Aloha! Welcome to the State of Hawaii Department of Health Clean Water Branch Water Quality Data page. Hawaii is home to many of the world’s most stunningly picturesque beaches. Our year-round swim season and tropical temperatures are complimented by extremely clean water. The Clean Water Branch currently monitors beach water quality monitoring stations at various locations around the state, which can be found in the map above. Data includes bacteria (enterococcus, C. perfringens) and field chemistry (pH, salinity, DO, DO%, turbidity, temperature). Availability and frequency of data varies between locations. Please zoom in or use the "Station Search" to find and click on a location of interest.
