Portland throws out 38 million gallons of water after someone peed in it.
David Shaff, Portland's water bureau administrator, reserves a special disgust specifically for human urine. In 2011, when Shaff drained the reservoir following a urination, he reasoned to the Portland Mercury, "Do you want to be drinking someone's pee?… There's probably no regulation that says I have to be doing it but, again, who wants to be drinking pee?" This time around, Shaff wrote in a statement, "Our customers have an expectation that their water is not deliberately contaminated."
A half-liter of urine dumped in a 143 million-liter reservoir would get a urea concentration of about 3 parts per billion, according to Slate. (We calculated it would be a 50 nanoMolar solution.) Meanwhile, the EPA allows concentrations of arsenic in drinking water up to 10 ppb. Salt water has a salt concentration of around 35,000,000 parts per billion, or 600 milliMolar.
In an interview with Vocativ, the teenager in question, Dallas Swonger, denied urinating in the reservoir at all, stating he actually hit a wall instead. "I leaned up against the wall and pissed on it," Swonger said. Swonger also contested the cleanliness of the reservoir prior to his actions: "I’ve seen dead birds in there. During the summer time I’ve see hella dead animals in there," Swonger told Vocativ. In 2011, Shaff told the Mercury that the reservoir is not shut down for nature's transgressions. "If we did that, we'd be shutting it off all the time. We fish out animals or things that have blown in all the time," Shaff said.
