26.—(1) If a district council determines that water bottled and labelled as “spring water” or bottled drinking water does not comply with the parametric concentrations or values specified in Schedule 7, the district council 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 district council 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” or bottled drinking water constitutes a potential danger to human health, irrespective of whether it meets the relevant parametric values in Schedule 7, the district council 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) In performing the function in paragraph (2), the district council must have regard to any 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.
