Busting a Chlorine Swimming Pool Urban Myth

Friday, July 27th, 2012

The Water Quality and Health Council would like to thank John Tesh for tweeting the results of our swimmer hygiene survey and for giving us an opportunity to address a very common urban myth.

John Tesh Tweet

Last week, musician, composer and radio talk show host John Tesh tweeted the finding from a recent Water Quality & Health Council survey that one in five swimmers admit to “peeing in the pool”. Tesh warns, “If you smell chlorine, stay out”. I appreciate the fact that Tesh raised this subject and respectfully submit that his tweet needs a tiny tweak.

A healthy chlorinated pool can emit a light chemical odor, especially if it is an indoor pool and one with less than ideal ventilation. It is good advice, however, to stay out of the water when a strong chemical smell pervades the air around any type of pool, indoor or outdoor. On this point John Tesh is absolutely correct.

What actually causes the distinctive, irritating smell around swimming pools is not chlorine–that’s an urban myth–but volatile substances known as chloramines. Chloramines form in pool water when chlorine combines with contaminants brought into the pool by swimmers. Think urine, perspiration, body oils and cosmetics. The truth is that cleaner swimming, not less chlorine, can help reduce the chloramine irritants that cause “swimmer red eye” and itchy skin. The Centers for Disease Control and Prevention’s swimmer hygiene tips recommend swimmers shower with soap before entering the pool (almost 70% of the survey respondents said they don’t do this routinely) and stop peeing in the pool.

The next sentence of Tesh’s tweet requires no tweaking at all: The smell gets stronger if there’s urine in the water. It is true that the more urine there is to combine with chlorine, the higher the level of unwanted, smelly chloramines in the pool. Following that thread, if chlorine is combining chemically with contaminants like urine, then it is not available to destroy germs in the pool that can make swimmers sick with diarrhea, swimmer’s ear and various skin infections.

Eighty-seven percent of respondents to the survey agreed with the urban myth that it is chlorine in pool water that makes swimmers’ eyes red and irritated. Ironically, the irritants actually responsible, chloramines, may be produced when there is not enough chlorine in the pool. The bottom line: Pool operators need to keep pool chemicals in appropriate ranges. Swimmers need to clean up their act. The proof will be in the air around the pool.

Swimmers can order free pool test kits from the Water Quality & Health Council to see if their pool pH and free chlorine levels are in the proper range.

It’s time to dig out the swim suits, sunscreen and beach towels and head to the pool. Swimming lessons, swim team, frolicking in the pool with friends, lap swimming and leisurely poolside chats are hallmarks of summer for families all over the country. As this fun season begins, we have some safety tips to offer.

Make sure your children have adult supervision while they are in the water.

Children ages one to four have the highest drowning rates of all age groups, according to a May 17 report by the Centers for Disease Control and Prevention (CDC). For every child who drowns, another four received emergency care for injuries.

In addition to supervision, adults should learn Cardiopulmonary Resuscitation (CPR) and avoid drinking alcohol while supervising children.

Most drowning of young children occur in backyard pools. To help prevent accidental drowning in these settings, install a four-sided pool fence of at least four feet in height to completely separate the pool area of the backyard. Don’t leave toys in or around the pool. Also, formal swimming lessons can help keep children safe in the water. The CDC website has more information on drowning prevention.

Use sunscreen at the pool.

CDC recommends sunscreen with sun protective factor (SPF) 15 or higher, and both UVA and UVB protection. Reapply sunscreen every two hours, and after you swim or sweat. Finally, check the expiration date on your sunscreen and keep in mind that high temperatures can degrade sunscreen before its expiration date.

Use pool test strips to check for adequate pool chemistry.

A 2008 CDC pool inspection survey conducted in 13 states found about one in eight public pools were closed immediately after inspection due to serious code violations (reported in 2010). Disinfection violations were most common in kiddie and wading pools and water play areas. Improperly maintained pools put swimmers at risk for diarrhea, swimmer’s ear and skin infections. CDC encourages families to take matters into their own hands and pack easy-to-use pool test strips when they take off for the pool. The strips can be used to check that pH and chlorine levels are in the appropriate range. This summer the Water Quality & Health Council is offering free pool test strips online at If levels are unsatisfactory, CDC recommends notifying the pool manager; if readings remain unsatisfactory, consult your local health department.

Here’s to a safe and healthy summer swim season!

Pool Chlorine Hypothesis Remains Unproven

Friday, March 2nd, 2012

Swimming researcher Dr. Joel Stager says swimming is “the only activity we know of where you can say that if that’s all you do for exercise, you can be almost perfectly fit.”
Swimming researcher Dr. Joel Stager says swimming is “the only activity we know of where you can say that if that’s all you do for exercise, you can be almost perfectly fit.”

Can pool swimming promote the development of asthma in children or help alleviate its symptoms? This question has been debated among researchers ever since Belgian Professor Alfred Bernard published a 2006 study supporting the “pool chlorine hypothesis”. That hypothesis suggests that the increasing exposure of children to pool chlorine could be contributing to the rise of childhood asthma in the developed world. Other studies have found swimming improves asthma symptoms; Welsh et al., for example, reviewed the relevant scientific literature and found “positive effects of swim training on fitness as measured by improved aerobic efficiency, physical working performance, and recovery heart rates.”

Since the Bernard study appeared, there has been much discussion of the pool chlorine hypothesis in the popular and scientific press. No research has confirmed Bernard’s findings. An extensive review of the literature conducted by Goodman and Hays in 2008 found asthma to be more likely among elite swimmers than among similar high-level participants in other competitive sports. Interestingly, it is unclear whether asthma in high-performance swimmers developed as a result of swimming or whether many high-performance swimmers are asthmatics who took up the sport when encouraged by their doctors to swim for therapeutic exercise (a true chicken and egg question–which came first?). That question aside, researchers could find no consistent association between asthma development and swimming pool use during childhood.

The Belgian Minister of Public Health in 2009 requested detailed scientific advice on this matter from her advisory body, the Superior Health Council. The Council responded in February, 2011 with a report stating that although a relationship between swimming pool attendance and childhood asthma has not been confirmed, it cannot yet be excluded. The Council concluded that, for now, the available evidence does not support advising children against swimming in chlorinated pools. That’s important because there are significant benefits to swimming.

How is a child’s life improved by learning to swim?

  • According to the Centers for Disease Control and Prevention (CDC) participation in formal swimming lessons can reduce the risk of drowning by 88 percent among children aged one to four years old.
  • Swimming can yield a broad range of benefits throughout a person’s lifetime. According to a 2006 article, swimming provides even resistance and a full-body workout, improving cardiovascular health, muscle tone and overall flexibility.
  • As many children and adults would agree, swimming is fun!

Keeping Swimming Healthy

A well-maintained pool is critical to healthy swimming, according to CDC. Proper pool chemistry, including adequate chlorine and pH, helps destroy waterborne pathogens that can cause everything from swimmer’s ear to gastrointestinal illness. Swimmers must also play a role in keeping swimming healthy by showering before swimming and not peeing in the pool. When pool operators and swimmers do their part to maintain healthy pools, there are fewer irritating disinfection byproducts generated in pools.

As with a lot of issues in life, everyone needs to balance known and suspected risks with known and suspected benefits. Early in my career as a physician, I was interested to learn that even bed rest has known risks. If swimming is important to your family, it’s important to stay informed on the latest health research. For now, the conclusion of the Belgian Superior Health Council is positive for parents who want their children to reap the considerable benefits of pool swimming.

Aquatic rehab: Not just for the dogs

Jake in the Under Water TreadmillHow cute is that? Little Jake over there is undergoing aquatic rehabilitation in an underwater treadmill after paralyzing his rear limbs in an unfortunate accident. One veterinarian’s initial prognosis was that Jake would not be able to walk again. But after physical therapy and the underwater treadmill, Jake is back on his feet and happier than ever.

Canines are not the only species that can benefit from aquatic therapy. Whether it is used to help people recover from acute injuries or to maintain health in the face of chronic disease, hydrotherapy is regarded as having “broad rehabilitative potential” that is relatively underused (Becker, 2009).

Water: An ideal medium for exercise.

Swimming is widely recommended by medical experts for its healthful benefits*. According to the American Red Cross, the buoyancy of water results in less stress on the joints, helping to reduce swelling and tissue damage. Warm water can increase circulation, decrease pain, and increase muscle relaxation and soft tissue flexibility.

Patients (and puppies) looking to strengthen muscles should exercise in pools with some turbulence.
Aquatic exercise: Benefits galore

  • Lower risk of death In a 2009 Washington State University study of over 40,000 men, exercise swimmers had less than half the mortality risk of sedentary men, and exercise swimmers had half the mortality risk of exercise walkers and runners.
  • Aids patients with COPD A 2009 study of patients with chronic obstructive pulmonary disease (COPD) found the swimming pool a “feasible and positive alternative venue for pulmonary rehabilitation”.
  • Asthma Many studies have found swimming improves asthma symptoms; LaKind et al. cite Welsh et al. 1, who reviewed the relevant scientific literature. According to LaKind et al., Welsh et al. note that most studies find “positive effects of swim training on fitness as measured by improved aerobic efficiency, physical working performance, and recovery heart rates.”
  • Heart healthy Aquatic exercise strengthens the heart muscle and improves oxygen delivery to the muscles.
  • Reduces water and sodium retention Animal data collected in Brazil 2 indicate exercise in water might be prescriptive for patients with hypertension, obesity and/or mild renal disease as it reduces water and sodium retention.
  • Hand eye coordination and balance According to a study done in Taiwan, swimming can improve hand eye coordination and balance in the elderly, which could lower a senior’s risk of a falling-related injury.
  • Bone health Aquatic exercise can maintain or improve bone health in post-menopausal women.
  • Better flexibility and range of motion According to the American Red Cross, when accompanied by good stretching habits, aquatic exercise can greatly improve flexibility and aid range of motion.
  • Improved mood Swimming can improve the mental state of both men and women, the elderly and women with fibromyalgia, mothers, and parents of children with developmental disabilities.

Swimming may be the BEST and most enjoyable form of exercise, so give it a try!

*The American Red Cross recommends a health assessment from your health care provider before you begin an exercise program.

Swimming in the News

Monday, August 1st, 2011

by the Water Quality & Health Council

With high temperatures plaguing much of the country, the pool seems like the best bet to beat the heat. This blog highlights two interesting and entertaining resources recently found in the media that can help keep swimming healthy and enjoyable.

1. CDC’s Healthy Swimming 2011 Video Contest Winner’s Video!

This summer, the Centers for Disease Control and Prevention (CDC) challenged the public to create a short video to help educate swimmers about pool safety.  The winners, David and Aaron Mathews, worked with friends and family to develop “Recreational Water Illness Police,” a clip that uses humor to inform viewers about the most common recreational water illness—diarrhea. Roger that.

2. Quiz:  Is It Safe To Pee In The Pool … And Other Water Safety Questions

Want to test your water safety knowledge? A Huffington Post online quiz emphasizes key swimming safety issues, some of which are often overlooked, such as showering before entering the pool.  It is important that swimmers shower with soap (especially swimmer “bottoms”) before swimming so they do not introduce harmful bacteria into the pool.  This fact is lost on all but 25 percent of parents according to a recent report.  And no, it is not safe to pee in the pool.


Understanding Swimming Pool Chemistry

Monday, July 25th, 2011

By Fred Reiff, P.E.

It’s no secret that swimming pools, although fun and refreshing, are essentially communal bath tubs. To help keep water clean and safe, pool operators must adjust pool chemical levels. Maintaining proper pool chemistry can be a challenging task, especially in community pools where the number of swimmers fluctuates wildly from hour to hour.  Add to that the fact that many swimmers are unaware of the role of personal hygiene in keeping waters safe, and one begins to understand the magnitude of the pool operator’s responsibilities.

Chlorine and pH Get it Done

Chlorine is strongly associated with swimming in popular culture.  Although there are persistent myths about chlorine in swimming pools, chlorine is used as a disinfectant in the majority of pools to help prevent waterborne illnesses such as diarrhea, swimmer’s ear and skin infections.  Alternative sanitizers have been introduced in the marketplace over the last several years, but chlorine continues to offer the most effective and economical option to helping maintain safe pools.

Chlorine actually serves two purposes: it destroys algae and most waterborne germs, and it reacts with—oxidizes—small bits of organic debris and impurities introduced into pool water by swimmers.  Chlorine does this work in the form known as free chlorine, a combination of hypochlorous acid and hypochlorite ion.  Free chlorine is produced in pool water when chlorine disinfectant is added.  When free chlorine reacts with nitrogen-bearing or organic substances, the product is known as combined chlorine, a much weaker disinfectant and oxidant. The World Health Organization recommends free chlorine levels up to 3 mg/l be maintained in swimming pools.

As pool operators know, hypochlorous acid1 is a more effective disinfectant and oxidant than the hypochlorite ion 2, and their relative proportions fluctuate with the pH (acidity) of the water in the pool (low pH is more acidic and high pH is more basic).   To maintain optimal levels of hypochlorous acid for germ and algae destruction while at the same time keeping the water comfortable for swimmers, pool operators should maintain pH in the slightly basic range of 7.2 to 7.8.

Monitoring, Monitoring, Monitoring

One of the most important tasks of the swimming pool operator is vigilantly monitoring the pH and free chlorine level of pool water to ensure germs are being destroyed.  This is critical because chlorine may be depleted, for example, by a heavy “bather load”.  A crowded swimming pool adds more organic debris (e.g., perspiration, body oils, trace urine and fecal matter), which can lower the chlorine level or even deplete it, leaving little or no protection against waterborne germs.

A 2010 report from the Centers for Disease Control and Prevention (CDC) found one in eight public pool inspections conducted in 13 states in 2008 resulted in pools being closed immediately due to serious code violations, including insufficient disinfectant.  That is why CDC encourages swimmers to take matters into their own hands and (1) shower and thoroughly wash their bottoms before entering the pool and (2) use portable pool test strips to monitor for adequate free chlorine and pH.  As a public service, the Water Quality and Health Council is making these strips available free to the public this summer at  Swimmers will have to wash their own bottoms.

Teach Your Children Well: Shower before Swimming

Friday, July 1st, 2011

By Joan Rose, Ph.D.

You are heading off to your community pool. The mental check list goes…

Sunscreen?  Yes.

Bathing suit?  Of course.

Shower?  Probably not.

Although the “shower before you swim” rule is consistently posted at community pools, a new University of Michigan report shows parents of young children do not appreciate the role showering plays in keeping swimming pools safe for the community (see video).  Whereas 64 percent of parents understand it is very important for children to avoid swallowing pool water, only 26 percent believe it very important to shower before swimming.  This study highlights the need to educate parents on swimmer hygiene.

The researchers polled 865 parents of elementary school children, aged 5 to 12 years old.  More than twice as many parents surveyed believe drowning at a water park is a significant risk compared to those who perceive a high potential risk of getting sick from the water in these settings.

Showering before swimming or visiting a water park is a must because it helps remove trace levels of fecal matter and associated pathogens on human skin.  Put bluntly, the most critical area of the body to wash is your bottom. Not surprisingly, young children and babies in diapers are very likely to contribute fecal matter to pools.  An ongoing shigellosis outbreak in northern Kentucky pools has caused the local health department to prohibit children who are not yet potty-trained from accessing pools (see blog).  Shigellosis causes diarrhea and is transmitted through inadvertent contact with fecal matter of infected individuals.

According to the Centers for Disease Control and Prevention (CDC), recreational water illnesses (RWIs) are on the rise. RWIs are caused by germs spread by swallowing, breathing in mists or aerosols or having contact with contaminated water in swimming pools, hot tubs, water parks, water play areas, interactive fountains, lakes, rivers, or oceans. More than 10,000 Americans are sickened annually by RWIs, which can cause diarrhea, vomiting, abdominal cramps and fever or skin, ear, respiratory and eye infections.

Sixty-five percent of parents polled agree that preventing RWIs is a shared responsibility between parents and pool staff; 28 percent believe that preventing infections is the sole responsibility of the water park staff. Chlorine and proper pool chemistry kill most of the germs that cause recreational water illnesses within an hour, and are essential to good pool management, but Cryptosporidium, a parasite that causes abdominal cramping, diarrhea and nausea, can survive for days even in properly disinfected pool.

The solution to preventing RWIs is a collaborative effort between park and pool operators and swimmers. The following simple preventive measures require the cooperation of informed parents:

  • Shower or wash all parts of your body thoroughly with soap and water before swimming, paying special attention to the diaper areas of young children.
  • Take children on bathroom breaks and check infant diapers often.
  • Remind children to avoid swallowing water or getting water in their mouths.
  • Do not swim if ill with diarrhea.

Healthy pools are a shared responsibility.  Parents, teach your children well:  Shower before swimming!

Shigella Outbreak: New Hampshire, Take a Good Look at Kentucky

Tuesday, June 21st, 2011

Children who are not potty trained are no longer allowed in public pools in four Kentucky counties.  In addition, swimmers who have had diarrhea must not venture into pools for two weeks after diarrhea has subsided.  The Northern Kentucky Health Department set new restrictions for all public pools in response to a recent Shigella outbreak (see news video).  The outbreak demonstrates the importance of reducing the risk of fecal contamination of swimming pool water by using all available resources, including pool inspections, to address swimmer hygiene and appropriate disinfection.

The health department’s response to the outbreak has been appropriately aggressive, including arming environmental inspectors with waterborne disease prevention messages.  In contrast, a similar outbreak in a state such as New Hampshire, which is currently entertaining the notion of eliminating pool inspections to save state dollars, could be much worse.

According to the Centers for Disease Control and Prevention (CDC) website, Shigella is a group of bacteria that can cause diarrhea (often bloody), fever and stomach cramps within a day or two of exposure.  The bacterial infection that results from exposure to this organism, shigellosis, is spread via contact with the stool of an infected person through contaminated hands, food and water.  It is especially common in toddler childcare environments.

Swimming pools in Kentucky likely became contaminated when swimmers with shigellosis shed fecal matter into the water, which uninfected swimmers inadvertently ingested.  In a June 2 press release, District Director of Health, Lynne M. Saddler, MD, MPH, said, “…the bacteria spread easily through water— infection can occur between the time a person with Shigella has an accident in a pool and the bacteria is killed by the chemicals in the pool water. Shigella can be spread after the symptoms end, so people who have had diarrhea recently should not swim, even if they feel better and the diarrhea has ended….Even if children are in plastic diaper pants or diapers designed for use in water, commonly called swimmies, you can’t guarantee that fecal matter will not escape into the pool water.”  Since April of this year, the number of shigellosis cases in Boone, Campbell, Grant and Kenton Counties in Kentucky are more than triple the annual average.

The operators of 350 pools have been given information and educational materials, including instructions to pool operators on the proper response (e.g., “hyperchlorinating” the swimming pool) to fecal accidents.  Tips from the CDC and the health department include a warning to swimmers to: avoid swallowing pool or water playground water; shower before swimming; wash hands after using the toilet and changing diapers; take children on frequent bathroom breaks; and change diapers in bathrooms, not poolside.

CDC’s website notes the past two decades have brought a substantial increase in the number of recreational water illness outbreaks associated with swimming.  New Hampshire, take a good look at Kentucky for evidence that de-funding pool inspections is simply penny wise and pound foolish for public health.

Three Swimming Pool Lies I Grew Up With

Monday, June 6th, 2011

A Guest Blog by Mom and Swimmer Kristen Swope

I grew up believing some pool-related myths that I realize rather belatedly were my parents’ bizarre, yet caring way to keep me from drowning or getting injured during unsupervised swims.  A few childhood pool story-swapping moments with friends revealed other gems that were also considered truths at the time. I’ve decided to compile the top three ones I believe are worth correcting even if some of them seem downright funny.

1. If you urinate in a swimming pool, the chlorine will turn the water around you blue.

My childhood friends and I actually fell for this one hook, line and sinker!  What can I say?  It was an effective tool to make us use the toilet instead of just hoping our bladders wouldn’t betray us as we relieved our childhood selves in the pool. So finally, the truth:  No “special” chlorine makes the water blue (or green, if we were to go by primary color combinations) when urine mixes with pool water.  It would be great if someone came up with a formula to make this possible.  How quickly we would correct this unhygienic practice!

2. Chlorine in pool water causes rashes and eye irritation.

Research and personal experience as an adult would tell me that properly chlorinated pool water will do no such thing, and that kiddie rash, red eyes, and other forms of skin and eye irritation are usually due to irritants formed when disinfectants combine with pool water contaminants, such as urine, perspiration and body oils. This can be remedied by making sure the pool water pH is in the right range (7.2-7.8), and appropriate chlorine levels (1 – 4 parts per million).

3. You should not swim right after eating.

If you grew up in a family like mine, chances are you know how frustrating it was during those times when the pool seemed to be calling out your name and you just want to jump in, but couldn’t…because you’d just eaten a sandwich. Unfortunately, this old wives’ tale stayed with me right until adolescence, when I hemmed and hawed at a swimming party because I had eaten two slices of pizza and was terrified that cramps would cause me to drown in the pool. My friends laughed at my apprehension and plunged right into the pool water, their bellies full of pizza.

Several interviews with competitive swimmers revealed that they, in fact, eat normal-sized meals (definitely not just one sandwich or a couple of slices of pizza) before going about their fitness routines in the pool. While more complex swimming styles such as the butterfly stroke admittedly are harder to execute on a full stomach, none of the athletic swimmers I talked to ever experienced cramping because they ate something prior to casual swimming.

I am now the mom of an inquisitive and swimming pool-crazy little girl named Isabel.  I realize that telling her tall tales about the pool is silly, and that it’s best to communicate tried-and-tested and fact-based rules to ensure her safety whenever she’s in or near a swimming pool.
