Short summary
The mitigation of excess nitrogen and phosphorus in river waters requires costly measures. Therefore it is essential to use reliable monitoring methods to select adequate mitigation strategies. Here we show that more development is needed before passive samplers can be considered as reliable alternative for sampling nutrients in stream. We also showed that although continuous sampling is expensive, its reliability precludes unnecessarily high implementation costs of mitigation measures.
