61 mg L-1 Al3+) and from the AM ( 52 mg L-1 Mn2+). Vermiculite used to remove these cations adsorbed about 86% Al3+ and 90% Mn2+. However, only Al3+ concentrations fell below the standard limit for drinking water of less then 0.5 mg L-1. Therefore, AA has the advantage of not containing Mn, and after 3 h kept F- concentrations in solutions 5 mg L-1F- below the standard limit of 1.5 mg L-1. This study revealed that, depending on the groundwater characteristics, AA may be more efficient and sustainable for defluoridation than coa
