That's rather hard to believe when parsed out, isn't it?
Anyway, look it all up instead of using your intuitive rice paddy analogy. Heavy metals, pathogens and pharmaceuticals are issues in sludge from treatment plants. None would be the same from wild animals. The sources you refer to, such as drinking from the water, are substantially diluted compared to human consumption, which consumes pure product.
