From source to streams: New national models estimate seasonal nutrients over 21 years in rivers across the U.S.

aaarcher@usgs.gov — Mon, 20 Jul 2026 08:01:05 EDT

Excess nutrients such as nitrogen and phosphorus in streams can lead to the need for costly water treatment and ecosystem management. New USGS nutrient models examine how nutrients move from landscape to streams, including how past pollution affects water quality today. These models quantify nutrient loads (by source), yields, delivery, and concentrations seasonally over time.
