The following link is to a presentation I prepared for a recent Public Relations class. The topic is the January 2014 chemical spill in West Virginia's Elk River. You can step through the presentation by clicking on the arrows at the bottom of the Prezi screen.
Three YouTube videos are incorporated into this presentation. It will take 10-20 minutes to view.
