Is Chlorine Really a Safe Pool and Spa Disinfectant?

poolWhile there are no conclusive studies showing a direct correlation between chlorination of swimming pools and specific health hazards, there are many studies which have demonstrated that long term exposure to chlorinated municipal drinking water significantly increases certain types of cancer in humans.

Certainly, if no altermative disinfection method for swimming pools and spas is available, then chlorination is preferable to no disinfection. However, with new advances in on site water disinfection, it is now not only possible, but can often be more cost effective to implement non chlorine disinfection systems for your swimming pool and/or hot tub needs.

In case you were wondering whether it was worth your time to investigate and make the switch from chlorine to an alternative disinfecting system, here are a few facts to consider:

“Known carcinogens are found in drinking water as a direct consequence of the practice of chlorination”

“48-49 states are failing to adequately enforce existing drinking water regulations.” JAMES ELDER – U.S. ENVIRONMENTAL PROTECTION AGENCY

“Scientists discovered that chlorine reacted with organic material in water to produce hundreds of chemical by-products, several of which have proved in animal studies to be carcinogenic.” U.S. NEWS AND WORLD REPORT – JULY 29, 1991
