How Much Lithium (for EVs) is Sitting in PA Marcellus Brine?

In October 2019, Eureka Resources, which operates three frack wastewater treatment facilities in the Marcellus Shale (and is building a fourth facility in Dimock, PA), began extracting lithium from Marcellus wastewater at one of its plants in Bradford County, PA (see Marcellus Wastewater Plant in PA Extracts 1st Batch of Lithium). In 2020, the company said its plants could theoretically supply up to 25% of the country’s annual lithium demand–solely with lithium recovered from Marcellus wastewater (see Eureka Can Supply 25% of US Lithium Demand from Marc. Wastewater). Just how much lithium, theoretically, is there in Marcellus brine (wastewater)? A new study published this week on the Nature.com website helps answer that question.
