Mare Island - Former Naval Shipyard
The Mare Island Naval Shipyard was the first US Navy base established on the Pacific Ocean. It is located 25 miles northeast of San Francisco in Vallejo, California. The Napa River goes through the Mare Island Strait and separates the peninsula from the main portion of the city of Vallejo. The base made a name for itself as an important US West Coast submarine port. The base closed in 1996. The photo is from 1946.

Mare Island is identified as a DOD installation with known or suspected releases of PFOS/PFOA, according to a DOD Report to Congress on Aqueous Film-Forming Foam - Nov. 3, 2017.
No testing results were made public regarding the base, only that it is likely contaminated with the ”forever chemicals.”
