Call it the big flush. Because a 21-year-old man was caught on a security camera urinating into a city reservoir, Oregon's biggest city is sending 8 million gallons of treated drinking water down the drain. Portland officials defended the decision Monday, saying they didn't want to send city residents water laced, however infinitesimally, with urine. Public health officials say, however, that urine is sterile in healthy people and that the urine in the reservoir was so diluted — perhaps a half pint in millions of gallons — that it posed little risk. Some people in the city, in the suburbs and around the world called the flush an overreaction, especially since animals such as ducks contribute waste routinely and, sometimes, die in the water/Associated Press.

Question: Did Portland over-react to human pee in the reservoir?
