This paper presents the first results of a hidrogeochemical investigation in the Loa River basin (33.400 km2) in the Antofagasta Region, Northern Chile. The Loa River (440 km long) is the only permanent stream in this deserted region (Atacama Desert), with a flow of water ranging between 0.5 and 3 m3/s. High salinity and high levels of dissolved arsenic and boron made waters from Loa River not directly suitable for drinking water supply. The irrigation use is limited. In order to evaluate the present situation, water samples were taken at 13 strategic points along the Loa River and its mayor tributaries.

Abstract

This paper presents the first results of a hidrogeochemical investigation in the Loa River basin (33.400 km2) in the Antofagasta Region, Northern Chile. The Loa River (440 km long) is the only permanent stream in this deserted region (Atacama Desert), with a flow of water ranging between 0.5 and 3 m3/s. High salinity and high levels of dissolved arsenic and boron made waters from Loa River not directly suitable for drinking water supply. The irrigation use is limited. In order to evaluate the present situation, water samples were taken at 13 strategic points along the Loa River and its mayor tributaries.
