The current study examined the use of a ZVI (zero valent iron)/sand filter for the removal of arsenic (As) from Canadian Prairie ground water sources Batch isotherm data indicated a favourable reaction represented by the Langmuir isotherm equation with loading capacities of 5000 and 2000 mg As/kg ZVI Column experiments using arsenate-spiked RO water (50 mu g/L) and varying volumetric ratios of ZVI to sand indicated no statistical difference in arsenic-removal performance above a ZVI/sand ratio of 20/80 (%, v/v) with removal efficiencies of greater than 98% A second column study using two ground water sources with 50/50 and 40/60 ZVI/sand filters achieved 89 - 96% As removal
