Industrial pollution allegations surface after mass fish deaths in Assam’s Kharkhari river

Thousands of fish have been found dead in the Kharkhari River in Assam’s Boko area, raising concerns over possible industrial pollution and its impact on local livelihoods and aquatic biodiversity.

The incident was reported along a stretch of the river from Shola to Trilochan, where residents observed large numbers of dead fish floating in the water and scattered along the riverbanks. Species reportedly affected include Puthi, Khalihna, Dorikona and Borali, all of which are commonly found in the river ecosystem.

Local residents have alleged that untreated industrial effluents discharged from the Chaygaon Industrial Centre may have contaminated the river water. Community members have specifically raised concerns about the operations of Brahmaputra Biochem Pvt. Ltd., alleging that wastewater released from the facility has entered the river without adequate treatment.

Residents stated that similar incidents have been reported on multiple occasions in recent years. They claim that despite repeated complaints and concerns raised before the authorities, effective corrective measures and monitoring mechanisms have not been implemented.

The recurring fish deaths have affected families dependent on fishing and river-based resources for their income. Local fishermen expressed concern over declining fish populations and the potential long-term impact on their livelihoods.

Environmental observers have warned that continued discharge of pollutants into the river could result in significant ecological damage, affecting aquatic habitats, biodiversity and water quality. Experts note that prolonged contamination may also have implications for food security and public health in communities that rely on the river.

The incident has renewed calls for a comprehensive investigation into the cause of the fish deaths and stricter enforcement of environmental regulations governing industrial operations in the region. Residents have urged the concerned departments to conduct water quality assessments and take appropriate action to prevent further ecological degradation.

Authorities had not issued an official statement on the matter at the time of filing this report.
