This new facility provides the Navy with the capability to research, develop, test and evaluate solutions to eliminate or remove aquatic nuisance species from residual water and sedimentation that remain inside ships’ ballast tanks. The lab can also be used to investigate various ballast water-treatment components and sensors to evaluate their suitability for Navy-specific integration. (U.S. Navy photo by Monica McCoy/Released)
