Blue Water Task Force
Our Science-Based Approach
The Blue Water Task Force is Surfrider’s volunteer water quality monitoring program that provides critical water quality information to protect public health at the beach. Surfrider chapters use this program to raise awareness of local pollution problems and to bring together communities to implement solutions.
Blue Water Task Force (BWTF) labs measure fecal indicator bacteria levels in recreational waters and compare them to water quality standards set to protect public health. Chapter-run BWTF programs fill in the gaps and extend the coverage of agency-run beach monitoring programs by sampling ocean and bay beaches, estuaries and potential freshwater sources of pollution such as stormwater outlets, rivers and creeks that discharge onto the beach.
2025 Hawaiʻi Water Quality Report
The 2025 Hawaiʻi Water Quality Report provides a statewide snapshot of coastal water quality conditions across Kauaʻi, Maui, and Oʻahu through Surfrider Foundation’s Blue Water Task Force (BWTF) program — the nation’s largest volunteer-run beach water testing network. In 2025, trained volunteers collected 1,138 water samples at 90 sites statewide, helping fill critical gaps in Hawaiʻi Department of Health beach monitoring by testing local beaches, surf breaks, stream mouths, and recreational areas often left unmonitored.
The report highlights statewide water quality trends, Hawaiʻi beach bacteria hot spots, and ongoing clean water advocacy efforts addressing cesspool pollution, wastewater treatment plant discharges, and watershed health. It also features nature-based solutions and community stewardship projects working to improve water quality from mauka to makai, while providing public health guidance to help ocean users recreate more safely at the beach.

Our Local Program
Surfrider Foundation Oʻahu performs water quality testing of over 20 beaches, stream mouths and other coastal recreation sites across the island. Sampling occurs bi-weekly throughout the year.
Our BWTF data augments the beach monitoring program conducted by the Hawaiʻi Department of Health to ensure that our communities are aware of potential health threats at the beach. Our data also helps target areas for further investigation into sources of pollution such as wastewater failures, cesspools, and stormwater runoff, so solutions can be put in place.

Everyone deserves access to clean water to surf, swim and play in.
Community Science Driving Pollution Solutions on West Oʻahu
With the help of local community advocates, Surfrider Foundation Oʻahu Chapter expanded water quality monitoring to four sites in Pōkaʻī Bay (Waiʻanae). The Treat Hawaiʻi Water Better video details the efforts of West Oʻahu community leader Carmen Guzman-Simplicano to improve water quality within Pōkaʻī Bay and the role that community science can play in driving pollution solutions.
