Any water which has had chlorine added to it. Swimming pools don't go out and buy chlorinated water from someone who has a lake full of the stuff, or anything like that. They use tap water, and add some chlorine. +++ Mains supply water is filtered then chlorinated at the treatment works, but to only about 2ppm. Swimming-pools work at 2 - 4ppm so more chlorine-donor is added to the pool.
Freshwater is not salty. Saltwater is salty.
To find out which type of water contains the least amount of chlorine, you would need a chlorine test kit, various types of water samples (tap water, bottled water, filtered water, etc.), and a measuring cup or container. Follow the instructions on the test kit to test the chlorine levels in each water sample and compare the results to determine which type has the least amount of chlorine.

There are two type of water filtration systems, apart from those uses in home. Small scale and large scale water purification. After water becomes free of visible impurities, we add chlorine to it. It is extremely economical and kills almost all microorganisms (Except ova and cysts, witch are already removed by good water purification. ) with in an hour or so. There are theoretical disadvantages of chlorinated water, like it causes cancer, witch is not true when used in recommended concentration. Best advantage of chlorine is that is is active for any length of time (say one year.) and will kill the microorganism if re contamination occurs. There are no supporters of chlorine, as it is very economical and no body is interesting in marketing it. For chlorine to act water must be free from organic substances.
Pool chlorine is typically stronger and designed to treat larger bodies of water, such as swimming pools. Spa chlorine is milder and formulated for smaller bodies of water, like hot tubs or spas.
