Disposition versions
19. The person in charge of a distribution system that supplies more than 5,000 persons must, for the control of pesticides and other organic substances referred to in Schedule 2, collect or have at least 1 sample of the water supplied collected annually during each of the quarters beginning on 1 January, 1 April, 1 July and 1 October, with a minimum interval of 2 months between samplings.
Where the analyses of the water samples collected pursuant to the first paragraph show that the concentration of every substance referred to in Schedule 2 is lower than 80% of the maximum concentration prescribed for each substance by Schedule 1, the person in charge of the distribution system must collect or have collected samples only once every 3 years, as long as the concentration of each substance is maintained at that level. As soon as one of the substances referred to in Schedule 2 shows a concentration that is not lower than 80% of the maximum concentration provided for in that Schedule, the samples must be taken in accordance with the provisions of the first paragraph.
This section does not apply to a distribution system supplied by another distribution system that is subject to the testing requirements for the substances listed in Schedule 2.
