Arsenic removal in water by oxidized aquifer material achieved through passive air exposure (AE) and oven-dried (OD) aquifer samples. Arsenic loss (%) was calculated ([As]INITIAL - [As]FINAL)/[As]INITIAL) × 100) and based on samples collected 68 days after the arsenic solution ([As]INITIAL = 550 μg/L) was amended to the test reactors. All samples (replicates) in AE and OD reactors were non-detect (detection limit = 5 μg/L).
