A Study on the Effect of Indoor Air Pollution on Secondary Water Supply

Objectives To evaluate the effect of indoor air pollution on secondary water quality in a secondary water supply pollution event, and to provide scientific support for the control and prevention of indoor air pollution on the quality of water in a secondary water supply.

Methods Based on a field investigation and laboratory examination to propose and adjust the hypothesis for the source of pollution.

Results The odor of water samples was consistent with that of indoor air samples. High concentrations of xylene and ethylbenzene were determined in the indoor air and water samples.

Conclusions If the secondary water supply system was located in a closed indoor environment, the indoor air pollution might have an adverse influence on the quality of water for secondary water supply. Scientific design and installation of secondary water supply system and keeping good indoor air quality were crucial to ensure the quality of water from secondary water supply.
