A filtration system and method are provided for removing suspended solids and other affiliated pollutants from stormwater runoff and any other contaminated water. The filtration system and method utilize a filtration medium including steel slag. By improving or replacing a conventional filtration media, such as a sand filtration system, with a filtration medium including steel slag, the removal efficiency of suspended solids and affiliated pollutants is improved and the lifespan of the filtration system is lengthened.
