New marine outfall design slashes beach bacteria by up to 99%
The researchers studied how to reduce harmful bacteria on a beach by changing where sewage is released into the sea. They monitored bacteria levels on a beach in South Korea and used computer models to test different sewage release locations. They found that moving the sewage release further out to sea and deeper underwater can greatly reduce harmful bacteria on the beach, making it safer for people to swim. This information can help make beaches cleaner and safer in the future.
