But after years of research, we now have a better sense of the source of this pollution thanks to a new study by Humboldt County's Public Health Lab Manager, Dr. Jeremy Corrigan.
In short, Dr. Corrigan’s research identified birds as the primary source of pollution at Clam Beach, while cattle are the main source upstream in Strawberry Creek.
"Clam Beach is frequented by birds, which adds to the allure of its location and should be celebrated not feared." from Corrigan et al. Microbial Source Tracking Approach to Investigate Fecal Waste at the Strawberry Creek Watershed and Clam Beach, California, USA. Int. J. Environ. Res. Public Health 2021, 18(13), 6901.
