  "text": "(This note is not part of the Regulations)\nThese Regulations prescribe a system for classifying the quality of controlled waters which are coastal or brackish waters and which need protection or improvement in order to support shellfish life and growth.\nThe classification SFW reflects the mandatory values assigned by Directive 79/923/EEC (the quality required of shellfish waters) 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 (Shellfish) Directions 1997, transpose Directive 79/923/EEC in relation to England and Wales. Copies of the Surface Waters (Shellfish) 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.",
