reinforced on the same day, successfully halting any further oil from leaking into the water supply.
To prevent similar environmental incidents in the future the Amu-Surkhan Basin Irrigation Systems Authority and other emergency services have increased their surveillance of flood-prone areas. A strict round-the-clock monitoring system is now in place. In the meantime environmental specialists have collected water samples from the affected canal and sent them to a laboratory for comprehensive analysis.
