Hafren Dyfrdwy Domestic Tap 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 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.英国水务公司肩负饮用水水质检测的法定职责。本数据集收录了哈夫伦·迪夫德威（Hafren Dyfrdwy）从居民家庭水龙头采集的水样检测结果，用于验证其符合英国及欧盟法规所规定的水质标准。该数据涵盖了英国饮用水监察局（Drinking Water Inspectorate, DWI）明确要求的测定参数的采样地点、采样日期及实测浓度值。当前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自身所在区域的饮用水水质信息，查询结果将匹配至对应的供水区域。需注意的是，供水区域与LSOAs并无对应关联，因此该数据集的结果或与上述邮政编码查询结果存在差异。部分水样的检测结果会受到室内管道系统的影响，无法代表更大范围内区域的饮用水水质整体状况。另有部分水样采用现场检测方式，其余样本则被送往科研实验室完成检测分析。
