Application and introduction of substances and products5B
Where a relevant person, in the preparation or distribution of a private water supply for human consumption purposes, applies any substance or product to, or introduces any substance or product into, the water which is to be supplied for those purposes, the person must take all measures necessary to ensure that, in doing so, the water supplied does not, at its point of use, contain the substance or product, or any impurity associated with the substance or product, at a concentration or value which would make the water unwholesome.
