Sheinbaum floats possible environmental concerns with Arizona’s Mexico desalination plant proposal

Mexico’s president is calling for environmental studies of an Arizona proposal to build a desalination plant on the Gulf of California.

Late last year, an Arizona water agency voted to consider multiple options to increase the state’s supply — including a proposal to build a desalination plant on the Gulf of California.

A proposal a few years ago to pump desalinated water near Puerto Peñasco, Sonora, to Arizona was scrapped after concerns from the governor of Sonora.

Mexican President Claudia Sheinbaum pointed out at her daily morning press conference Wednesday that desalination plants, generally, can have environmental impacts.

“You take the salt out of the water, and then the problem is, what do you do with the salt?” Sheinbaum said.

She noted that returning the salt to the sea is one option and works in some cases, but said that could cause problems for the Gulf of California’s sensitive and biodiverse ecosystem. Those possible environmental impacts, she said, would have to be studied.
