On the heels of an Investigative Fund story in Mother Jones last week that found that Starbucks sources its bottled water from a spring in the heart of California’s drought country, Starbucks announced yesterday that it will phase out use of its California bottling plant for Ethos Water over the next six months. Because of “the serious drought conditions” in California, the company will transition to its Pennsylvania supplier while looking for another source to cover the western United States, Starbucks officials said in a press release.

The California counties from which Starbucks sources and bottles Ethos have been in a drought emergency for years now. Placer County, where Ethos’ spring water is drawn, was already declared a natural disaster area by the USDA because of the drought back in 2012. Reports from more than a year ago noted that the county was already scrambling to deal with the area’s “extreme drought.” Merced County, where the bottling facility is located, declared a local emergency due to drought more than a year ago, as “extremely dry conditions have persisted since 2012.”

Meanwhile, the Pennsylvania county to which Starbucks is now shifting its entire national production of Ethos Water is itself facing drought conditions. While not as catastrophic as California’s historic water emergency, Luzerne County, where Starbucks’s east coast supplier sources and bottles Ethos, was declared to be under Drought Watch by Pennsylvania’s Department of Environmental Protection back in March. DEP issued the declaration after below-normal rainfall over the past year has led to low groundwater levels in the region, which the agency noted has the potential to cause well-fed water supplies to go dry. The state is asking local residents to voluntarily reduce water consumption and to “run water only when absolutely necessary.” DEP has put large water users on notice to plan for possible reductions in water supplies.

Nevertheless, Ethos’s Pennsylvania bottler, Nature’s Way Purewater, which bottles a number of other brands at its facility, announced in January that it planned to double production going forward.
