Onondaga Lake in Syracuse, N.Y., has often been called the most polluted lake in America. It was hammered by a one-two punch: raw and partially treated sewage from the city and its suburbs, and a century's worth of industrial dumping. But now the final stage in a $1 billion cleanup is about to begin.
Standing in his office amid stacks of reports, scientist Steve Effler glances at an old front-page headline of the Syracuse Herald-Journal: "Divers find goo in Onondaga Lake."
After five years of crisscrossing the country as a traveling medical technician, David Kwiatkowski landed at New Hampshire's Exeter Hospital in the spring of 2011. A full-time job in the hospital's cardiac unit soon followed.
It was at Exeter that federal prosecutors say the 33-year-old began to divert syringes of the drug Fentanyl. They say Kwiatkowski, who was arrested July 19, would inject himself with the painkiller, and then refill syringes with a saline solution. He is hepatitis C-positive, meaning those tainted needles might have spread the liver-damaging virus.
