There are outstanding changes not yet made by the legislation.gov.uk editorial team to The Natural Mineral Water, Spring Water and Bottled Drinking Water Regulations (Northern Ireland) 2007. Any changes that have already been made by the team appear in the content and are referenced with annotations.
Revised legislation carried on this site may not be fully up to date. Changes and effects are recorded by our editorial team in lists which can be found in the ‘Changes to Legislation’ area. Where those effects have yet to be applied to the text of the legislation by the editorial team they are also listed alongside the legislation in the affected provisions.

Whole provisions yet to be inserted into this Rule (including any effects on those provisions):
Regulations 2(1), 10(1)(b), 13, 19 and 21(2)
1. Water satisfies the requirements of this Schedule if —N.I.
(a)the water does not contain —
(i)any micro-organism (other than a parameter) or parasite, or
(ii)any property, element or substance (other than a parameter),
at a concentration or value which would constitute a potential danger to human health;
(b)the water does not contain any substance (whether or not a parameter) at a concentration or value which, in conjunction with any other property, element, substance or organism it contains (whether or not a parameter), would constitute a potential danger to human health;
(c)the water does not contain concentrations or values of any of the parameters listed in Tables A to D in Part 2 in excess of the prescribed concentrations or values; and
(d)in the case of water prepared from water which has been softened or desalinated, its hardness is not below a minimum concentration of 60 mg Ca/l.

Notes: 1. “Pesticides” means:
related products (inter alia, growth regulators) and their relevant metabolites, degradation and reaction products. Only those pesticides which are likely to be present in a given water need to be monitored. 2. The maximum concentration applies to each individual pesticide. In the case of aldrin, dieldrin, heptaclor and heptachlor epoxide the maximum concentration is 0.030 µg/l. 3. The maximum concentration for “total substances” refers to the sum of the concentrations of all individual pesticides detected and quantified in the monitoring procedure. 4. The specified compounds are benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(ghi)perylene, indeno(1.2,3-cd) pyrene. | |||

This timeline shows the different points in time where a change occurred. The dates will coincide with the earliest date on which the change (e.g an insertion, a repeal or a substitution) that was applied came into force.
