The closures and advisories affect beachgoers, swimmers, and local communities relying on these areas for recreation and tourism. Health risks include gastrointestinal issues, skin infections, and respiratory problems from exposure to contaminated water. In New York, Massachusetts, and New Jersey, coastal communities are particularly impacted, while inland states like Iowa face similar challenges at lakes. Washington's closures disrupt summer plans in the Seattle area. Elevated bacteria levels, such as enterococci and E. coli, serve as indicators of potential pathogens, posing risks to both humans and pets.
