Abstract

En 中文

• Localized redox state due to confining clay layers lead to release of redox-sensitive geogenic contaminants (As & Ni). • Local aquifer heterogeneity dictates geogenic contaminants (As & Ni) risk. • Hydrostratigraphic delineation should guide safe community drinking water sources.
