The attenuation of a diverse suite of contaminants of emerging concern (CECs) and bulk water quality changes was evaluated at a surface-spreading aquifer recharge operation across a detailed subsurface profile (9 locations), representing both short- and long-travel times (10 h to 60 days). Seventeen CECs were detected in the recharge basin and the concentrations of all were reduced during soil aquifer treatment (SAT), with 11 of the target compounds attenuated by > 80% after 60 days of travel time. Select CECs (atenolol, gemfibrozil, N,N-diethly-3-methylbenzamide, meprobamate, tris(2-chloroethyl)phosphate, and primidone) and bulk water organic-carbon measurements (total organic carbon, biodegradable organic carbon, size-exclusion chromatography and fluorescence excitation–emission matrices) were identified as monitoring parameters that can be used to assess SAT performance at surface-spreading operations.
Research Highlights
► Seventeen CECs detected during surface spreading; concentrations reduced during SAT.
► Chemical and biological removal of CECs was considered after accounting for dilution.
► Select CECs and bulk parameters were identified for monitoring SAT performance.
