Abstract

This study was conducted in the Talladega research watershed (outlet location: 33.76219799, -85.59550775) in the Talladega National Forest (Cleburne County, AL, USA). The watershed drains a non-perennial unnamed tributary of Pendergrass Creek, and contains 0.92 km^2 of mixed coniferous and deciduous forest in the Piedmont Upland physiographic section. Located near Anniston, AL, the watershed spans an elevation range from 345 to 456 m above sea level and is a tributary to the Coosa River (within the larger Mobile-Tombigbee basin). The region has a humid subtropical climate, with mean daily January and July air temperatures of 5.3°C and 25.3°C respectively, and mean annual precipitation of 1,400 mm/yr.

Samples were filtered with a 0.45um PES filter and frozen until analysis. Aqueous concentrations of anions were determined using an IC-3000 IC system (Dionex, Sunnyvale, CA) equipped with Dionex AERS 500 suppressor (2 mm, Thermo Scientific) and Dionex AS auto-sampler (Thermo Scientific). A Dionex IonPac AS15 column (2 mm × 50 mm, Thermo Scientific) with a guard column Dionex IonPac AG15 (2 mm × 50 mm, Thermo Scientific) was used to separate anions using a mobile phase of 38 mM KOH and a flow rate of 0.3 mL/min. The column temperature is 30 °C. Chromeleon software 7.1 is used for system control. Final data tab shows average of triplicates collected

The final data tab includes QA/QC’d averaged data for fluoride, chloride, nitrite, bromide, nitrate, phosphate, and sulfate in ppm with standard deviations. If the sample is below detection (BD), it is denoted as that and highlighted pink. Average NAs indicate analytes were not run or that samples were missing. NA’s in the standard deviations columns could indicate that those samples were not run or that only replicate was able to be analyzed.
