Abstract
The Czech Geological Survey has been conducting geological mapping on the scale 1:50,000 in several areas of Nicaragua and El Salvador since 1997. In 2004, an area of approximately 750 km2 was studied in the northern parts of the La Libertad, San Salvador, and Cuscatlán districts in El Salvador from the perspective of geological hazards and hydrogeology. A basic description of the water cycle conditions and ground water units of this area were made for the first time, including the study of infiltration zones, transit zones, and zones of drainage. A 1:50,000 scale hydrogeological map, and a vulnerability map for one selected drainage area of the Río Matizate river were designed. The basic hydrogeological conditions, hydrochemical groundwater characteristics, the potential for groundwater contamination, and the main sources of pollution were also described.
