Anglian Water Domestic Water Quality 2024

Data Origin Samples were taken from customer taps. They were then analysed, and the results were uploaded to a sampling system. This dataset is an extract from this database. Context 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. Data Triage We are sharing individual results, anonymised by mapping samples to LSOA (lower super output area). Data Specifications Each dataset will cover a calendar year of samples. This dataset will be published annually. The Determinands included in the dataset are as per the list that is required to be reported to the Drinking Water Inspectorate.
