In Nicaragua, arsenic is of geogenic nature and has been detected in the whole territory ranging from 0.99 to 1320 g Ast/L in drinking water supply exceeding the standards for human intake. Arsenic speciation [As(III), As(V)] is unknown, deriving concern into the population located close or in the foothills from the volcanic mountain range of Los Maribios, whom are being affected with arsenicism, diabetes and kidney problems related to the high concentrations of this metalloid. Understanding of the processes controlling the mobility, speciation, distribution and transport of the arsenic in the active volcanic zones is of high relevance to determine arsenic safe water zones, safeguarding human health, improving the livelihood and economic development of approximately 102,105 inhabitants.
