Forty-something Montreal pools have been temporarily closed due to poor water quality. Water testing discovered (among other things) traces of urine and fecal matter in the water. If you are shocked by this information, you need to get out more. HELLOOOO?? Generations of snot-nosed kids have been peein' in pools since pee was invented! And I wouldn't put it past some of you so-called adults, either. Warm spots aren't a natural phenomenon.
I've been to public pools in my life. I don't NEED to do a water test to know there is urine in the pool. My test is this: I scan the pool. If there is one kid standing motionless with a relaxed look on his face for longer than 20 seconds...there's pee in the pool.
