Water resources management in El Salvador is characterized by difficulties in addressing severe water pollution throughout much of the country's surface waters due to untreated discharges of agricultural, domestic and industrial run off. The river that drains the capital city of San Salvador is considered to be polluted beyond the capability of most treatment procedures. Fortunately, El Salvador has ample groundwater and partly relies on these supplies for domestic purposes. Deforestation has ravaged the country to the point that very little primary forest remains. This has led to substantial difficulties in managing stormwater when hurricanes and tropical storms make landfall. Torrential rain leads to deadly floods and mudslides that have claimed many lives in El Salvador. A growing urban population coupled with high levels of water losses in urban centers is also challenging water institutions that are not well coordinated. This leads to inefficient water resources management.
