Investigation on a Chemical Contamination Incident of Drinking Water

Objectives To reduce and avoid the incidence of drinking water contamination and to discuss and put forward suggestions and countermeasures. Methods An on-site investigation on the contaminated drinking water was carried out in a residential area, and water samples were collected for laboratory detection. Results The contents of styrene and hexachlorobutadiene in the four water samples collected from the water tanks and peripheral water outlets in this district were out of the limits prescribed in standards for drinking water quality. Conclusions The contamination of drinking water in this district was caused by improper painting jobs. It is suggested that the training and education of relevant water supply units and personnel on hygienic supervision and management of drinking water should be strengthened in order to prevent the incidence of water contamination.
