Clorox into the washer with a load of the childs socks, sheets, and other once-white clothes and never stop to wonder how bleach actually "bleaches" the clothing. The same can
be said for the person throwing a capful or two of chlorinating crystals into the backyard hot tub in order to sanitize the water. Very few users of chlorine bleach
or chlorine in other formulations care how it works . . . only that it does. What Chlorine Is and Does Even the most simple encyclopedic reference to chlorine
will explain: "Chlorine, symbol Cl, greenish-yellow gaseous element. In group 17 (or VIIa) of the periodic table, chlorine is one of the halogens. The atomic number of chlorine is 17"
(Encarta). Those same references will also explain that: "Free chlorine does not occur in nature, but its compounds are common minerals, and it is the 20th most abundant element in
the earths crust" (Encarta). And yet none of that information explain what chlorine has to do with laundry, disinfectant, swimming pools, or even the ability to wash colors out of
an item. Added to most common household uses of chlorine and bleach are the health and infections concerns related to public safety when recreating at facilities open to a large
number of people. For example, Carpenter, Fayer, Trout, and Beach (1999) explain that: "Swimming is the second most popular recreational activity in the United States, with more than 350 million
persons participating each year" (pp. 584). Keeping the water safe from infectious contaminants has been a public health concern for, literally, the past century. Carpenter and the others make note
of the fact that: "Frequent fecal contamination of recreational water and the high level of C. parvum oocyst resistance to chlorine, the low oocyst dose required for infection,
