US Navy Acknowledges Rising Toxic Groundwater Threat at SF Superfund Site

The U.S. Navy has acknowledged that in just over a decade, potentially toxic groundwater could surface at a Superfund site at Hunters Point Naval Shipyard in San Francisco. The report comes as the city plans to build thousands of homes, retail, and over 340 acres of parks and open space at a highly complex and ongoing cleanup effort. When finished, the 693-acre Candlestick Point-Hunters Point Shipyard project — which the Superfund site is part of — could have more than 10,000 housing units.  The soil at the site, where the Navy used to decontaminate ships after atomic bomb tests, contains radionuclides, heavy metals and petroleum fuels, among other toxic compounds. Despite interventions designed to keep contaminants immobile, sea level rise and ground water rise are future threats. Learn more in this article: by Ezra David Romero for the KQED Science Report.
