The Philadelphia Tribune – Kelly O’Day is a retired wastewater engineer who tracks illegal dumping in Philadelphia in his spare time. There is no shortage of abandoned mattresses, old tires and plastic junk for the self-styled trash detective to sleuth. But Wednesday, the Mount Airy man took a break from the dirty streets to celebrate a win. After years of struggling to enforce city laws against illegal dumping, Philadelphia has taken 14 cases of illegal dumping to trial in the last five months. The cases, enabled by 50 new hidden street cameras, represent a milestone for the Kenney administration’s crackdown on illegal dumping.
