The Drinking Water Quality Regulator has published its annual summary of drinking water quality in 2012.
Looking at private water supplies across Scotland, the main facts included in the report are:
- 3% of Scotland’s population relies on PWS for their drinking water.
- In 2012 there were 19,916 registered PWS in Scotland which were reported to the DWQR, 2,434 Type A and 17,482 Type B.
- A total of 57,358 tests were carried out on samples taken from PWS, with 91% of tests complying with the standards; 39,006 from Type A supplies (93% compliance) and 18,352 from Type B supplies (83% compliance).
- Of 31 local authorities in Scotland with PWS in their areas, only two achieved full compliance with their check sampling duties.
- The quality of all PWS, particularly microbiological quality, continues to be of concern. Almost a quarter of Type B supplies failed the E.coli standard.
- The number of supplies failing the lead standard is expected to almost double when the standard is tightened later in 2013.
- In the 2012-13 financial year £1.58 million of grants were awarded for PWS improvements.
