**Phoenix Pools: Desert Air Lies Inflaming Child Asthma?**
By Franklin Everett ShawThe scent of chlorine hangs heavy in the air, a familiar aroma for many Phoenix families enjoying their backyard pools. But could this seemingly harmless summertime staple be contributing to a less welcome trend: the rising rates of childhood asthma in our desert city? It’s a question worth asking, and more importantly, one that demands actionable solutions.
The link between pool chemicals and respiratory issues isn’t new. Chlorine, while effective at sanitizing, reacts with organic matter (sweat, sunscreen, even urine) to form chloramines. These chloramines, not the chlorine itself, are the primary culprits behind that “chlorine smell” and are also potent irritants to the respiratory system.
In Phoenix, the intense heat exacerbates this issue. Higher temperatures accelerate the formation of chloramines and increase their evaporation into the air, leading to higher concentrations around the pool area. This is especially concerning for children, whose lungs are still developing and are more susceptible to irritation.
So, what can Phoenix parents do to protect their children? It’s not about abandoning the pool altogether, but about adopting smarter pool management practices and being mindful of the unique challenges posed by our desert environment.
First, ventilation is key. Indoor pools are particularly problematic, but even outdoor pools benefit from good airflow. If your pool area is enclosed by walls or fences, consider adding openings or using fans to promote air circulation. This helps dissipate chloramines and reduces their concentration in the breathing zone.
Second, master the art of pool chemistry. Regular testing and balancing of your pool water are crucial. Invest in a reliable test kit (liquid test kits are generally more accurate than test strips) and learn how to interpret the results. Aim to maintain chlorine levels within the recommended range (typically 1-3 ppm) and keep the pH balanced (7.2-7.8).
Here’s a step-by-step guide to shocking your pool effectively, a process vital for breaking down chloramines:
- Test the water: Before shocking, test the pH and alkalinity levels. Adjust them to the recommended ranges first, as shocking is less effective if these are out of balance.
- Calculate the amount of shock: Use a pool shock calculator (available online) or follow the instructions on the product label to determine the correct amount of shock based on your pool’s volume. Under-shocking is a common mistake, leading to incomplete chloramine breakdown.
- Add the shock at dusk or night: Sunlight degrades chlorine, so shocking at night maximizes its effectiveness.
- Dilute the shock (if necessary): Some types of shock need to be pre-dissolved in a bucket of water before adding them to the pool. Always follow the product instructions carefully.
- Pour the shock around the perimeter: Distribute the shock evenly around the pool to ensure thorough mixing.
- Run the pump: Keep the pool pump running for at least 8 hours after shocking to circulate the water and facilitate the breakdown of chloramines.
- Test the water again: Before allowing anyone to swim, test the chlorine levels. They should be below 3 ppm.
Third, consider alternative sanitization methods. While chlorine is the most common option, there are alternatives that produce fewer chloramines. Saltwater systems, for example, generate chlorine through electrolysis, but at a lower concentration and with fewer byproducts. UV sanitizers and ozone generators can also be used in conjunction with chlorine to reduce the amount of chlorine needed.
However, be aware of the pitfalls. Saltwater systems require careful monitoring of salt levels and can be corrosive to certain pool equipment. UV and ozone systems are effective, but they don’t provide residual sanitization, meaning they only kill bacteria and algae that pass through the system.
Fourth, shower before swimming. This simple act can significantly reduce the amount of organic matter entering the pool, thereby minimizing chloramine formation. Encourage everyone to rinse off before taking a dip.
Fifth, be mindful of indoor pool environments. If you frequent indoor pools, pay attention to the ventilation. If the air feels heavy or you notice a strong chlorine odor, limit your time in the pool area. Consider wearing a mask to filter out chloramines.
Sixth, consult with a pool professional. A qualified pool technician can assess your pool’s specific needs and recommend the best sanitization and maintenance strategies for your situation. They can also help you troubleshoot any water chemistry issues.
Seventh, stay informed about Arizona Department of Health Services guidelines. The ADHS provides valuable resources on pool safety and water quality. Familiarize yourself with their recommendations and follow their guidelines for maintaining a healthy pool environment. You can find information on their website regarding recreational water safety.
Eighth, recognize the signs of respiratory irritation. If your child experiences coughing, wheezing, or shortness of breath after swimming, it could be a sign of chloramine exposure. Consult with your pediatrician to rule out other potential causes and discuss strategies for managing their symptoms.
Ninth, consider the location of your pool. In areas of Phoenix with poor air quality, the combination of pollution and pool chemicals could exacerbate respiratory issues. If you live near a busy road or industrial area, consider taking extra precautions to minimize exposure to both pollutants and chloramines.
Tenth, don’t rely solely on chlorine. A common mistake is to simply add more chlorine when problems arise. This often exacerbates the issue by creating more chloramines. Instead, focus on addressing the underlying cause of the problem, such as poor filtration, inadequate circulation, or high levels of organic matter.
Finally, remember that this is a complex issue with no easy answers. The link between pool chemicals and childhood asthma is still being studied, and more research is needed to fully understand the risks. However, by taking proactive steps to minimize chloramine exposure, Phoenix parents can help protect their children’s respiratory health and enjoy their pools safely. It’s about being informed, being proactive, and adapting to the unique challenges of our desert climate.
