| Aldrin | 0.030 | μg/l | |
| Dieldrin | 0.030 | μg/l | |
| Heptachlor | 0.030 | μg/l | |
| Heptachlor epoxide | 0.030 | μg/l | |
| Other pesticide | 0.10 | μg/l | Note 7 |
| Pesticides: total | 0.50 | μg/l | Notes 6 and 8 |
| Polycyclic aromatic hydrocarbons | 0.10 | μg/l | Note 9 |
| Selenium | 10 | μg/l | |
| Tetrachloroethene and trichloroethene | 10 | μg/l | Note 10 |

| Note 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. |
| Note 2: Where possible, without compromising disinfection, an enforcing authority (in relation a supply of water) must strive for a lower value. |
| Note 3: The parametric value applies to a sample of water obtained by an adequate sampling method at the tap and taken so as to be representative of a weekly average value ingested by consumers of the water. Where appropriate the sampling and monitoring methods must be applied in accordance with any guidelines under Article 7(4) of Council Directive 98/83/EC on the quality of water intended for human consumption(1). Each enforcing authority in relation to the water must take account of the occurrence of peak levels that may cause adverse effects on human health. |
| Note 4: When implementing measures to achieve compliance with this parametric value, each enforcing authority (in relation supplies of water to premises) must progressively give priority where lead concentrations in the water are highest. |
| Note 5: The additional parametric value of 0.10 mg/l applies only if the water is subject to treatment to improve its quality. The point of compliance for this additional parametric value is the point at which the water flows out from the treatment works. |
| Note 6: “Pesticide” means an organic insecticide, organic herbicide, organic fungicide, organic nematocide, organic acaricide, organic algicide, organic rodenticide, organic slimicide, a related product (including growth regulator) and any relevant metabolite, degradation or reaction product. Only those pesticides which are likely to be present in a supply of water need to be monitored. |
| Note 7: “Other pesticide” means a pesticide other than aldrin, dieldrin, heptachlor and heptachlor epoxide. The parametric value applies to each “other pesticide” individually. |
| Note 8: The parametric value for this parameter is the sum of all individual pesticides detected and quantified in the monitoring procedure. |
| Note 9: The parametric value for this parameter is the sum of the concentrations of benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(ghi)perylene and indeno(1,2,3-cd)pyrene. |
| Note 10: The parametric value for this parameter is the sum of the concentrations of tetrachloroethene and trichloroethene. |
| Note 11: The parametric value for this parameter is the sum of chloroform, bromoform, dibromochloromethane and bromodichloromethane. |

Policy Note
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.
