The aquifer that supplies water to Mexico City could be recharged in eight areas, according to a new university research study.
“There are conditions favorable to groundwater recharge in numerous sites, which is an important factor for integrated water management,” researcher Víctor Díaz of the School of Engineering at the National Autonomous University of Mexico told Tierramérica.
Díaz is the author of the report “Representación cartográfica del cambio climático” (Climate Change Mapping), which assesses the water supply situation in the Mexican capital, home to 8.8 million people.
The aquifer is seriously overexploited, given that 40 cubic meters of water per second (m3/s) are extracted while the recharge rate is only 19 m3/s. Precipitation contributes 216 m3/s, but 37 m3/s are lost through drainage.
