If the water is brown, turn around…too much bacteria, chemicals, dead animals, sharp debris and sharks.
Some surf sites had low salinity, indcating river runnoff and thus unusually high counts (Rock Quarry, The Bowl, Kalapaki). The Dept. of Health had high (192) bacteria counts at Koloa Landing on Monday, posted a warning sign, then re-tested and said it was fine.
It is not fine, with a mean of 1,481.8 it is chronically polluted and needs a permanent warning sign.
Nawiliwili Stream has a mean of 994.5 and it too needs a permanent sign. 12 of the 31 sites tested this week have mean counts greater than 500, yet only 4 have been posted with warning signs by the Dept. of Health.
Blue Water Task Force needs new samplers for all around the island. If you know someone who is interested in a permanent volunteer position, have them email email@example.com
Here are Surfrider’s results for August 11, 2018
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 30 sites on a monthly basis. The results are posted here, on our BWTF Map, as well as 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.
