A check on the quality of tap water in Ho Chi Minh City by the Ministry of Health showed that the content of chlorine, widely used to purify water as a disinfectant and bleaching agent, fails to meet required standards.

Chlorine concentration was found exceeding the maximum level in areas near the reservoirs of Saigon Water Supply Corporation (SAWACO) and being below the minimum rate in other areas far from the lakes, according to the results of the check.
