Nature of natural, ubiquitously over-embossed groundwater. Achieving good quality groundwater status is one of the objectives of the EU Water Framework Directive (WFD). In this context, among other things, the State Geological Services of Germany (SGD) commissioned the group of persons background values groundwater (PK HGW) with the determination and statistical interpretation of the background values in groundwater in 2005. As a result, a comprehensive overview of aquifer-related background levels in groundwaters in Germany was compiled for hydrochemically similar units (HGCs). The results and method documentation are available on the website of the Federal Institute for Geosciences and Natural Resources (BGR) <a href='https://www.bgr.bund.de/DE/Topics/Water/Projects/Completed/Consultation/Background Values/hgw_projektbeschr.html?nnn=1548666' target='_blank'></a>. Preceding the nationwide processing partly, but also as a result, descriptions of the natural groundwater condition in the sense of geogenous background values were made by some geological state services. The country-specific processing made it possible to examine the hydrogeochemical units in more detail by means of a greater differentiation of the hydrogeochemical units. The nature of natural, ubiquitously over-embossed groundwater in Rhineland-Palatinate was investigated on a cartographic basis of the HÜK200 and the <a href='https://www.lgb-rlp.de/de/service/lgb-downloads/hydrogeologie-d.html#c2559' target='_blank'>results report</a> was published in 2012. The online map on the nature of natural, ubiquitously over-embossed groundwater shows the substance-specific concentrations for the hydrochemical units differentiated in Rhineland-Palatinate. For each hydrochemical unit, the median value (50% percentile) of the corresponding parameter is given. The given median values represent orientation variables in the assessment of the natural, ubiquitously over-embossed groundwater quality and replace non-site-based on-site investigations.天然普遍超压地下水的赋存特征。达成良好的地下水水质状态，是欧盟水框架指令（EU Water Framework Directive, WFD）的核心目标之一。在此背景下，德国国家地质调查局（State Geological Services of Germany, SGD）于2005年委托地下水本底值工作组（PK HGW），负责德国地下水本底值的测定与统计解析工作。 最终，研究团队针对水文化学相似单元（hydrochemically similar units, HGCs），系统梳理了德国含水层相关地下水本底浓度的综合概况。相关研究成果与方法文档可于德国联邦地球科学与自然资源研究所（Federal Institute for Geosciences and Natural Resources, BGR）官网查询，链接为：<a href='https://www.bgr.bund.de/DE/Topics/Water/Projects/Completed/Consultation/Background Values/hgw_projektbeschr.html?nnn=1548666' target='_blank'></a>。 在全国性处理工作的部分阶段推进期间及最终成果产出后，部分州级地质调查机构已针对地质成因本底值范畴内的天然地下水状态开展了描述工作。通过国别专属的处理流程，可借助水文地球化学单元的精细化划分，对相关单元开展更为深入的研究。 莱茵兰-普法尔茨州（Rhineland-Palatinate）的天然普遍超压地下水赋存特征，以HÜK200制图数据集为基础开展了调研，并于2012年发布了<a href='https://www.lgb-rlp.de/de/service/lgb-downloads/hydrogeologie-d.html#c2559' target='_blank'>成果报告</a>。 本次天然普遍超压地下水特征在线地图，展示了莱茵兰-普法尔茨州划分出的各水文化学单元的物质专属浓度信息。针对每个水文化学单元，均给出了对应参数的中位值（50百分位数）。该中位值可作为天然普遍超压地下水水质评估的参考变量，替代了无需针对特定场地的现场勘查工作。
