This briefing describes a June–July 2013 mesocosm experiment testing biochar-based adsorptive media in gravity filters and three natural-channel-structure designs (rock drop, log habitat, glide) on South River water. Lab-scale biochar filters removed most dissolved mercury and reduced periphyton methylmercury accumulation by ~46%; structure housings showed no reduction, likely due to low contact time.
