Investigating Pollution

Baykeeper patrols the Bay and investigates pollution

Baykeeper is the only organization that patrols San Francisco Bay to investigate and stop pollution.

We regularly patrol the Bay on the Baykeeper boat, and by plane, kayak, and with our drone, Osprey. Our scientists identify threats to the Bay and gather evidence of pollution and investigate tips from the public to our Pollution Hotline.

And when we find pollution, our advocates and lawyers take action to hold the polluters accountable and stop them from harming the Bay and the people of the Bay Area.
