Treated ballast water and its impact on port water quality
2019
Australian Bureau Of Agricultural Resource Economics And Sciences (ABARES)
The International Convention for the Control and Management of Ships' Ballast Water and Sediments, sponsored by the International Maritime Organisation (IMO), came into force on the 8 September 2017. The Convention regulates the treatment of ballast water to address concerns that ballast water facilitates the spreading of harmful aquatic organisms and pathogens. Australia amended the Biosecurity Act 2015 in 2017 to ratify the Convention and requires domestic and international ballast water to be managed to the Convention’s standards. ABARES was commissioned by the Marine and Aquatic Biosecurity Section in Biosecurity Animal Division to explore the potential impact that the discharge of chemically treated ballast water could have on the water quality of Australian ports.
