S.L. 449.57 Art. 9Remedial action and restrictions in use.

(1) The competent authority shall ensure that any failure to meet the parametric values set in accordance with regulation 6 is immediately investigated in order to identify the cause.

(2) If, despite the measures taken to meet the obligations imposed in regulation 5(1), water intended for human consumption does not meet the parametric values set in accordance with regulation 6, and subject to regulation 7(2), the competent authority shall ensure that the necessary remedial action is taken by the water supplier as soon as possible to restore its quality and shall give priority to their enforcement action, having regard inter alia to the extent to which the relevant parametric value has been exceeded and to the potential danger to human health.

(3) Whether or not any failure to meet the parametric values has occurred, where any supply of water intended for human consumption constitutes a potential danger to human health, the competent authority shall inform the Licensing Authority which shall prohibit the distribution, or restrict the use, of such water by the water supplier concerned as the case may be, or shall ensure that any other action which may be necessary to protect human health is taken by the water supplier. In addition the water supplier, following consultation with the competent authority, shall promptly inform consumers and give the necessary advice.

(4) The competent authority shall decide what action under the preceding sub-regulation should be taken, bearing in mind the risks to human health which would be caused by an interruption of the supply or a restriction in the use of water intended for human consumption.

(5) The competent authority may establish guidelines to assist the water suppliers to fulfill their obligations under sub-regulation (3).

(6) In the event of non-compliance with the parametric values or with the specifications set out in Schedule I, Part C, the competent authority shall consider whether that non-compliance poses any risk to human health. It shall ensure that water suppliers take remedial action to restore the quality of the water where that is necessary to protect human health.

(7) The competent authority shall ensure that, where remedial action is taken, water suppliers shall immediately notify consumers except in those cases where the competent authority considers the non-compliance with the parametric value to be trivial.
