Seasonal effects in arsenic levels in drinking water in the Lagunera region

Abstract

Changes in arsenic content in the drinking water in the Lagunera Region in northern Mexico are presented here. Arsenic and water conductivity were measured both before and after the yearly irrigation cycle and also before and after a river bed that is usually dry, received water in a 2010, a wet year. The results were processed with a Geographic Information System (GIS) to understand better the changes in relation to the dry riverbed. The present work can evolve towards a real-time, sensor-based system.
