Epidemiological Studies and Beach Water Pollution
- "Many people know that beaches can be closed or posted with swimming advisory signs due to harmful levels of bacteria in the water. But did you ever wonder how those levels were determined, what types of bacteria are tested for and what exactly "harmful" means? Well, it all starts with health studies called epidemiological studies, or "Epi" studies for short." - excerpt from Surfrider Foundation's Coastal A-Z article, Epidemiological Studies.
