New VLA neutral hydrogen maps for the amorphous starburst galaxy NGC 5253 are presented, along with HST optical and UV spectroscopy of the central HII regions. The data appear to show an infalling HI stream on the SE side of the galaxy which may be responsible for triggering the young burst of star formation. The central HII region exhibits a 300% nitrogen overabundance compared to the surrounding gas, and we propose that recent chemical pollution from massive stars is responsible.
