Article Abstract:

Arsenic concentrations found in Vietnamese groundwater wells are measured at toxic levels. The source of contamination is described as an oxyhydroxide reduction process exacerbated by the tropical environment, and ingestion by humans is attributed to the prevalence of UNICEF-built tubewells that tap directly into arsenic-contaminated waters.
