Contact Chief Atchison . . .
I believe that fire departments have taken over the role of the earlier civil defense dive team. I would recommend that you direct your question to the Chester Fire Department.
You can reach Chief Milton Atchison at:
Chester Fire Department
1330 Swanwick Street
Chester, IL 62233
You might also contact the Illinios Fire Chiefs Association at 800-662-0732. Jerry Burke is the Executive Director.
