Water pollution control (Freshwater quality standards to preserve the life of fish) Ordinance of 2001 (P.I. No. 10/2001).

This Ordinance applies to inland waters which need protection or improvement to enable the life and development of certain freshwater fish species (Salmo salar, Salmo trytta, Thymallus thymallus, Coregonus, Cyprinidae, Esox lucius, Perca fluviatilis and Anguilla anguilla). The water quality parameters are specified in the Table annexed to the text of the Ordinance. The waters will be considered suitable and will meet the quality objectives of the Ordinance if all water samples will be taken with the frequency specified in the Table at the same sampling areas and for the duration of a twelve months period. The standard identification methods regarding the parameters of water quality are set out in the Table. Other methods of identification may be used provided the results are as accurate as specified in the Table. This Ordinance does not apply where the quality standards are not met because of floods or natural disasters or exceptional weather conditions or where the water undergoes natural enrichment of fish species.
