this schedule. They shall always be monitored not less than at the frequencies set out in the Table in point 2. Group B: In order to determine compliance with all parametric values set out in these Regulations, all other parameters not analysed under Group A and set in accordance with Regulation 6, except for parameters set out in Table D in Schedule 1, shall be monitored not less than at the frequencies set out in Note 2 to the Table, unless a different sampling frequency is determined on the basis

the supply system as referred to in Regulation 11, the list
parameters considered in the monitoring shall be extended and the sampling frequencies set out in Part 2 increased where any

not less than three years, from sampling points representative
