Kevin McCauley, editor for PR trade publication O'Dwyer's PR, calls on General Electric CEO Jack Welch to dredge up the company's PCBs in the Hudson River. Welch has adamantly opposed GE cleaning up the Hudson and denied a relationship between exposure to PCBs and cancer. The company has had success in creating opposition to dredging by bankrolling PR and ad campaigns. However, McCauley says, GE could get a big image boost "if Welch switched course and said: 'GE wants to be the country's No. 1 environmental citizen. We will dredge the Hudson River.'"
