Hi Hazel, good question! There ARE some dangerous bacteria that can lurk in rivers (like e. coli, legionella, and other bacteria that can use illnesses like cholera!) but i mostly look to try and find the helpful types of bacteria, the kind that just happen to live in the river and perform helpful tasks, like cycling nutrients, or breaking down pollutants!
