Results are out from new findings on how to calculate % of pee in swimming pools, here's a couple of excerpts from the article
The scientists calculated that one 220,000-gallon, commercial-size swimming pool contained almost 20 gallons of urine. In a residential pool (20-by-40-foot, five-feet deep), that would translate to about two gallons of pee. It's only about one-hundredth of a percent, but any urine in a swimming pool can be a health concern for some people, not to mention that smell that never quite goes away.
Researchers monitored two public pools for three weeks for ACE. One pool contained 110,000 gallons of water, while the other held 220,000 gallons.
Based on the ACE measurements, researchers estimate that over the 3-week period, swimmers released 7.92 gallons of pee into the smaller pool, and nearly 20 gallons into the larger one.
