Disclosed is a heavy metal removal media containing ferric hydroxide having unique levels of microporosity and mesoporosity/macroporosity, and/or a specific average particle size and/or granule size. The ferric hydroxide is made by simultaneously combining in a vessel at least one iron salt and at least one hydroxide compound, and then recovering the ferric hydroxide. The ferric hydroxide made by simultaneous mixing is effective in removing heavy metals, such as arsenic, from aqueous systems.
