A pool technician arrives at your property to perform routine service—weekly pool cleaning for residences, and service three to five times a week for commercial properties. You see the pool cleaner take various measurements and then add some liquids and powder chemicals to the pool water. You might be wondering, “What is that stuff?” “Are those chemicals safe?” “How long should I wait to swim after the pool cleaner leaves?”
These are questions that our Certified Pool Operators (CPO) get often when they’re in the field servicing pools and spas. Ultimately, people want to know: Is my pool water safe? And, more specifically, some families are concerned about the health of babies, young children, pets or individuals with skin conditions that could be aggravated by chemicals.
We think these are important questions to ask your pool professional. As a wise consumer, it’s good to know exactly what is in your pool water—you need the truth.
The good news: When a trained, experienced CPO is cleaning your pool on a routine basis (as determined by the pool’s use and typical bather load), the water is safe for swimming. Pool water is healthy, well-balanced, clean and comfortable.
Let’s get more specific now and answer the question concerning what chemicals we add to pool water, what they do, and what other pool water safety concerns you should know about.
