Chlorates in Drinking Water: an Overlooked Risk
- Státní zdravotní ústav, Praha
Chlorate is not included in the group of parameters for routine monitoring of drinking water quality. That is why it is neglected by both water producers and the authorities. However, this disinfection by-product may under certain conditions occur in drinking water in high concentrations exceeding the probable limit value as has been shown in a survey of hundreds of samples of drinking water in one Czech region. High concentrations were found primarily in small water supplies and the most probable source of contamination is sodium hypochlorite used for disinfection, which is either old or stored under unsuitable conditions.
