Public health officials in several U.S. coastal regions have issued warnings due to elevated bacteria levels in ocean waters. In early September, Florida and California reported bacteria concentrations exceeding safety standards. In Miami-Dade, Florida, officials advised against water activities at Crandon Park North due to high enterococci levels, which may stem from stormwater runoff, septic leaks, or wildlife. Simultaneously, Los Angeles County issued warnings for ten locations, including Santa Monica Pier and areas in Redondo and Hermosa Beach. By a few days later, the scope of advisories expanded to include Oregon. The Oregon Health Authority issued an advisory for Siletz Bay in Lincoln County, warning of risks such as skin rashes and respiratory infections. In California, Los Angeles County maintained warnings for nine coastal locations, including Santa Monica, Torrance, and San Pedro beaches, while noting that some previous advisories for Paradise Cove and Catalina Island had been lifted. By mid-September, health warnings persisted in California. The Los Angeles County Department of Public Health issued advisories for several beaches in Malibu and Santa Monica, specifically naming Malibu Lagoon, Topanga Canyon Beach, and the Santa Monica Pier. On September 21, health officials in Palm Beach County, Florida, issued new advisories following elevated Enterococcus bacteria levels and a wastewater spill. Testing identified bacteria levels failing to meet state criteria at Ocean Inlet Park in Boynton Beach, the Boynton Beach site in Ocean Ridge, and DuBois Park in Jupiter. Furthermore, a wastewater spill near the Boca Raton Resort reached waters connected to the Intracoastal Waterway. Officials advised against swimming, water contact, or using the water for irrigation in the affected area, though they noted the spill has not affected the drinking water supply.
