Nitrogen or #nitrate contamination of drinking and surface water poses serious health risks, and can result from agricultural runoff in rivers. It is often associated with algal blooms as well. Also see the topic #phosphate.
Questions can be either frequently asked questions, or "next step" challenges we're looking to solve.
