A diagnostic survey was carried out of the groundwater in the southeast subhumid pampa of Argentina in order to determine the presence, spatial distribution, and concentration of fluoride. The area studied extends along the southeastern border of the pampa plains between latitude 3818' and 3858' S and longitude 6043' and 6143' W, covering an irregular surface area of approximately 6000 km2. The region has a large rural and suburban population that relies on this groundwater as its principal source of water for human consumption and for use in agricultural and livestock production. The variation in fluoride content in the groundwater is illustrated on maps of the area, showing that the whole region is affected by this ion contaminant. In 97.1% of the samples fluoride values exceeded the limits recommended by the Argentine Food Code for human consumption and indicated that the use of the water in livestock should be restricted. The quality of the water for irrigation purposes also was seriously affected. Critically affected zones were identified with a view to implementing public health measures to protect against this highly contaminated resource. 2003 Wiley Periodicals, Inc.
