Abstract

This paper presents an overview of natural geochemical processes that can mobilize arsenic (As) from aquifer sediments into groundwater. The primary source of As in groundwater is pre-dominantly natural (geogenic), and can be mobilized via complicated biogeochemical interactions within various aquifer solids and water. Oxidation of sulfide minerals such as arsenopyrite, As-substituted pyrite and other sulfide minerals are susceptible to oxidation in near surface environment, and release significant quantities of As from sediments. Reductive dissolution of As-bearing Fe(III) oxides/hydroxides 2and sulfide oxidation are the most common and significant geochemical triggers that tend to release As from aquifer sediments into groundwater. Hence, strengthening direct action and implementation of the best practices to target the safe groundwater sources for installing safe drinking water wells are an urgent necessity for sustainable As mitigation on a global scale.
