The widespread rains across the state are going to have a major impact on water quality for recreational swimmers for some days to come, according to EPA Victoria chief environmental scientist Professor Mark Taylor.
Heavy rain has swept the state, including in Maribyrnong and Hobsons Bay, filling our rivers, creeks and lakes. As it flows, it picks up debris, natural and manmade, reducing water quality and increasing the risk from waterborne contaminants.
Professor Taylor said from floodwater assessment work last year EPA knows that all waters in conditions like these will have reduced water quality and people should avoid contact with affected waterways for at least 48 hours.
“There are still many families who will be enjoying waterside holidays and as the weather eases will be keen to get back into the water,” he said.
“Check the water and if it’s discoloured or smells badly and it’s been raining recently, then avoid swimming or other activities like kayaking and canoeing. And never enter flood waters.”
Professor Taylor said the rain is picking up everything from road-based dirt and grease to animal faeces and vegetation creating increased risk of gastro or skin rashes.
“The waterways that empty into Port Phillip Bay will also be affecting water quality, so you should continue to check the EPA Beach Report but expect conditions to be Poor for several days,” he said.
