The reported data have been acquired within a research project investigating the ability of infiltration-based Sustainable Drainage Systems to mitigate pollutant fluxes in stormwater runoff. Sorption experiments have been carried out in batch systems, in order to characterize the sorption behavior of three soils towards copper and zinc, and one soil towards four organic micropollutants: Bisphenol A (BPA), 4-tert-Octylphenol (OP), 4-Nonylphenol (4NP), and Nonylphenol Ethoxylate (NP10). The soil samples originate from three source-control infiltration facilities. • Soil 1 is a sandy loam from a roadside swale; • Soil 2 is a silt loam from a roadside filter strip; • Soil 3 is a sandy clay loam from an infiltration basin. All experiments were carried out in non-competitive systems (i.e., individual contaminants in each batch system). The “reference conditions” corresponded to an electrolyte solution which mimicked the composition of runoff water (Evian and ultrapure water, volumetric ratio of 1:10). The sorption behavior of metals onto soils 1 and 3 was also investigated in different conditions: • 1.0 g/L of sodium chloride, to investigate the effects of deicing salt in runoff water; • 10 mg/L of humic acids, to represent the natural generation of dissolved organic matter in the soil solution. The methodology used to select the experimental conditions is thoroughly described in a research article entitled: “Evaluation of contaminant retention in the soil of Sustainable Drainage Systems: methodological reflections on the determination of sorption isotherms” (Blue-Green Systems 1(1), doi: 10.2166/bgs.2019.196). The appended files present the experimental points of the sorption isotherms for each characterized soil. • Soil 1: metals in the reference conditions (Metals_ref), metals with sodium chloride (Metals_NaCl), metals with humic acids (Metals_HA), organic micropollutants; • Soil 2: metals in the reference conditions; • Soil 3: metals in the reference conditions, metals with sodium chloride, metals with humic acids. The concentrations in the dissolved phase are referred to as “X_diss”, where X is the studied species (Cu, Zn, etc.), and are expressed in mg/L. BPA stands for Bisphenol A, OP stands for 4-tert-Octylphenol, 4NP stands for 4-Nonylphenol, and NP10 stands for Nonylphenol Ethoxylate. The contents in the solid phase are referred to as “X_sorb” and are expressed in mg/kg. In case the tests were carried out in duplicates, the columns “X_diss” and “X_sorb” correspond to the mean values of the experiments; two additional columns, referred to as “sdX_diss” and “sdX_sorb”, provide the standard deviations (also expressed in mg/L and mg/kg, respectively).
