Swimming pool chemicals are at the center of a fierce, high-stakes debate. Pool chemical manufacturers are dedicated to convincing us that we need a bewildering amount of chemicals. And it’s working. More than a billion dollars in pool chemicals are sold each year. But there‘s a problem.
For decades, pool owners have been told to maintain their pools with high concentrations of chlorine and nearly a dozen different chemicals. Now we know that human skin is much like a sponge, absorbing what it comes in contact with. A ground-breaking study presented by the American College of Sports Medicine found exposure to traditional chlorine levels constricted airways in the lungs leading to coughing, wheezing, and shortness of breath. Unfortunately these problems are just the tip of the iceberg. Get the full story on the unknown side effects at pool chlorine studies.Read More
It's probably no surprise that some pool chemicals are harmful. What you may not know is that the most dangerous pool chemicals were never added to your pool. That's right. You're probably asking yourself, “Why should I be concerned with chemicals I didn't add to my pool?”
The answer may surprise you. All pools contain organic matter such as leaves, debris, perspiration and even urine and feces. Researchers have discovered that certain pool chemicals such as chlorine react with organic matter in a way we never imagined. During complicated chemical reactions, chemicals may combine to form a completely new chemical compound. Researchers call these compounds disinfection by-products. Some are harmless but some are bad news for pool owners. A study published in the American Journal of Epidemiology found that swimming in chlorinated pools increased bladder cancer risk by 57%.Read More
Recent studies have positively linked disinfection by-products to allergies, asthma and even higher rates of cancer. Top scientists are telling us the impact to our children is five times greater than exposure to second-hand smoke. There is an abundance of credible evidence that indicates that pool chlorine levels should be lowered. Second, researchers have found that all types of chlorine react with organic matter to form hundreds of chlorine by-products. Some proponents of salt water pool systems argue that they produce less dangerous chemicals than traditional chemicals. However, some studies have indicated the opposite. The good news is that ultraviolet light disinfection is compatible with all types of chlorine, including chlorine manufactured in salt water pools.Read More
