How does Humboldt County monitor ocean water quality?
From April through October, the 5 beaches between McKinleyville and Trinidad are monitored weekly for 3 types of indicator bacteria. Samples are collected within the creek mouth in ankle to knee-deep surf zone water

Sampling is usually performed on Tuesdays with results available to the public on this website 2 days later. Resamples of beaches that do not meet state bacteriological standards are taken on Thursdays.
