There are a lot of fish who can easily live in fast past streams, but there are other fish who can’t because they may be too small and/or weak. When there are high levels of nitrate in water, there are high concentrations of algae and that causes the water to be a milky color. Plants use nitrate as a food source, therefore, if there is a boundless source of nitrate, plant growth is free. When there are extremely high levels of nitrate, that can make life difficult for fish and the fish would struggle to survive. Other than that, nitrate has no direct effect on animals.(Wheatley River Improvement Group, no date) Nitrate does not easily enter the body through the skin so it is safe to swim in water that has over 10 mg/L as long as you don’t swallow the water.(Oregon Health Authority, no date) Nitrate is a nonpoint source. A nonpoint source means A few causes can include runoffs from fertilized agricultural land, wastewater, refuse dumps, animal feedlots, private sewage disposal systems, and decaying plant debris.(acceptable levels of nitrate for swimming, 2013) A few management practices can include leaving harvested plant materials on the surface to reduce runoff and soil erosion, managing all nutrient inputs, using various methods for managing pests while protecting soil, water, and air quality, using
