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.

Thanks, everyone for getting the samples this Saturday
Some unexpected high counts in the west side ditches and especially The Bowl in Hanalei. 
The Bowl sample had a low salinity, approximately 1/3 of the water was fresh and I guess polluted.
Anyone hear of a sewage spill or overflowing cesspool? 
Waikomo Stream at Koloa Landing was lower than usual, probably because it was high tide and salt water went far upstream diluting out the bacteria. 
Same probably happened at Niumalu County Beach Park. 
Since you can’t tell how polluted a stream is by looking at it, stay out or rinse off really well when coming out of the waters listed in Red
