The range of As concentrations found in natural waters is large, ranging from less than 0.5 μg l−1 to more than 5000 μg l−1. Typical concentrations in freshwater are less than 10 μg l−1 and frequently less than 1 μg l−1. Rarely, much higher concentrations are found, particularly in groundwater. In such areas, more than 10% of wells may be ‘affected’ (defined as those exceeding 50 μg l−1) and in the worst cases, this figure may exceed 90%. Well-known high-As groundwater areas have been found in… Expand
Arsenic distribution, concentration and speciation in groundwater of the Osijek area, eastern Croatia
Abstract Groundwater is the main source of drinking water for the population of nearly 200,000 people in eastern Croatia. The largest town in the region is Osijek whose citizens are supplied withExpand
Arsenic and Other Metal Contamination of Groundwaters in the Industrial Area of Thessaloniki, Northern Greece
TLDR
Findings emerge the problem of contamination from arsenic, since, according to the EU directive 98/83, all drinking water sources within the European Union should have achieved compliance with the new limits by 12/2003, implying that the situation requires urgent remedial action. Expand
Contamination by arsenic and other trace elements in tube-well water and its risk assessment to humans in Hanoi, Vietnam.
TLDR
It is revealed for the first time that the residents of Gia Lam and Thanh Tri Districts are exposed not only to As but also Mn and Ba from groundwater in the Red River Delta, Vietnam. Expand
Partition of arsenic in soils sediments and the origin of naturally elevated concentrations in groundwater of the southern pampa region (Argentina)
Excessive arsenic concentrations above the Argentinean and WHO guidelines for drinking water (10 μg L−1) affects shallow aquifers of the southern Pampean Plain (Argentina) hosted in the Pampean andExpand
Controls on elevated fluoride and arsenic concentrations in groundwater from the Yuncheng Basin, China
Chemical analysis of groundwater and sediments was carried out to investigate causes of elevated F(-) (1.5-6.6 mg/L) and As concentrations (10-27 mu g/L; one sample affected by local contaminationExpand
Arsenic in groundwater in the southern lowlands of Nepal and its mitigation options: a review
As in several other countries of Southeast Asia (namely Bangladesh, India, Myanmar, China, Vietnam, and Cambodia) arsenic (As) concentrations in the groundwater of the lowlands of Nepal (the soExpand
Remarks on the current quality of groundwater in Vietnam

This paper reviews the current quality of groundwater in Vietnam. In Vietnam, groundwater is obtained primarily from tubewells, which have high concentrations of pollutants such as As, Fe, Mn, andExpand
DISTRIBUTION OF ARSENIC IN GEOTHERMAL WATERS FROM SABALAN GEOTHERMAL FIELD , NW
Distribution of Arsenic in geothermal waters in Sabalan area has been studied. In all samples concentration of As exceed the WHO limit for drinking water (10 μg/l) except one sample from Agh-su hotExpand
Co-occurrence of arsenic and fluoride in the groundwater of Punjab, Pakistan: source discrimination and health risk assessment
TLDR
It is proposed that pollutants originate, in part, from coal combusted at brick factories, and agricultural activities, and once generated, these pollutants were mobilized by the alkaline nature of the groundwater. Expand
The origin of arsenic in soils and groundwater of the Pannonian part of Croatia
Arsenic content in surface layer (0-25 cm) varies from 0.9 mg/kg soil to almost implausible 490 mg/kg. The reason for the highest content in hydromorphic soils should probably be sought in recentExpand

The oxidation states of arsenic in well-water from a chronic arsenicism area of northern Mexico.
TLDR
It is suggested that periodic studies be performed on the As(III)/As(V) ratio in wells whose total As concentrations are above 0.05 mg litre(-1), in combination with epidemiological studies to evaluate possible differences in health effects produced by different As species. Expand

Inorganic arsenic species in groundwater: a case study from Purbasthali (Burdwan), India.
TLDR
Speciation studies indicate that As(III) is present in only one sample and organo-arsenic compounds have not been detected, and the pH value of the groundwater in this area shows that it is more or less neutral. Expand
