Fertilizers reach bodies of water in a variety of ways, most noticeably by rain washing the fertilizer into adjoining rivers and streams.
However, all things contain water and water is a particle carrier, so the chemicals of fertilizers are transported to large bodies of water by all means, including by humans who are eating the fertilized food.
Humans are 97% water at birth and pass through undigested fertilizer into waste delivery systems that return to the Water Cycle. Same with animals who are mostly made of water, themselves.
Ultimately, humans made fertilizer and so fertilizers start their journey from human hands and so part of that answer is: humans.
