Summary

This book covers the occurrence of arsenic in groundwater, mobility constraints, water-sediment interactions, themes concerning aqueous geochemistry of arsenic in sedimentary and hard rock aquifers, natural environmental systems assessment of environmental health risks and economic impacts, and arsenic removal technologies. It aims to create interest within countries affected by arseniferous aquifers; update the status of knowledge on the dynamics of natural arsenic from the aquifers through groundwater to food chain; explain efficient techniques for arsenic removal; inform administrators, policymakers, and executives; and increase awareness of natural arsenic occurrences.
