Can CO2 sensors in the ventilation system of a pool facility help reduce the variability in the trihalomethane concentration observed in indoor air?

Environment International, 2020
Volatile and hazardous compounds are formed during the chlorination of pool water. Monitoring components in the air, such as the four trihalomethanes; chloroform, dichlorobromomethane, dibromochloromethane and bromoform (tTHM), is challenging.

Combined UV LED and Chlorine for Synergistic Drinking Water Disinfection and Assessment of Disinfection By‐Product Formation

AWWA Water Science, Volume 7, Issue 6, November/December 2025.
ABSTRACT This study provides a comprehensive evaluation of the effectiveness of 280 nm UV LEDs in enhancing chlorine disinfection in natural water sources. The results of this work indicate sequential treatments (UV‐chlorine and chlorine‐UV) further enhanced the disinfection efficiency of T1 in natural waters, especially at higher UV doses, such as 40 ...

Risks of Birth Defects Following In Utero Exposures to Unregulated Brominated Haloacetic Acids

Birth Defects Research, Volume 117, Issue 10, October 2025.
ABSTRACT Introduction Haloacetic acids (HAAs) are water disinfection byproducts (DBPs) regulated as a mixture of five species (HAA5) in the United States and Canada. To date, two brominated HAAs (BrHAAs) in HAA5 (monobromoacetic acid [MBAA], dibromoacetic acid [DBAA]) have been associated with birth defects in some epidemiologic studies, but the other ...
