Treasure Island Naval Air Station

Naval Station Treasure Island is a former United States Navy facility that operated on Treasure Island in San Francisco Bay from 1942 to 1997.
Three wells were tested at the Navy’s old Treasure Island Naval Station and three were found to be poisonous.
PFOS/PFOA were found in the groundwater at 10,750 ppt, many times over the EPA’s Lifetime Health Advisory of 70 ppt.

Treasure Island, the former naval base, is being transformed into a $6 billion development of condos and shops. It was once considered hazardous enough to be a federal Superfund waste site but was never officially named one, newly disclosed documents show. https://www.sfchronicle.com/bayarea/article/SF-s-Treasure-Island-poised-for-building-boom-14451339.php?psid=nKnJm#photo-18286303 |
