Increasing concern over environmental problems and the passage of more stringent legislation have led utility personnel to recognize that risk communication must become a part of their overall approach to environmental management. The key to effective risk communication is the two-way exchange of information between the utility and the public. The utility explains technical data to interested segments of the public, who in turn voice their concerns, opinions, and reactions. As well as being involved in a dialogue concerning the nature of the risk, the public should also be involved in decisions relating to its control. This article discusses general objectives, identifying the audience and its concerns, risk perception, designing messages, selecting communication channels, and evaluating the program.
