I suspect this was a bad sample on the part of Island Health. Surfriders sampled the same spot on Aug 20 and got a very low count: https://bwtf.surfrider.org/explore/41/475

A count over 4000 seems insanely high. Maybe the sampler scooped up some contamination, like bird crap? I don't know their methodology though, hard to say.
