I was thinking the same thing. It seemed like a bit of an overreaction.
Draining reservoir after urination incident shows tenuous grasp of science
Portland throws out 38 million gallons of water after someone peed in it.
Trouble is, you have people who believe in Homeopathy, which says the more you dilute something, the more powerful it becomes. Utter, utter, complete nonsense, but here it would indicate the entire lake would be super-powerful urine medicine.
+Damian Trasler Yeah, that was kind of my thought in the headline. "Ignore the dead birds bobbing on the surface, there's someone's pee in there, and just because you probably couldn't detect it with any instrument known to humanity, that just means it's stronger!"
To quote Terry Pratchett
“A newt in a well was considered to show it was clean. Nobody asked if the newt got out before going to the toilet.”
I’m pretty sure reservoir water is cleaned between storage and consumption.
Don't forget insects.
