The most common sanitizer found in pools. Like Bromine, it is a member of the halogen family. It dissolves in water to give hypochlorous acid which sanitizes the water. Chlorine is provided by various chlorine donors each with advantages and disadvantages. These are:- Chlorine products can beneficially be added at night to your water, when there is no ultraviolet light to degrade them. This way the chlorine has chance to work on the contaminants in your pool overnight. See also Bleaching Out See also Breakpoint Chlorination
A term used to describe any type of chlorine compound used as a disinfectant in swimming pool and spa water or to kill, destroy or control bacteria and algae. In addition, chlorine oxidizes ammonia and nitrogen compounds (swimmer and bather waste).
In its "normal" state, chlorine is a greenish yellow gas, but at -34°C it turns to a liquid. It is the eleventh most common element in the earth's crust and is widespread in nature. Chlorine is a key building block of modern chemistry and used in three principal ways: direct use (e.g. to disinfect water); as a raw material for chlorine-containing products (e.g. plastics, pharmaceuticals, pesticides) and as an intermediate to manufacture non-chlorinated products (eg polycarbonates and polyurethanes).
The mainstay of disinfection in the U.S. water system, chlorine was once completely effective against ordinary bacteria but not potent against the protozoan cryptosporidium, which form cysts that are impervious to this chemical. Other organisms, including mycobacteria and cyclospora, are evolving to develop immunity to chlorine, just as many infections in the human body no longer respond to antibiotics. Water systems with high bacterial counts, such as the one that serves Washington, D.C., are often treated with increased levels of chlorine, which further exposes residents of the city to THMs.
A small amount of chlorine is used in some places to kill living things (pathogens) in the water supply that would make people sick if they drank them. However, it disappears (degrades) with time and the pathogens can regrow if the water is not covered.

Chlorine in one of a number of forms is added to water to destroy or deactivate disease-causing microorganisms and is the mostly widely used disinfectant in the United States. Elevated chlorine levels can great aesthetic problems (strong taste and odor) and if organic matter is present it can result in the creation of trihalomethanes, which are potentially carcinogenic with target organs including the liver and kidney. Chlorine will evaporate from water by letting it sit in a bucket, open, for 24 hours.

Chlorine, an inorganic chemical that can be obtained both naturally and synthetically, has a huge variety of uses, as a disinfectant and purifier, in plastics and polymers, solvents, agrochemicals and pharmaceuticals, as well as an intermediate in manufacturing other organic and inorganic substances. Chlorine is also used worldwide to purify water supplies as the ultimate defence against waterborne microbiological infection.
Chlorine gas (elemental chlorine) is produced through the electrolysis of salt water, a process first designed to turn salt water into table salt. Originally an unwanted by-product of the salt making process, the sheer volume of chlorine gas created meant that uses for it must be found. These include pulp bleaching, plastics and pesticide manufacture, domestic and industrial bleach, and chemical warfare.
To ensure good quality drinking water, chlorine is added to kill bacteria that may cause disease. We test for the residual chlorine that needs to be present to make sure that the water is disinfected all the way to your tap. The health guideline value for chlorine depends on the type used. Some systems use 'free' chlorine (5 mg/L) and others use monochloramines (3 mg/L)

Chlorine is the most widely used drinking water disinfectant in North America. Adding a small amount of chlorine to drinking water protects the water from bacteria and other microorganisms. Chlorine is added to drinking water as either a gas or after having been already dissolved in water. Chlorine is measured in the field using portable analytical instrumentation. In order to meet Federal and State microbiological drinking water regulations, it is Tucson Water policy to ensure that there is a detectable amount of chlorine in 95 percent of the samples taken from the water distribution system. To optimize microbiological protection and minimize taste and odor problems, Tucson Water works to maintain a chlorine level between 0.6 parts per million and 1.0 parts per million throughout the distribution system. When the level of chlorine is above 0.5 parts per million, many people can smell chlorine in the water.

Chlorine is a disinfectant which wipes out bacteria and is added to most all municipal water systems. Chlorine may produce undesirable taste and odor in drinking water, such as a "swimming pool" taste. The actual health danger comes from some of the chemical compounds chlorine forms by combining with organic molecules that can be found in water. Activated carbon is the best solution to reducing chlorine in water.
Used widely by water utilities for water disinfection. It may produce undesirable taste and odor in drinking water.
(Water & Water Treatments) Chlorine is used by the water providers to prevent bacterial growth in the water between production and consumption. While it is extremely efficient, its presence can cause a poor taste in some beverages.
A chemical gas that is commonly added to tap water to insure bacteriological safety.
Cl2, molecular chlorine, in the stratosphere, atomic (radical) chlorine is very destructive because it depletes the greatly needed ozone layer which protects the earth from ultraviolet radiation from the sun. In the Antarctic stratosphere, molecular chlorine along with nitric acid are formed by the reaction of hydrogen chloride and chlorine nitrate--both stratospheric chlorine reservoir species. This process occurs on polar stratospheric clouds which serve as the reaction sites. Once formed, Cl2 vaporizes into the surrounding air as nitric acid--also formed in that process--binds with the ice matrix. Cl2 is then photodissociated in sunlight (lamda = 450 nm) into chlorine radicals. These chlorine radicals then catalytic destroy ozone. [Graedel, T. E. and Crutzen, Paul J. Atmospheric Change, An Earth System Perspective. pgs 145-6. W. H. Freeman and Company, 1993.
