Tóm tắt

In this study, we evaluated the oil and grease concentrations in sediment from roadway runoff in detention basins and swales following rain events. The study was conducted in three swales and two detention basins within the Edwards Aquifer recharge zone in San Antonio, Texas and one swale located in the contributing zone. The Edwards Aquifer is the primary source of municipal water for Bexar and surrounding counties and being a karst aquifer makes it susceptible to pollution. Oil and grease was sampled following eight rain events in detention basin (n = 3) and swales (n = 3) from November 2020 to July 2021 using pitfall traps. Mean oil and grease concentrations in detention basins and swales were 723 mg kg
