Regenesis – Alameda Point Environmental Report

PFAS contamination successfully blocked from entering Oakland Estuary

On July 23, 2025, the Navy released the results of its pilot study to determine if injecting a specialized carbon solution into the ground would block hazardous PFAS chemicals from migrating into the Oakland Estuary from Alameda Point.

The area at issue, a stone’s throw from the estuary, had once been used by Navy firefighters to practice putting out fires with firefighting foam that contained PFAS chemicals. Scientists have figured out a way to contain, but not destroy, these hazardous chemicals. Follow-up groundwater samples show that the carbon barrier achieved between 99 percent and 100 percent reduction in PFAS moving beyond the barrier.

PFAS remediation work underway next to Alameda Point shoreline

In late June, a Navy contractor began the month-long process of injecting over 180,000 gallons of activated carbon solution into the ground at Alameda Point to prevent a hazardous substance called PFAS (Perfluoroalkyl and Polyfluoroalkyl Substances) from entering the Oakland Estuary.
