Yellowstone River at Yellowstone Lake Outlet (YYFB)

Yellowstone River at Yellowstone Lake Outlet (YYFB), Yellowstone National Park 
Sample Collection: Samples were collected near the USGS stream gage 06186500 (Latitude 44°34'01.53",   Longitude 110°22'49.46"   NAD83). At the time of collection, all waters samples were filtered through a syringe filter (0.45-micrometer). Two splits of the filtered water were retained for chemical analyses, including an unacidified (FU) sample for determination of anion concentrations and a nitric acid preserved (FA; 1% volume-to-volume concentrated trace-metal grade nitric acid) sample for cation and trace metal analyses. During sample collection, the water temperature, specific conductance, and pH were often measured. 
Sample Analyses: Concentrations of chloride, fluoride, bromide, and sulfate were determined with an ion chromatograph (Dionex ICS-2000). Analytical errors for these constituents were typically less than 2%. Total alkalinity as bicarbonate was determined on stored samples, usually within several months after collection. Ten milliliters of sample were titrated with 0.05 Normal sulfuric acid to the bicarbonate end-point. The analytical error in alkalinity concentrations was roughly ± 5%. Concentrations of cations and trace metals were determined with an inductively coupled plasma-optical emission spectroscopy (Perkin Elmer Optima 7300 DV) following the methods described in Ball and others (2010).
