Abstract
The West Fork of the White River (WFWR) watershed in northwest Arkansas is a trans-ecoregion watershed and is experiencing land-use changes, especially in the downstream portion of the watershed. The entire 54-km long river has been on the State’s 303(d) list of impaired waterbodies for turbidity, total dissolved solids (TDS), and sulfate for many years. The purpose of this study was to identify which part(s) of the river fail to meet applicable water quality standards (WQS) and to investigate possible sources of pollutants, whether human-caused or naturally occurring. Water samples were collected once or twice a month at 9 sites along the WFWR from June 2014 through June 2018 and analyzed for turbidity, TDS, sulfate, and chloride. Median turbidity values ranged from 1.8 to 10.8 NTU and generally increased from upstream to downstream (p
