Injection into the shallow aquifer-aquitard system beneath Mexico City for counteracting pore pressure declines due to deeper groundwater withdrawals: Analysis of one injection well

Abstract: Los acuíferos están siendo severamente sobre-explotados en muchas partes del mundo conforme al continuo aumento de las poblaciones urbanas. Además, la excesiva extracción del agua subterránea de los acuíferos ha acelerado dramáticamente la consolidación de los acuitardos sobre-yacientes, creando severos hundimientos del terreno y muchos otros problemas relacionados. La Ciudad de México, con una población de 20 millones de habitantes y un acuífero principal exhausto, es un sitio que ofrece excelentes condicione… Show more

“…CDMX is underlain by an extensive plain of low‐strength, very compressible, lacustrine‐clayey aquitards partially overlain by highly productive aquifers of volcanic and sedimentary origin (Vázquez‐Guillén & Auvinet‐Guichard, 2019). The region relies heavily on groundwater resources for more than 70% of the total water consumption, causing extraction of at least ∼53 m 3 /s, significantly exceeding the natural recharge of ∼20 m 3 /s, and causing a steady groundwater level decline of 1.0–1.5 m/yr (Palma Nava et al., 2022).…”

“…Notably, the accuracy of PREM reduces in the Earth's outermost 50 km due to the heterogeneity of the crust and the uppermost mantle (D'Urso & Marmo, 2013; Dill et al., 2015). Here, we examine two sets of half‐space Green's functions characterized by endmember Young's modulus of 6 and 50 MPa as lower and upper bounds, consistent with local geology and subsoil beneath Mexico City, which is dominated by fine‐grained material, mostly silt and soft clay with lenses of sand, gravel, and hard clay (Vázquez‐Guillén & Auvinet‐Guichard, 2019).…”
