 Notes:     Pesticides” means:     organic insecticides,      organic herbicides,      organic fungicides,      organic nematocides,      organic acaricides,      organic algicides,      organic rodenticides,      organic slimicides, and     related products (inter alia, growth regulators) and their relevant metabolites, degradation and reaction products.    Only those pesticides which are likely to be present in a given water need to be monitored.      The maximum concentration applies to each individual pesticide. In the case of aldrin, dieldrin, heptaclor and heptachlor epoxide the maximum concentration is 0.030 μg/l.      The maximum concentration for “total substances” refers to the sum of the concentrations of all individual pesticides detected and quantified in the monitoring procedure.      The specified compounds are benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(ghi)perylene, indeno(1.2,3 cd) pyrene.     ,

 Notes:     The total viable colony count should be measured within 12 hours of bottling, with the sample water being kept at a constant temperature during that 12 hour period. Any increase in the total viable colony count of the water between 12 hours after bottling and the time of sale should not be greater than that normally expected.      In 72 hours on agar-agar or an agar-gelatine mixture.      In 24 hours on agar-agar.     ,

 Notes:     The maximum concentration specified applies to the sum of the concentrations of the specified parameters.      The parametric value refers to the residual monomer concentration in the water as calculated according to specifications of the maximum release from the corresponding polymer in contact with the water.     ,

 Notes:     The method of analysis used to measure the concentration of the constituents in Schedule 6 shall be able to measure at least concentrations equal to the parametric value with the specified accuracy, precision and detection limits.      Regardless of the sensitivity of the method of analysis, the result must be expressed to the same number of decimal places as the maximum limit set out in Schedule 6 for the particular constituent being analysed.      Accuracy is the systematic error and represents the difference between the average value of a large number of repeated measurements and the exact value.      Precision represents the random error and is expressed in general as the standard deviation (within a batch and between batches) of a sample of results from the average.      Acceptable precision is equal to twice the relative standard deviation.      The detection limit is–     three times the relative standard deviation within a batch of a natural sample containing a low concentration of the constituent; or      five times the relative standard deviation within a batch of a virgin sample.         The method should make it possible to determine total cyanide in all its forms.     ,
