Pierce Provides Cost-Effective Options to Ocean Desalination

Gregory Pierce, co-director of the UCLA Luskin Center for Innovation, wrote an article for The Conversation to discuss how desalination may not be the most viable option for creating a more sustainable water supply. In an effort to combat California’s record-setting drought, Gov. Gavin Newsom has announced an $8 billion plan to increase the state’s water supply. The plan includes methods like water conservation, storage, recycling and ocean desalination. Pierce explains how desalination creates more consequences than solutions as it kills aquatic life, pollutes ecosystems with brine and wastewater that can end up in the ocean, and poses a very high cost. He instead suggests conserving water, reusing treated wastewater which is cheaper than desalination, and increasing storage capacity even in places with infrequent rain to capture stormwater. “Even cleaning up polluted local groundwater supplies and purchasing water from nearby agricultural users, although these are costly and politically difficult strategies, may be prudent to consider before ocean desalination,” said Pierce.
