A local emergency services responder and SCUBA diving expert is working to rejuvenate a national diving organization that has moved from Florida to Freeport.

The group's first project will be the invitation-only premiere of a documentary on diving the wreck of the SS Cedarville in the Straits of Mackinac in Michigan.

Conrad Pfeifer, a longtime police officer in southern Butler County and executive director at Quality EMS in Adams Township, said the Cambrian Foundation was based for many years in Florida.

The foundation's mission is “research, education, preservation and exploration of the aquatic realm.”

Its members have explored the USS Monitor, the Edmund Fitzgerald before it was declared off-limits, World War II shipwrecks in Guadalcanal, and other sunken vessels.
