A sudden appearance of white, frothy foam on the Periyar River near the Edayar industrial zone prompted Kerala’s Pollution Control Board to serve a formal notice on Fertilizers and Chemicals Travancore Ltd (FACT). Officials say the notice stems from earlier suspicions of illegal discharge and elevated oil‑grease levels in river water.

  • White foam observed on the Periyar on September 1, 2026.
  • Kerala PCB issued a notice to FACT under the Water (Prevention and Control of Pollution) Act.
  • Oil‑grease levels in water samples rose by about 2 mg/L, source still under investigation.

On September 1, 2026, the water of the Periyar River near the Edayar industrial area turned an unusual white colour and formed a thick layer of frothy foam. The incident quickly attracted the attention of local residents, environmental groups, and media outlets.

The Kerala State Pollution Control Board (PCB) – through its Environment Surveillance Centre in Eloor – served a formal notice to Fertilizers and Chemicals Travancore Limited (FACT) invoking provisions of the Water (Prevention and Control of Pollution) Act. The notice demands an explanation for the alleged violation and warns of possible enforcement action if compliance is not demonstrated.

PCB officials collected water samples from four affected points along the river. Laboratory analysis revealed oil and grease concentrations ranging from 4.8 mg/L to 6.5 mg/L, roughly 2 mg/L higher than levels recorded four months earlier. While the initial results are inconclusive about the exact source, authorities have ordered further testing.

FACT representatives acknowledged the board’s earlier alert about a similar white‑foam layer observed during the March‑April summer peak. They suggested that an old leachate deposit near the river – not confined to their plant – might be responsible and that remedial measures prescribed by the board are already underway. FACT rejected the claim that the September foam was a direct discharge from its unit.

Historical Background: The Periyar basin has long been a flashpoint for industrial pollution in Kerala. Chemical and fertilizer factories have repeatedly been cited for discharging untreated effluents, leading to deteriorating water quality, fish kills, and adverse impacts on agriculture downstream. Repeated violations have prompted the state to tighten effluent standards, though enforcement gaps persist.

The river is a lifeline for thousands of villages that rely on it for drinking water, irrigation, and fisheries. If the foam is proven to be industrial in origin, it could jeopardize public health, disrupt livelihoods, and trigger broader regulatory scrutiny across the state’s manufacturing sector.

Why This Matters

BozokMedia analysis shows that repeated violations in the Periyar basin could trigger stricter federal oversight and compel factories to adopt advanced effluent‑treatment technologies, setting a precedent for other polluted waterways across India.

“If rising oil‑grease concentrations are not curbed promptly, the ecological balance of the river will collapse, affecting both biodiversity and local economies,” says environmental scientist Dr. Anjali Rao.
Did You Know?: The Periyar River basin covers roughly 7,500 sq km, making it one of Kerala’s most vital water resources.

Frequently Asked Questions

Q1: Has FACT provided a formal response to the PCB notice?

A: FACT has submitted a written explanation, asserting that remedial steps are underway and that the foam may stem from an older leachate deposit rather than a recent discharge.

Q2: What risks does the foam pose to local communities?

A: If the foam contains industrial contaminants, it could affect drinking water safety, agricultural irrigation, and fish stocks, potentially leading to health issues and economic losses.
