    Everyone knows you jump in the pool in summer, smell the chlorine, and know the water is clean, right?

    Fun fact- chlorine dissolved in pool water at the usual sanitation levels has almost no perceptible smell or taste.
    HOWEVER, when chlorine binds with certain organic substances, especially ammonia (from the urea in sweat and urine), the result is chloramine which has a significant chlorine-y smell. Chloramine has essentially no disinfecting properties.

    So when you go to the public pool and get a whiff of chlorine and think ‘man they’re using a lot of chlorine today’, no, it probably means someone peed in the pool.

    You’re welcome :)

      Ok, but why then when you open a bottle of bleach or container of chlorine pellets, does it smell like chlorine. Do they add the piss ahead of time?

        take all but 1.5mL out of that gallon jug of household bleach, then fill it back up with water. that’s roughly the concentration of chlorine in a swimming pool.
