San Francisco Baykeeper defends the Bay and its watershed from the biggest threats. We hold polluters and government agencies accountable to create healthier communities and help wildlife thrive.

Our field science team patrols the water by boat and drone to investigate pollution; our advocates strengthen laws and close loopholes to protect the Bay’s wildlife and communities; and our attorneys take on multinational corporate polluters and government agencies at all levels.

We've used this unique and effective combination of investigation, advocacy, and litigation since 1989.
