Résumé
Arsenic, a group A human carcinogen according to the International Agency of Research on Cancer, occurs naturally in tube-well water ranged from < 1 - 1630 µg/l. World Health Organization drinking water guideline for arsenic is < 10 µg/l. This study aimed to assess arsenic concentration and distribution in tube-well water in southern Burkina Faso. Samples were randomly collected and analyzed for arsenic by atomic absorption spectrometry in November 2010 and November 2014. Results from 6 cities show tube-wells arsenic concentrations ranged from 1.03-16.10 µg/l. At levels < 10 µg/l, arsenic is not considered to endanger health of exposed populations. However, other studies in Burkina Faso found As >10µg/l, resulting in the closure of a number of tube-wells ; reducing access to drinking water supply in rural areas. The public health implication of well closure may be greater than continued use of groundwater with As > 10 µg/l.
