Anomalous high fluoride concentration up to 7.59 mg/dm3 is found in groundwater from “La Victoria” area. This water is used to supply drinking water to Hermosillo City, Sonora. Geochemistry of groundwater, relationship between physicochemical parameters, hydrogeology and geologic setting were correlated to define the origin and the geochemical mechanisms of groundwater fluorine enrichment. High fluoride...
The exceeding brines of Cerro Prieto Geothermal Field (CPGF) are disposed into a lagoon and part of them infiltrate into the upper aquifer. This work describes the geochemical processes of how geothermal brine reaches the soils to the south and southwest of CPGF according to local flow lines from piezometric measurements. Soil and groundwater samples were collected and analyzed in the CPGF and the...
