Established in 1705, the town of Groton is geographically located between the Thames and Mystic Rivers in the southeastern corner of Connecticut. The town is comprised of eight separate subdivision communities that are referred to as fire districts. Groton is also the home to a large naval submarine base, a small general aviation airport, and several major industrial facilities, including the Electric Boat Corporation and Pfizer, Inc. The Mystic fire district is recognized for its historical maritime museums and facilities and plays host to thousands of tourists each year. At the present time, Groton and Mystic are provided emergency services by 13 fire departments, three police departments, two ambulance associations, one paramedic response unit, and one central dispatch operation.
