National Park Service sees positive results in ballast water testing

Wed, 12/17/2014 - 3:06pm

The National Park Service continues its efforts to prevent the spread of aquatic invasive species. Invasive species such as the zebra mussel have caused extensive damage to natural resources and cost millions of dollars in eradication and control efforts. Ballast water discharges from ships (water used for ship stability) is a primary pathway for introduction of invasive species. The NPS and its partners have conducted significant research into ballast water treatment technology, most recently this summer at Isle Royale National Park.

Results are in from the summer testing of two freshwater ballast treatment systems on the NPS ship Ranger III. The NPS tested a manually operated rapid response treatment process that used chlorine and a neutralizer and a fully automated permanent treatment system using filtration and ultraviolet (UV) technology. The shipboard status tests were conducted in September 2014 and the final report was recently released. Both systems passed United States federal and international standards for two out of three requirements: discharge of living zooplankton and indicator bacteria.

The systems did not meet the standards for phytoplankton, which remain some of the toughest organisms to kill. Since the numbers of live phytoplankton collected exceeded the standard, the test facility conducted a viability analysis. After giving the organisms optimum conditions for growth and reproduction it was determined they were not viable (not capable of reproduction) after undergoing either of the treatments.

More information on results and criteria will be posted on the Isle Royale website, www.nps.gov/isro.
