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.英国水务公司负责饮用水水质检测工作。本数据集收录剑桥水务（Cambridge Water）从居民家庭取水口采集的样本检测结果，用于验证其水质符合英国及欧盟立法设定的标准。该数据包含样本采集地点、日期以及饮用水监察局（Drinking Water Inspectorate, DWI）规定的检测指标实测浓度。英国多家水务公司在其官方网站提供水质查询工具，用户可通过邮政编码检索所在区域的水质信息，查询结果可匹配对应邮政编码所属的供水区域。供水区域与LSOAs无关联，因此查询结果可能与本数据集存在差异。部分样本的检测结果受户内管道系统影响，无法代表更大范围区域的饮用水水质。部分样本采用现场检测方式，其余样本则被送至科研实验室开展分析。
