The quality of drinking water in 2011 remained exceptionally high, according to the Drinking Water Inspectorate (DWI). Around two million samples were taken in England and Wales, with 99.96% meeting or exceeding the strict standards set.
The DWI findings show that the investment that water companies are making in the quality and safety of drinking water is well-placed.
The lack of complacency in the water industry was also recognised, with the DWI acknowledging that remedial action that has been taken or is planned to rectify the 0.04% of samples where standards were not met.
In addition, the latest reports show that there is greater consistency of quality performance across the UK, with the North West and Wales in particular reporting increases in compliance.
