1 in 5 Americans admits peeing in the pool

As noted in this thread my wife is a proud member of that 1 in 5.

As described in section 4.3 in this document, urine is composed mostly of urea and then some ammonia and some other nitrogenous compounds. The 12,220 ppm-N in urine takes over 93,000 ppm FC in that same urine volume to get rid of it. So adding 1 cup of urine in 15,000 gallons would consume around 0.4 ppm FC from the entire pool volume.

It is rather innocuous except as noted in terms of possible bacteria, but they should get killed quickly after the chlorine reacts with the ammonia (urea is slower to react with chlorine). If you have many children all peeing in the pool, then one should have a much higher chlorine level to take care of this extra demand.

Well now we know what to do if the pool gets over chlorinated :gone:
