The Blue Water Task Force is our water quality testing program. It is comprised of a group of individuals who, on the second Saturday morning of the month, paddle out to various surf spots or go to streams on the island, and collect a water sample to be tested later in our lab. We test for Enterococcus bacteria that indicate contamination from feces of warm blooded animals, especially humans. It is the standard test for both the Hawaii Department of Health and the U.S. Environmental Protection Agency.

We also test some of the streams and County Beach parks not tested by the Hawaii Department of Health. We are now testing approximately 25 sites on a regular basis. The monthly results are posted on our website (below) and also on the Surfrider national website.

Surfrider sampling over the years has documented chronic levels of pollution at Hanamaulu stream, Nawiliwili stream at Kalapaki Bay, Niumalu Beach Park, and Waikomo stream at Koloa Landing. More recently we discovered that Waiopili Stream at Mahaulepu is 10 times more polluted with feces than the others above. We provide this data on the website below and to the Hawaii Department of Health and the U.S. EPA, trying to get them to post warning signs at these spots and then take measures to stop the polluting.

If you are interested in participating in the BWTF, or would like to find out more, contact Project Manager Dr. Carl Berg: 808-639-2968 or

With little rain recently, ocean sites are nice and clean and stream sites have slightly lower Fecal Indicating Bacteria concentrations than their means concentrations for the winter months.
Still the ditches and canals are polluted.
The Hawaii Department of Health has yet to put up caution signs at even some of the chronically worst sites (Moloa’a stream mouth, Waikomo stream at Koloa landing, Nawiliwili stream at Kalapaki, and all 3 canals in Kapa’a).
Surfrider is insistent that those places get “Caution” signs.
If you know of  friends getting sick from being in those waters and/or have photos of people playing in the waters, tell the Clean Water Branch in Honolulu by emailing
