*Delete as appropriate
2 / NATURE OF CONTRAVENTION AND ITS CAUSE
The metaldehyde[m2] and total pesticides parameters exceed or are at risk of exceeding the prescribed concentrations in the zones listed in the Annex to this Schedule because of concentrations of metaldehyde in the raw water.
3 / MAXIMUM DEVIATION OF QUALITY
The prescribed concentration for metaldehyde (individual pesticide) is 0.1µg/l and for total pesticides is 0.5 µg/l and remain so irrespective of this undertaking. However, the prescribed concentration(s) are at risk of being exceeded while the remedial steps set out in this Schedule are being undertaken.
