  "text": "(This note is not part of the Regulations)\nThese Regulations prescribe a system for classifying the quality of inland freshwaters which need protection or improvement in order to support fish life.\nThe classifications SW (“salmonid waters”) and CW (“cyprinid waters”) reflect the mandatory values assigned by Directive 78/659/EEC (on the quality of fresh waters needing protection or improvement in order to support fish life) to the parameters listed in the Schedule to these Regulations.\nThe Regulations also incorporate the reference methods of measurement, and the minimum frequency required for sampling and analysis, laid down in that Directive for those parameters.\nThe Regulations, together with the Surface Waters (Fishlife) Directions 1997, transpose Directive 78/659/EEC in relation to England and Wales. Copies of the Surface Waters (Fishlife) Directions 1997 may be obtained from:\nWater Quality Division\nDepartment of the Environment,\nRomney House,\n43 Marsham Street,\nLondon SW1P 3PY.\nEnvironment Division,\nWelsh Office,\nCathays Park,\nCardiff CF1 3NQ.",
