Hafren Dyfrdwy Domestic Tap Water Quality 2023

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 Hafren Dyfrdwy 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水质检测职责。本数据集收录了Hafren Dyfrdwy水务公司从居民家庭水龙头采集的水样检测结果，用于验证饮用水是否符合英国及欧盟立法规定的水质标准。该数据集涵盖了饮用水监察局（Drinking Water Inspectorate, DWI）规定的各项检测指标的采样位置、采样日期及实测浓度数据。英国多家水务公司均在其官方网站上线了邮编查询工具，用户可通过邮编检索所在区域的水质信息，查询结果将匹配至对应邮编所属的供水区域。供水区域与下层小输出区（Lower Layer Super Output Areas, LSOAs）并无关联，因此官网查询结果可能与本数据集存在出入。部分采样结果受家庭内部供水管道影响，未必能代表更大范围区域的饮用水水质状况。部分水样在现场完成检测，其余样本则送往科研实验室开展分析。
