“…Water consumption has increased over the last few decades, causing a water table decline of the main aquifer of approximately 1Ð0-1Ð4 m year 1 (Osuna-Viscarra, 1991;CNA, 2001). Water table drops due to increasing groundwater consumption are a common problem in the aquifers of central and northern Mexico (Brouste et al, 1997;Edmunds et al, 2002;Mahlknecht et al, 2004Mahlknecht et al, , 2006aEsteller and Andreu, 2005;Portugal et al, 2005;Daessle et al, 2006;Flores-Marquez et al, 2006;Schoups et al, 2006;Ramos-Leal et al, 2007).…”

Abstract:The Chihuahua City region, located in the semiarid-arid northern highlands of Mexico, has experienced intensive groundwater abstraction during the last 40 years to meet water demands in the region. A geochemical survey was carried out to investigate the evolution from baseline to modern conditions of a 130-km flow path including the El Sauz-Chihuahua-Aldama-San Diego de Alcalá regions. The research approach included the use of major chemical elements, chlorofluorocarbons and environmental isotope ( 18 O, 2 H, 13 C and 14 C) tracers. Stable isotopes indicate that groundwater evolves from the evaporation of local rainfall and surface water. Groundwater located at the lower end of the flow section is up to 6000 years old and older groundwater in the order of 9000 years BP was found in a deep well located in the upper part of the flow system, implying contribution from a neighbour basin. The background groundwater chemistry upstream of Chihuahua City results from feldspar weathering. Beyond Chihuahua City the chemical conditions are strongly modified owing to disposal of sewage from public and industrial water supplies into the Rio Chuviscar, subsequent allocation of this water to agricultural irrigation areas and direct infiltration under the river bed. As a consequence, anions like chloride and sulphate are mainly related to surface sources. Nitrate is controlled in part by sewage from public supply and industry and in part by agricultural practices. Arsenic and fluoride are related to weathering of rock formations of local mineralized ranges and subsequent enrichment of the basin-fill by magmatic processes. The results of this study have implications for groundwater management in an arid region that depends entirely on groundwater for domestic, industrial and agricultural water consumption.

“…Groundwater from the nearby aquifers is the main source for Maneadero and Guadalupe irrigation. From 28 to 32 Mm 3 /yr of water are extracted from the Guadalupe aquifer, supplying roughly one third for potable water supply for the city of Ensenada and twothirds for agriculture in the Guadalupe valley, which supports the most important wineries in the country (Daesslé et al, 2006;Mendoza-Espinosa et al, 2008). Despite the economic importance of agriculture in these three areas, urban uses continue to expand.…”

“…El acuífero del Valle de Guadalupe constituye la única fuente de agua, para la industria vinícola más importante de México (Daesslé et al, 2006). En la región se encuentran al menos 27 bodegas establecidas, que producen alrededor de 50 marcas de vino reconocidas, a las que se suman más de 80 vinos artesanales elaborados por productores menores.…”

ParadeterminarelefectodelacalidaddelaguaenelAcuífero del Valle de Guadalupe, Baja California, México, en la salinidad de los suelos agrícolas se midió el pH, conductividad eléctrica, sólidos disueltos totales y la concentración de los principales iones en las aguas de 66 pozos, de un total de 754 que se encontraban en operación en el acuífero durante 2009. Y se analizó en el extracto de pasta de saturación de muestras de suelo el pH, conductividad eléctrica, carbonato, bicarbonato, cloruro, sulfato, boro, fósforo, nitrato, calcio, magnesio, sodio, potasio, amonio. El 74% de los suelos estudiados presenta una cantidad superior a 15 mg kg-1 de nitratos, y por tratarse de suelos arenosos se atribuyen problemas de contaminación a las aplicaciones de fertilizantes nitrogenados. La salinidad del agua está presente en todo acuífero del Valle de Guadalupe (clasificada como C3 y C4 en 85.9%), pero la salinidad del suelo (pHpromedio= 7.6) no se presenta en el total de la superficie del valle; por lo tanto el agua del acuífero no es la única causante de dicho problema, el manejo del agua para riego y la aplicación de fertilizantes deben ser estudiados para cuantificar su contribución a la salinidad del suelo.
