There are outstanding changes not yet made by the legislation.gov.uk editorial team to The Water Supply (Water Quality) (Scotland) Regulations 2001. Any changes that have already been made by the team appear in the content and are referenced with annotations.
Changes and effects yet to be applied by the editorial team are only applicable when viewing the latest version or prospective version of legislation. They are therefore not accessible when viewing legislation as at a specific point in time.

Item | Parameters | Concentration or Value (maximum) | Units of Measurement | Point of compliance |
---|---|---|---|---|
1. | Coliform bacteria | 0 | number/100ml | service reservoirs {s001} and water treatment works |
2. | Escherichia coli (E coli) | 0 | number/100ml | service reservoirs and water treatment works |
Notes: {s002} 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. {s003} See also regulation 6(6). {s004} See also regulation 4(2)(d). {s005} See the definition of “pesticides and related products" in regulation 2. {s006} The parametric value applies to each individual pesticide. {s007} Pesticides: Total means the sum of the concentrations of the individual pesticides detected and quantified in the monitoring procedure. {s008} PAH means Polycyclic Aromatic Hydrocarbons, the specified compounds are: benzo(b)fluoranthene benzo(k)fluoranthene benzo(ghi)perylene indeno(1,2,3-cd)pyrene. The parametric value applies to the sum of the concentrations of the individual compounds detected and quantified in the monitoring process. {s009} The parametric value applies to the sum of the concentrations of the individual compounds detected and quantified in the monitoring process. {s010} “THM: Total" means total Trihalomethanes, the specified compounds are: – chloroform – bromoform – dibromochloromethane – bromodichloromethane. The parametric value applies to the sum of the concentrations of the individual compounds detected and quantified in the monitoring process. | ||||

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.
