Water Contamination has become a significant problem on a global scale. Especially in New Zealand, with over one hundred thousand people getting ill from drinking dirty water every year. A team of Science Researchers from the University of Auckland are tackling this problem, as they look to investigate a way to detect waterborne contamination using new laser technology. Joe talks to the head researcher of the project, Dr Alex Risos, and how his research has revolutionised the way we protect our waterways.
