Dr. Rick Bennett, PhD, is a Kona Coast Waterkeeper, a title bestowed on him by The Water Keeper Alliance, International, which has been in operation since the 1970s.   He and Island Conversations host Sherry Bracken talk about bacteria in the Big Island's ocean water, how it's monitored, and the impact of sun.  And the need for people who live along Ali'i Drive, especially, consider allowing having a weather monitoring station on their property to monitor the amount of ultraviolet light, which helps keep tabs on the ocean.
