Southern Water Domestic Drinking Water Quality 2024

Water companies in the UK are responsible for testing the quality of drinking water. This dataset contains the results of samples taken from the taps in domestic households by Southern Water to make sure they meet the standards set out by UK and European legislation. This data shows the location, date, and measured levels of determinands set out by the Drinking Water Inspectorate (DWI). 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.英国水务公司肩负饮用水水质检测的法定职责。本数据集收录了南部水务（Southern Water）从英国家庭水龙头采集的水样检测结果，用于核验水样是否符合英国及欧盟立法制定的水质标准。数据涵盖英国饮用水监察局（Drinking Water Inspectorate, DWI）规定的各项检测指标的采样地点、采样日期及实测浓度值。英国多家水务公司在其官方网站上线了水质查询工具，用户可通过邮政编码检索所在区域的水质信息，查询结果将匹配对应邮政编码覆盖范围的供水区域。供水区域与LSOAs并不对应，因此查询结果可能与本数据集存在差异。部分采样结果受家庭内部管道系统影响，无法代表更大范围区域的饮用水整体水质状况。部分样本在采样现场完成检测，其余样本则被送往专业科研实验室开展分析。
