The popularity of nitrogen-based fertilizers in agriculture for decades has contributed to a vast amount of anthropogenic nitrogen entering the nitrogen cycle. In soil, a significant component of the nitrogen is in its nitrate form, which leaches into waterways. While nitrate is present in water naturally, the extra nitrate can increase the nitrate concentration to […]

Nitrogen from a variety of sources can make its way into groundwater and waterways. A certain level of nitrogen is naturally present in the environment and nitrate in low quantities are necessary nutrients. However, the high levels of nitrate found in major anthropogenic contributors such as agricultural runoff, nitrogen-based fertilizers, animal manure and sewage pose […]
