Working with EPA divers

Our divers primarily support EPA's programs, but we also participate in joint diving activities under formal *reciprocity agreements* with a variety of organizations, including other federal and state agencies, universities, and private sector groups.

If your agency or organization is interested in conducting a joint diving project with EPA, please contact the Unit Diving Officer nearest you in the list above.
