“…Most of the exploited aquifers within the basin are unconfined, with the exception of the semiconfined aquifer of Toluca Valley [ Calderhead et al ., , Davila‐Hernandez et al ., ]. Their thickness typically ranges from 60 to 200 m (see an overview of the different aquifers in Castellazzi et al .…”

Groundwater deficits occur in several areas of Central Mexico, where water resource assessment is limited by the availability and reliability of field data. In this context, GRACE and InSAR are used to remotely assess groundwater storage loss in one of Mexico's most important watersheds in terms of size and economic activity: the Lerma-Santiago-Pacifico (LSP). In situ data and Land Surface Models are used to subtract soil moisture and surface water storage changes from the total water storage change measured by GRACE satellites. As a result, groundwater mass change time-series are obtained for a 12 years period. ALOS-PALSAR images acquired from 2007 to 2011 were processed using the SBAS-InSAR algorithm to reveal areas subject to ground motion related to groundwater over-exploitation. In the perspective of providing guidance for groundwater management, GRACE and InSAR observations are compared with official water budgets and field observations. InSAR-derived subsidence mapping generally agrees well with official water budgets, and shows that deficits occur mainly in cities and irrigated agricultural areas. GRACE does not entirely detect the significant groundwater losses largely reported by official water budgets, literature and InSAR observations. The difference is interpreted as returns of wastewater to the groundwater flow systems, which limits the watershed scale groundwater depletion but suggests major impacts on groundwater quality. This phenomenon is enhanced by ground fracturing as noticed in the field. Studying the fate of the extracted groundwater is essential when comparing GRACE data with higher resolution observations, and particularly in the perspective of further InSAR/GRACE combination in hydrogeology.In Mexico, groundwater fulfills more than 70% of the water needs for the 120 million inhabitants [Instituto Nacional de Estad ıstica y Geograf ıa, 2015]. Annual rainfall rates show a smooth transition from high Key Points: InSAR and GRACE observations are compared with the groundwater management scheme Discordance between GRACE, InSAR, and water budgets suggests important wastewater recharge Cointerpreting GRACE and InSAR brings an unprecedented insight into groundwater sustainability Correspondence to: P.

“…Many studies have shown that groundwater exploitation can cause an aquifer system to have reduced pore water pressure (Holzer and Johnson 1985;Woldai et al 2009;Calderhead et al 2010). As a result, the aquifer becomes compressed and ground subsidence occurs.…”

“…Mexico City is one of the World's most known land subsidence case, while other cities in Mexico are still poorly studied. Differential InSAR (D-InSAR) has been used to reveal groundwater overexploitation in Toluca valley [8,9]. Recently, Persistent Scatterer Interferometry (PSI) was applied to Mexico City [10].…”
