Urbanization and the expansion of impervious surfaces have increased stormwater runoff volumes, altered timing, degraded water quality aquatic ecosystems. Runoff from urban areas carries pollutants such as nitrogen, phosphorus, sediments, heavy metals, which can adversely impact physical characteristics receiving waterbodies. Stormwater management programs aim to mitigate these effects using Best Management Practices (BMPs) retain treat on-site. However, in densely developed areas, space constraints high costs often make traditional BMPs impractical. This study assessed effectiveness expanded shale, an engineered material, a filtration medium bioswales, type linear BMP commonly used transportation infrastructure. Thirty scenarios were tested 16 ft (4.9 m) long plexiglass flume shale mixed with sandy clay soil. Due limited scope this study, it focused on assessing removing suspended sediments reducing turbidity. Results showed that achieved removal efficiencies ranging 20% 82% for total solids (TSS) −4% 61% turbidity under different conditions. It outperformed conventional materials sand gravel, requiring less channel length. Remarkably, even small-scale laboratory setting, met sediment standard 80%, demonstrating its potential highly effective material alternative management.
