Abundance and distribution of fluoride concentrations in groundwater: La Ballenera catchment, southeast of Buenos Aires Province, Argentina

High concentrations of fluoride have negative effects on human health, and it is one of the most widespread contaminants in groundwater, having being found in high concentrations in different countries over the entire world. Fluoride concentrations exceeding the drinking water levels are very freque...
