Without prejudice to the provisions of article R. 1321-47, when the quality limits are not complied with and whether or not this non-compliance is attributable to the private distribution system, the person responsible for producing or distributing the water must take the necessary corrective measures as quickly as possible in order to restore the quality of the water.
The person responsible must inform the mayor and the director general of the regional health agency, who will forward this information to the prefect responsible for the area, of the effective application of the measures taken. It gives priority to the application of these measures, taking into account, among other things, the extent to which the quality limit has been exceeded and the potential danger to human health.
For packaged water, the provisions applicable are those of article R. 1322-44-7.
