This data set gives the water chemistry sampled at various locations (refer to the map in Other Entities in this data package) throughout the hillslope (lysimeters [L1-L8], primary outlet [Outlet], and auxiliary outlet [Outlet_bottom]), and also untreated inflow (House_untreated), treated inflow (RO_product_hose), deionized water collected at VT (DI_water_VT), and the tracer solution at two dilutions with deionized water (tracer_solution_10mL_and_DI_water_VT_13dot55014mL and tracer_solution_10mL_and_DI_water_VT_14dot81481mL). Column names are in the format: "analyte_unit_analyzer" where the analyzer is either UCD (UC Davis Stable Isotope Laboratory), VT (Water Quality Lab at Virginia Tech), or CWT (Coweeta Hydrologic Laboratory). The hillslope was sampled from June 7, 2017 to December 1, 2017.
