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.

Knowledge graph centered on Controls on selenium distribution and mobilization with 7 nodes and 13 connections. Top connected: Mobilization of selenium from the Mancos Shale and, Nitrogen and carbon flow from rock to water: Regul, Judith Thomas, Gabrielle Keith, M. Alisa Mast.
