26.—(1) If a food authority determines that water bottled and labelled as “spring water”, “dŵr ffynnon”, or its equivalent in any other language, or bottled drinking water, does not comply with the parametric concentrations or values specified in Schedule 7, the food authority must—
(a)immediately investigate the non-compliance in order to identify the cause;
(b)assess whether the non-compliance poses a risk to human health which requires action;
(c)require the business operator to take remedial action as soon as possible to restore the quality of the water where that is necessary to protect human health;
(d)in respect of any parameter specified in Parts 2 and 3 of Schedule 7, notify the general public of the remedial action taken, unless the food authority considers that non-compliance with the parametric value is trivial; and
(e)in respect of any parameter specified in Part 4 of Schedule 7, notify the general public of the risks and remedial action taken and advise the general public on any additional precautionary measures that may be needed for the protection of human health in respect of radioactive substances.
(2) If water bottled and labelled as “spring water”, “dŵr ffynnon”, or its equivalent in any other language, or bottled drinking water, constitutes a potential danger to human health, irrespective of whether it meets the relevant parametric values in Schedule 7, the food authority must—
(a)prohibit or restrict the supply of that water in its area or take such other action as is necessary to protect human health; and
(b)inform the general public promptly of that fact and provide advice where necessary.
(3) A food authority is not required to prohibit or restrict the supply of water under paragraph (2)(a) if it considers that such action will give rise to an unacceptable risk to human health.
