A treatment media, system, and method are disclosed which combines adsorptive capacity of a carbon media (e.g., biochar) with chemical treatment characteristics of a red mud substance, e.g., to remove metals and/or other contaminants from waters. The treatment media may also improve biological conditions of affected soils. In an example treatment method, a lignin based material is thermo-chemically decomposed to have a large weight fraction of carbon (e.g., the biochar), and an ore is processed to yield aluminum oxide comprising a variety of iron oxides and having high alkalinity in slurry (e.g., the red mud). The thermo-chemically decomposed lignin based material is combined with the mud material.

1. A treatment media comprising: a red mud fraction having a density of greater than approximately 3.4 g/cm3; anda biochar fraction having a specific density of less than approximately 1 g/cm3. 2. The treatment media of claim 1, wherein the red mud fraction further comprises a plurality of metal oxides. 3. The treatment media of claim 1, wherein the media binds with at least one of Al, Cd, Cu, Fe, Pb, Mn and Zn. 4. The treatment media of claim 1, further comprising a mass ratio of approximately one part biochar fraction to one part red mud fraction. 5. The treatment media of claim 1, further comprising a mass ratio of approximately two parts biochar fraction to one part red mud fraction. 6. The treatment media of claim 1, wherein the biochar fraction and the red mud fraction is proportioned to reduce total concentrations of Al, Cd, Cu, Fe, Pb, Mn and Zn, from contaminated waters. 7. The treatment media of claim 1, wherein the biochar fraction and the red mud fraction is proportioned to neutralize pH of acid mine drainage waters. 8. The treatment media of claim 1, wherein the biochar fraction has an average diameter greater than about 2 mm and less than about 4 mm. 9. The treatment media of claim 1, wherein the biochar fraction and the red mud fraction is proportioned to reduce metal concentrations until both the adsorptive capacity of the biochar fraction and surface reactivity of the red mud fraction are exhausted. 10. The treatment media of claim 1, wherein the biochar fraction and red mud fraction is proportioned to strongly bind with heavy metals and reduce reintroduction into waterways. 11. The treatment media of claim 1, configured as a vegetative cover for application to soils contaminated with heavy metals. 12. The treatment media of claim 1, wherein the biochar fraction is thermo-chemically decomposed to provide a lignin based material with a carbon weight fraction of at least 80%. 13. The treatment media of claim 1, wherein the red mud fraction is pre-washed. 14. The treatment media of claim 1, wherein the biochar fraction and the red mud fraction are combined by at least mechanical mixing.
