Ballast water drain from the ship close-up

Sample kit ballast water

In addition to invasive aquatic species, ballast water also contains a large diversity of (harmful) organisms, such as bacteria and viruses. The IMO has strict requirements for the control and management of ballast water in the form of two standards: D1 and the more stringent D2. For ships sailing in US waters, there are additional regulations, such as the obligation to test for vibrio cholerae.
