Punjab Pollution Control Board probe finds no industrial pollution behind Sutlej Fish deaths
Kanwar Inder Singh/ royalpatiala.in News/ April 24,2026
The Punjab Pollution Control Board (PPCB) has completed a detailed field investigation into the reported fish mortality in the River Sutlej near Harike Head Works in District Ferozepur.The findings indicate that no toxic contamination suggesting industrial pollution was detected in the sampled stretch of the river based on the parameters analysed.
The Board received a video on April 3, of the previous day, showing dead fish. A team from PPCB traced the site around Harike Head Works near the village Gatta Badshah/Dineke the very next day, with scientific staff and the Department of Fisheries. Field observations confirmed the presence of dead fish at multiple points downstream of Harike Head Works, particularly near the fish ladder and within specific gates of the barrage; and no dead fish at the upstream.
Primary testing results show normal oxygen and acidity level, suitable for aquatic life. The sample results show no severe toxicity level, which insinuates that these fish did not die due to any industrial pollution. Water quality analysis across multiple sampling points showed.
Dissolved Oxygen (DO) levels largely ranged between 6.2–7.7 mg/L, suitable for aquatic life. pH levels ranged from 6.8 to 7.5, within acceptable limits.
Analysis of heavy metals, trace elements and pesticides were also found within prescribed limits.
Fish samples collected by the Department of Fisheries and analysed by Guru Angad Dev Veterinary and Animal Sciences University also could not trace the exact cause of mortality due to the samples being at the advanced state of decomposition.
Past history suggests that fish mortality is common during breeding season i.e.April and May.
Further investigation by the Board continues to explore any localised or other reasons of the fish mortality at the Satluj.
