13. Where water supplied by a distribution system comes in whole or in part from non-disinfected groundwater having a vulnerability index for the bacteriological protection area that is greater than 100 using the DRASTIC method, the person in charge of the distribution system must collect or have a sample collected of the raw water taken or stored that supplies the distribution system at least once a month to test for the presence of Escherichia coli bacteria and enterococci bacteria if works or activities likely to alter the microbiological quality of the water are present within the bacteriological protection area of the catchment site established on the basis of a 200-day groundwater migration time.

Where water supplied by a distribution system comes in whole or in part from non-disinfected groundwater having a vulnerability index for the virological protection area that is greater than 100 using the DRASTIC method, the person in charge of the distribution system must also collect or have a sample collected of the raw water taken or stored that supplies the distribution system at least once a month to test for the presence of F-specific coliphage viruses if works or human activities such as a sewer system, the spreading of septic tank sludge or a domestic waste water infiltration field likely to alter the microbiological quality of the water are present or are carried on within the virological protection area of the catchment site established on the basis of a 550-day groundwater migration time.
