To reduce exposure to arsenic, a common mitigation strategy for s is to switch from a contaminated shallow tubewell to nearby low-arsenic shallow tubewells (Ahmed et al., 2006; Van Geen et al., 2002). However, recent studies have shown that groundwater pumped from shallow low-arsenic wells is more likely to be contami-
