Dangerous Bacteria Levels Rise at Beaches in Los Angeles, Wales, Boston

Multiple locations across the United States and the United Kingdom are currently under advisories or warnings due to elevated levels of harmful bacteria in recreational waters. In Los Angeles County, health officials have warned residents to avoid water at several beaches including Topanga Canyon Beach and Puerco Beach due to bacteria levels exceeding safety standards, while previous warnings at other beaches have been lifted after water quality improved. In north Wales, unsafe intestinal enterococci bacteria levels were found at Llandudno's West Shore, leading to swimming restrictions amid concerns over pollution sources, with investigations ongoing to identify the contamination origin. Chicago's Dog Beach remains open but with a swim advisory in place due to increased risk of water-related illness from elevated bacteria levels. Additionally, in Boston, a toxic cyanobacteria algae bloom was reported in Hyde Park's Sprague Pond, prompting public health officials to advise against contact with the water and shoreline due to potential health risks, with monitoring ongoing until it is safe to reopen. These advisories reflect growing concerns about water quality and public health during peak beach and recreational seasons.
