Amendment of Schedule 1S
8. In Schedule 1 (prescribed concentrations and values) to the 2006 Regulations—
(a)in Part II (national requirements) of Table B (chemical parameters), omit the entries for—
(i)item 3 (hydrogen ion);
(ii)item 6 (odour); and
(iii)item 9 (taste);
(b)in Table C (indicator parameters)—
(i)in the heading for column (3), after “maximum” insert “ unless otherwise stated ”;
(ii)after the entry for item 5 (colony count) insert—
| “5A. | Colour | Acceptable to consumers and no abnormal change”; |
(iii)after the entry for item 6 (conductivity) insert—
| “6A. | Hydrogen ion | 9.5 6.5 (minimum) | pH value |
| 6B. | Odour | Acceptable to consumers and no abnormal change | |
| 6C. | Radon (for radioactivity)(ii) | 100 | Bq/l”; |
(iv)after the entry for item 7 (sulphate) insert—
| “7A. | Taste | Acceptable to consumers and no abnormal change”; |
(v)after the entry for item 10 (tritium) insert—
| “10A. | Turbidity | Acceptable to consumers and no abnormal change”; |
(vi)in the entry for item 8 (total indicative dose), omit “(ii)” and “/year”; and
(vii)in the entry for item 10 (tritium), after “(for radioactivity)” insert “ (iii) ”; and
(c)in the notes to Table C, for note (ii) substitute—
“(ii)Remedial action is to be deemed justified on radiological protection grounds, without further consideration, where radon concentrations exceed 1,000 Bq/l.
(iii)If the concentration of tritium exceeds this value, an analysis of the presence of other artificial radionuclides must be also carried out by Scottish Water.”.
