Sal River Suffocating: Zero Oxygen, Sewage Flood
19 Mar
Summary
- River parts register zero dissolved oxygen, critical for aquatic life.
- Untreated sewage and fish waste dumped directly into river systems.
- Water quality data shows sustained organic pollution overwhelming river.
The Sal river in Goa is experiencing a severe ecological crisis, with critical sections showing zero dissolved oxygen levels and continuous sewage discharge. Official water quality data from 2025, presented recently, indicates dissolved oxygen dropped below detectable limits for five consecutive months at one monitoring point, far below the safe limit of 6mg/l for aquatic life. This indicates a collapse of aquatic conditions, primarily due to untreated sewage and decomposing waste.
Ground inspections have corroborated the data, revealing untreated wastewater from the SGPDA wholesale fish market being discharged directly into storm drains leading to the river. Similar issues persist near the South Goa District Hospital, with overflowing manholes spilling sewage, and in Fatorda, where freshwater nullahs show signs of recent sewage contamination. This pollution is also affecting agricultural lands, and water clarity has deteriorated significantly.
Water resources minister Subhash Shirodkar has ordered a systematic clean-up, emphasizing the need to stop direct sewage inflow as a priority. He described the Sal river as the "lifeline of Salcete" and stressed that its restoration requires both administrative action and public participation. Experts warn that irreversible ecological damage could occur if swift, coordinated enforcement against illegal waste disposal and poor compliance with effluent treatment systems is not implemented immediately.
