| Pesticides— | Only those pesticides which are likely to be present in a given water must be monitored. | ||
| (a) individual substances— | |||
| (i) in the case of aldrin, dieldrin, heptachlor and heptachlor epoxide | 0.030 | µg/l | The parametric concentration applies to each individual pesticide. |
| (ii) in the case of other individual pesticides | 0.10 | µg/l | The parametric concentration applies to each individual pesticide. |
| (b) total pesticides | 0.50 | µg/l | The concentration for “total pesticides” refers to the total sum of the concentrations of all the individual pesticides detected and quantified in the monitoring procedure. |
| Polycyclic aromatic hydrocarbons | 0.10 | µg/l | The parametric concentration applies to the total sum of the concentrations of all the individual polycyclic aromatic hydrocarbons detected and quantified in the monitoring procedure. |
