The delegation included medical representative Nebojsa Nikolic, who praised a new pipe belt built to block sewage and the use of eco barriers to trap rubbish. "I am satisfied with the planning work that is being done ahead of the Games to ensure that the welfare of sailors remains the top priority and that appropriate water testing and protocols are in place to inform decision making at the Games," Nikolic said. "We will continue to monitor water testing data closely and to educate sailors and officials on what they can do themselves to reduce health risks ahead of the Games."
