Regulation 12 Sampling and analysis
When the Department monitors a private supply it must take a sample—
from a tap normally used to provide water for human consumption and which, if there is more than one tap, is representative of the water supplied to the land;
if the water is supplied for food production purposes, at the point at which it is used for those purposes; or
if the water is supplied from a tanker, at the point at which it emerges from the tanker.
The Department must ensure that any sample taken is analysed.
The Department may enter into an arrangement for any person—
to take and/or analyse samples on its behalf; and
to report its findings to the Department as soon as they are available and to report any breach of these Regulations to it immediately.
The Department may provide for any such person to be reimbursed.
The Department must not enter into an arrangement under paragraph (3) unless it is satisfied that the task will be carried out promptly by a person who is competent to perform it.
Samples taken in accordance with this regulation must be taken at regular intervals so as to be representative of the quality of the water consumed throughout the year.
The further provisions for sampling and analysis in Schedule 4 apply.
