High arsenic (As) groundwater has been found in Pliocene confined aquifers at depths from
100 to 300 m of the Guide basin, but little is known on the main hydrogeochemical …

Groundwater contamination with arsenic and fluoride has affected over 300 million people
worldwide. Ingestion of arsenic and fluoride for extended period of time or at high …

The competitive sorption of carbonate and arsenic to hematite was investigated in closed-
system batch experiments. The experimental conditions covered a pH range of 3–7 …

Drinking water supply for the Main Ethiopian Rift (MER) area principally relies on
groundwater wells and springs and is characterized by natural source of elevated fluoride …

Extremely high As concentrations in drinking water of the Ganges Delta (West Bengal and
Bangladesh) has emerged as an issue of great concern in the past decade because of its …

This review is focused on the biogeochemistry of arsenic in freshwaters and, especially, on
the key role that benthic microalgae and prokaryotic communities from biofilms play together …

A review of published information on the arsenic contamination of groundwater in the Terai
regions of Nepal showed that the source was mainly geogenic due to the dissolution of the …

The spatial variability of As concentrations in aquifers of the Red River Delta, Vietnam, was
studied in the vicinity of Hanoi. Two sites, only 700m apart but with very different As …

The objective of this study is to analyze the geochemical conditions associated with the
presence of arsenic (As) and fluoride (F) in the phreatic aquifer of Coronel Moldes, in the …

Abstract At Jianghan Plain of central Yangtze basins where the health of> 73, 000 people
has been affected by long term intake of high arsenic groundwater, over 100 sediment …
