PUPUKEA, Hawaii (Island News) -- A green glow in the waters of Sharks Cove is drawing attention on the North Shore, but the unusual color is part of a scientific study investigating a long-standing community concern. Mālama Pūpūkea-Waimea and Wastewater Alternatives and Innovations (WAI) recently injected a non-toxic fluorescent dye into the wastewater system serving the restrooms at Pūpūkea Beach Park. The dye was later detected in the Kapoʻo, or Sharks Cove, tidepools. That confirms a connection between the park's wastewater system and the ocean. “We injected green fluorescent dye into the restrooms and waited,” said Jenny Yagodich, director of educational programs and Makai Watch coordinator for Mālama Pūpūkea-Waimea. “We were going to see whether or not we were going to see green in the water, and we did.” Why is the water green? The green color is not sewage itself, and researchers said the dye being used is non-toxic. Instead, the dye acts as a tracer, allowing researchers to see where water from the wastewater system is traveling. Christina Comfort, water quality program manager with WAI, said instruments called fluorometers can also detect the dye at concentrations too low to see with the naked eye. “The green dye is...
