Or just another intruder the chlorine will seek and destroy?
    Bloodborne pathogens are quickly killed by normal FC levels. The CDC says that commercial pools do not need to be closed down after a blood spill but some commercial pools do it as a matter of course.

    Vomitus in pool water is actually more common and more of a problem. It is treated the same as for a formed stool fecal accident.

    The real question is how long and how much chlorine does it take to remove it from your pool?
    Urine is sterile until it reaches the urethra where the epithelial cells lining the urethra are colonized by facultatively aerobic Gram negative rods and cocci.
    Urine is toxic and can be irritating to skin and eyes.

    This is from wikipedia article on urine.

    I have a sign that says my pool has a "Uretek Urine Detector." It is supposed to be humorous but I can tell people take it seriously because everyone gives a nervous laugh.

    It is sterile. If you have gram negative rods and cocci in your urethra, you have a urinary tract infection. There is no normal flora in the urinary tract and thus, it is sterile.

    I suspect they are used to it. We live accross the street from and community center and city park, but the bathrooms in the community center and at the ball field are each 80-100 yards from the playground which seems to be too far for some of the nannies.

    [quote="link147"]I told my 6 year old nephew that we put this chemical in the pool. Later he came up to me and said, "The water never turned red!"

    It is not easy to detect when a kid pees in the pool. Unless, of course, they do it while they are standing on the diving board.

    Re: Is there a chemical to detect urine in the pool?

    My wife just knows when someone has, or is in the process of, peeing in the pool. Sixth sense, highly developed intuition or maybe the self-satisfied expression on the culprits face? I can't be sure.

    Re: Is there a chemical to detect urine in the pool?

    1 cup of urine contains 2891 mg N of nitrogenous compounds (mostly urea) so in a 10,000 gallon pool would use up at least 0.6 ppm FC though not right away (but probably within a few days if the pool is exposed to sunlight; urea is slow to get oxidized by chlorine). I have personal experience of this effect in Unusual Chlorine Demand -- Peeing in the Pool.
