The discharge was caused by a breakdown at a pumping station, which allowed the release of effluents into the river. Environmental authorities have been monitoring the situation to assess the impact on aquatic ecosystems. Data collected through monitoring indicate that the river is gradually recovering from the consequences of this accidental discharge.
