This summer, millions of Americans will head to the beach to beat the heat. But how clean is the water they're swimming in? At many beaches, especially on the East Coast, water quality is rarely tested for bacteria, pollution, and other health hazards that may be dangerous to both beachgoers and the many species that live in marine habitats. While the importance of clean drinking water is a well-known issue, pollution in swimming water has also become a serious public health issue in some areas of the United States, even causing national security issues for Navy SEALs, Border Patrol officers, and more who use these waters. Mara Dias, Water Quality Initiative senior manager at the Surfrider Foundation, joins the podcast to discuss how the Foundation's Blue Water Task Force helps monitor water quality at beaches across the country and the public health implications of reducing contamination.
