Be it airborne chlorine or chlormines, it is an air-quality challenge. Facilities need to take pool ventilation seriously, especially ways to draw fresh air across the water surface where chloramines tend to linger (they are heavy). However, getting facilities to upgrade their ventilation is hard: it is a substantial cost and there are very little health and occupational safety regulations. Standard pool inspections do not check air quality; and air-quality inspections are time consuming (4h+) and expensive (>1K). At a societal level, we need to be putting patron and staff pressure on facilities that have ventilation problems and letting others now about these health issues.
