Photo Story
Sewage Outfalls – The greatest volume of waste discharged into the ocean, by far, is sewage. Sewage contains a wide range of pollutants including toxic chemicals, natural and synthetic hormones, pharmaceuticals, pathogens, and organic matter. Nutrients and decaying organic matter can lead to eutrophication and facilitate the formation of harmful algal blooms.
