Text us a pool question!

In this episode of the Talking Pools Podcast, Andrea and Paulette dive into the often-misunderstood world of chloramines—the compounds that cause everything from pool odor to swimmer irritation. They explore the science behind monochloramine, dichloramine, and trichloramine, explaining how each one forms, how they differ, and why they matter. The conversation goes deeper into the differences between organic and inorganic chloramines, uncovering how bather waste, nitrogen compounds, and pool chemistry all play a role in their development.

Listeners will walk away with a clearer understanding of what’s really happening in the water, why “that pool smell” isn’t chlorine at all, and practical insights into preventing and managing chloramine formation in pools.

Key Takeaways:

• Chloramines are responsible for eye irritation, respiratory discomfort, and that notorious “pool smell.”
• Monochloramine is the first stage of chlorine bonding with nitrogen.
• Dichloramine and trichloramine form as chlorination continues, each with stronger odor and irritation potential.
• Organic chloramines are formed from reactions with organic matter (like sweat, urine, and skin cells), while inorganic chloramines form with nitrogenous waste (like ammonia).
• Proper breakpoint chlorination and good water management can prevent chloramine buildup.
• Ventilation in indoor pools plays a critical role in reducing trichloramine exposure.
• Chloramines don’t just affect swimmer comfort—they also corrode pool equipment over time.

Memorable Sound Bites:

• “That smell you think is chlorine? Nope—it’s chloramines.”
• “Chlorine isn’t the villain here. Poor management is.”
• “Organic or inorganic, chloramines are a wake-up call for pool pros.”
