Controls on selenium distribution and mobilization in an irrigated shallow groundwater system underlain by Mancos Shale, Uncompahgre River Basin, Colorado, USA
Abstract
Groundwater Se concentrations ranged from below detection limit (<0.5μgL(-1), and primarily are controlled by high groundwater nitrate concentrations that maintain oxidizing conditions in the aquifer despite low dissolved oxygen concentrations, which indicate nitrate is largely derived from natural sources in the Mancos Shale and alluvial material.
