Some samples are collected to ensure compliance with regulations established by UK and European legislation, while others are gathered for operational monitoring. This dataset includes a combination of both regulatory and operational data. All of the samples were collected from household taps by Dwr Cymru Welsh Water. The dataset provides information on the location, date, and measured levels of various determinands. Many UK water companies provide a search tool on their websites where you can search for water quality in your area by postcode. The results of the search may identify the water supply zone that supplies the postcode searched. Water supply zones are not linked to LSOAs which means the results may differ to this dataset Some sample results are influenced by internal plumbing and may not be representative of drinking water quality in the wider area. Some samples are tested on site and others are sent to scientific laboratories.
