Estimation of the vulnerability to saline intrusion of the coast of Hermosillo aquifer, Sonora, Mexico
Vulnerability of aquifers is evaluated with methods such as DRASTIC, AVI, GOD, EPIK, SINSTACS, where pollutants are added near the surface. Intrusion by seawater involves hydrogeologic characteristics completely different from those used in vertical vulnerability assessment. In northwestern Mexico,...

Intrusion by seawater involves hydrogeologic characteristics completely different from those used in vertical vulnerability assessment. In northwestern Mexico, coastal aquifers are heavily affected by high pumping rates. The coastal aquifer of Hermosillo has been intruded up to 32 km inland, and in some areas the water quality was degraded reaching EC of up to 40 000 J.lS/cm. In this study, the most vulnerable zones through which the seawater penetrates over the last 37 years are identified with the migration and position of the intrusion front. Vulnerability is studied in three risk zones: 1) Zone of high vulnerability due to tectonic subsidence, 2) Zone of medium vulnerability due to permeability of the aquifer, and 3) Zone of low vulnerability due to high gravimetric anomalies.La contaminación del agua subterránea tiene una amplia variedad de propagación ya sea fuentes puntuales o dispersas y su vulnerabilidad o el riesgo se han evaluado con métodos como DRASTIC, A VI, GOD, EPIK, SINTACS y otros, que poseen un común denominador, los contaminantes son adicionados sobre o cerca de la superficie del terreno. A diferencia de este mecanismo, la intrusión salina, o contaminación del agua dulce por agua de mar en acuíferos costeros, involucra características hidrogeológicas distintas de degradación. Ello obliga a usar metodologías más extensas, tardadas y a veces con alto grado de complejidad, pues el conocimiento de escenarios hidrogeológicos necesita de numerosas herramientas para la obtención de parámetros. En la costa noroeste del Pacifico mexicano, los principales acuíferos están gravemente afectados por sobrebombeo agrícola. El acuífero de la Costa de Hermosillo en Sonora ha sido intrusionado hasta 32 km tierra adentro; ello degrado la calidad del agua alcanzando conductividades eléctricas de hasta 40 000 J.lS/cm. Para conocer las zonas vulnerables por donde penetra diferencial y preferencialmente el agua de mar desde hace 37 años se actualizo el modelo hidrogeológico e identificaron la migración y posición del frente de intrusión utilizando la geometría del basamento, la hidroestratigrafía y propiedades del acuífero, obteniéndose a partir de ellas una clasificación de vulnerabilidad para tres zonas de riesgo: 1) Zona de vulnerabilidad Alta por subsidencia tectónica, 2) Zona de vulnerabilidad Media por permeabilidad del medio, 3) vulnerabilidad Baja definida por altos gravimétricos.Universidad Nacional Autónoma de México.
