Trend Network for Streams: Water-Borne Constituents
The Trend Network for Streams for the San Joaquin-Tulare Basins NAWQA is made up of 4 sites, 3 of which were previously sampled in Cycle I. Samples will be analyzed for nitrogen and phosphorus nutrient species, major anions (chloride, sulfate, and alkalinity), pesticides, and suspended sediment. Sampling frequency will range from every two weeks to monthly.
