Dredging Turns Port Phillip Bay Black, Sewage Leak Intensifies Odour
St Kilda, Victoria – dredging operations in Port Phillip Bay have turned the water a deep black color and unleashed a potent, sulphur-like odour that residents are comparing to rotten eggs.The discolouration and smell are a combined result of naturally occurring organic material disturbed during dredging and a separate, recently repaired sewage pipe break, authorities confirmed.
the dredging, undertaken at the entrance of the St kilda Marina channel, is intended to clear a buildup of sand. However, the process has stirred up decades of decomposed plants and animals from the seafloor, releasing sulphur into the water and air. Simultaneously, a broken sewage pipe – now fixed – contributed to the unpleasant smell, compounding concerns among locals. The Environmental Protection Authority (EPA) assures residents the odour should dissipate within days, but the visual impact of the black water has raised questions about the environmental effects of the dredging.
Workers are currently depositing the dredged sand onto the beach at Shakespeare Grove, near Luna Park. The dark colour of the sand is due to the high concentration of organic matter. as the material is disturbed, sulphur is released, creating the strong, noticeable smell.
The EPA stated the odour, while unpleasant, does not pose a health risk. The agency is monitoring the situation and working with the responsible parties to minimize disruption. Residents experiencing concerns are encouraged to contact the EPA directly.
