The study reviews the challenges waterresources management faces, and the opportunities for policyformulation towards sustainable development in Argentina,where regardless of prudent public finances management,water resources management remain disproportionatelybackward compared to regional, and international bestpractices. Hence, within a frame of reference on thecountry's population, institutions, and legalframework, the study examines the current, accelerateddegradation of water quality, where arsenic and nitratepollution are found in groundwater, a main source ofdrinking water supply in some rural areas, aggravated by theuncontrolled dumping of raw wastewater in urban areas. Theuses, and management of drinking water, and sewage areanalyzed, revealing eighty-one percent of urban populationsare connected to drinking water networks, and onlythirty-eight percent to sewer networks. Upon review of theirrigation sector, which accounts for seventy percent of allextractions of water consumption uses, the study shows verylow levels of efficiency, compared to similar experiences inother countries. Integrated and modern water management issuggested, and recommendations include: preservation ofgroundwater resources; promotion of policies, and actions tocontrol surface water pollution; increased coverage toreduce toxicity risks in drinking water; and, modernizationof sanitation, and irrigation systems.
