Canada Tests aqua tools' Ballast Water Kit The government of Canada is testing aqua-tools' B-QUA ballast water sampling and monitoring kit in the Canadian ballast water surveillance program. The trials compare the capabilities of sampling and analysis tools for measuring organisms of various sizes, zooplankton, phytoplankton and bacteria. The Canadian laboratory carried out research to bet- ter understand the capabilities of tools, visiting multiple ships and taking samples of treated ballast water. B-QUA proved fully capable of providing analysis of organisms in the 10- to 50-µm and >50-µm ranges.
