Regulation 2(1) and (4)
1 The parametric values in Part 2 are not required to protect human health (since the parametric values in Part 1 are sufficient for that purpose). The values in Part 2 are not therefore set for the purposes of Article 5(3) of the Directive. | ||||
2 Compliance required as to 95% of samples from each service reservoir (regulation 4(4)). | ||||

Notes— |
1 The parametric value refers to the residual monomer concentration in the water as calculated according to specifications of the maximum release from the corresponding polymer in contact with the water. This is controlled by product specification. | ||||
2 See also regulation 6(6). | ||||
3 See also regulation 4(2)(c). | ||||
4 The corresponding parametric value applies to each ‘other pesticide’ individually. | ||||
5 The parametric values in this Part are not required to protect human health (since the parametric values in Part 1 are sufficient for that purpose). The values in Part 2 are not therefore set for the purposes of Article 5(3) of the Directive. | ||||

Notes— |
1 The water should not be aggressive. | ||||
2 In the event that the use of samples from a point within a water supply zone has not been authorised for this parameter under regulation 8, the point of monitoring is instead the consumer's tap. | ||||
3 This value, in so far as the point of monitoring is a service reservoir, is not set for the purposes of Article 5(3) of the Directive. | ||||
4 This value, in so far as the point of monitoring is a treatment works, is not set for the purposes of Article 5(3) of the Directive. | ||||
[F15 Remedial action is to be deemed justified on radiological protection grounds, without further consideration, where radon concentrations exceed 1,000 Bq/l.] | ||||
[F16 If the concentration of tritium exceeds this value, an analysis of the presence of other artificial radionuclides must be also carried out by Scottish Water.] | ||||

Policy Note sets out a brief statement of the purpose of a Scottish Statutory Instrument and provides information about its policy objective and policy implications. They aim to make the Scottish Statutory Instrument accessible to readers who are not legally qualified and accompany any Scottish Statutory Instrument or Draft Scottish Statutory Instrument laid before the Scottish Parliament from July 2012 onwards. Prior to this date these type of notes existed as ‘Executive Notes’ and accompanied Scottish Statutory Instruments from July 2005 until July 2012.

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. The first date in the timeline will usually be the earliest date when the provision came into force. In some cases the first date is 01/02/1991 (or for Northern Ireland legislation 01/01/2006). This date is our basedate. No versions before this date are available. For further information see the Editorial Practice Guide and Glossary under Help.
