N1 - Funding Information:
Role of the funding sources . Funds for this study were provided by the Advanced Water Technology Center (AQWATEC) at the Colorado School of Mines (CSM), the WateReuse Research Foundation (WRF) , the Water Replenishment District of Southern California (WRD) , the County Sanitation District of Los Angeles County (CSDLAC) , and the Edna Bailey Sussman Foundation. AQWATEC, WRD, and CSDLAC contributed to the planning and execution of fieldwork. AQWATEC was primarily responsible for data interpretation, report writing, and choosing to publish, with assistance from Theodore Johnson at the WRD.

N2 - 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.
