Cambridge Domestic Water Quality

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 Cambridge 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.英国水务公司承担饮用水质量检测的法定职责。本数据集收录了剑桥水务（Cambridge Water）从民用住宅水龙头采集的样本检测结果，以验证水质符合英国及欧盟立法所制定的标准。该数据涵盖了由饮用水监察局（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。诸多英国水务公司会在其官方网站提供水质搜索工具，用户可通过邮政编码检索所在区域的饮用水水质情况，检索结果将匹配至对应邮政编码所属的供水区域。供水区域与低层超级输出区（Lower Layer Super Output Areas, LSOAs）并无关联，因此此类检索结果或与本数据集存在差异。部分样本的检测结果会受室内管道系统影响，无法代表更大范围区域的饮用水整体水质状况。另有部分样本在采样现场完成检测，其余样本则被移送至科研实验室开展分析测试。
