The Periyar River, a vital waterway in Kerala, turned disturbingly white near the Edayar industrial area on Tuesday morning, developing a thick layer of frothy foam that stretched across the water near the Pathalam bund. Local residents first spotted the alarming phenomenon around 7:30 a.m., immediately alerting officials at the Environment Surveillance Centre in Eloor.

Key facts

  • White froth appeared on Periyar River near Edayar industrial area
  • Incident occurred on Tuesday, September 1, 2026 around 7:30 a.m.
  • Kerala State Pollution Control Board collected water samples for testing
  • Similar incident occurred in the same area on August 22, 2026

Pattern of Pollution Emerges

This marks the second time in just over a week that the river has exhibited these troubling symptoms. Purushan Eloor, spokesperson for the Periyar Malineekarana Virudha Samithi, expressed deep concern about the repeating pattern. "We suspect that the discharge of untreated waste from the bonemeal and chicken waste rendering units in Edayar industrial area may have resulted in the white froth visible on the river since morning," he said. The familiarity of the situation weighs heavily on community advocates who have watched this stretch of river struggle with industrial impacts for years.

Official Response and Testing

The Kerala State Pollution Control Board moved quickly to collect water samples, though officials caution that they must await laboratory results before confirming the exact cause. The timing feels particularly significant—this incident occurred just one day after a meeting convened by the board that brought together elected representatives from Eloor municipality, Kadungallor panchayat, and environmentalists. At that gathering, participants raised serious complaints about air pollution allegedly caused by non-compliant units in the very same industrial area.

Broader Environmental Concerns

This isn't just about one day's foam on the water. A September 2023 study by the CSIR-National Institute for Interdisciplinary Science and Technology found that biofilters used to remove pollutants and odor from air impacted by industrial processes were not functioning properly in units involved in rubber, meat and waste processing. The board has now decided to issue show-cause notices to nearly 20 such units, demanding explanations for why action shouldn't be taken against them for lapses in implementing necessary pollution control measures.
