This series of maps shows the enrichment, geoaccumulation, potential ecological risk, and distribution of metals results in the Aguada Blanca Reservoir in southern Peru. This reservoir is the main source of drinking water for more than one million people in the city of Arequipa. It can be observed that most of the elements present an increase in their concentrations as they approach the reservoir outlet, which could indicate water quality problems due to inappropriate sediment removal in the last 30 years.
