Water quality in Steele Creek has returned to normal following contamination from a petrol tanker crash.

The EPA has been monitoring the water since 15,000 litres of fuel entered the creek after an accident on the Calder Freeway in May.

Warning signs asking people to avoid contact with the waterway, between Keilor and Rosehill roads, will be removed after confirmation no more traces of fuel remained.

About 175,000 litres of contaminated water, including fuel and firefighting foam, was removed from the creek during the immediate cleanup after the crash.

Floating booms were used to contain and absorb any remaining contaminants and were removed last Thursday.

Moonee Valley Council will work with Friends of Steele Creek to monitor the creek and vegetation in the affected area for any long-term impacts.
