Argentina Blindly Exploiting Groundwater

“According to the Environmental Atlas of Buenos Aires, the depth of the Puelches aquifer ranges from 40 to 120 metres, and it supplies 9,900 cubic metres of water a day. It is located between the Pampeano aquifer, which is closer to the surface, and the deeper Paraná aquifer, whose water is salty and used primarily by industry.

In the eastern region of the country are the Ituzaingó, Salto and Salto Chico aquifers. And in the province of Neuquén, in the western part of the southern region of Patagonia, groundwater reserves provide water for the oil, gas and mining industries, explained Mario Hernández, a hydrogeologist from the National University of La Plata.

There are also aquifers in the southern province of Santa Cruz. And in the northwest, an arid region with little rainfall, these groundwater deposits are recharged by river water.

In the western provinces of Mendoza and San Juan, water is supplied primarily by underground reserves. As a result, the aquifers here are studied and protected, and subject to regular monitoring, because the local wine industry depends on the water they provide.

“Groundwater resources play a key role in arid and semi-arid regions. If it weren’t for the aquifers, massive engineering works would be needed to supply water for irrigation or residential use,” Tujchneider told Tierramérica.”
