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 overstamped groundwater quality and replace non-site-based on-site investigations.天然普遍叠加赋存的地下水特征。保障地下水水质达标是欧盟水框架指令（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年委托地下水背景值专项工作组（PK HGW）开展德国地下水背景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），系统梳理了德国各含水层相关的地下水背景水平全貌。相关研究成果与方法文档可于德国地球科学与自然资源研究所（Federal Institute for Geosciences and Natural Resources, BGR）官网查询：<a href="https://www.bgr.bund.de/DE/Topics/Water/Projects/Completed/Consultation/Background Values/hgw_projektbeschr.html?nnn=1548666" target="_blank"></a>。 部分全国性处理工作开展前期，部分州级地质调查机构已基于地质成因背景值，完成了德国天然地下水现状的描述工作，该成果亦成为全国性处理工作的产出之一。针对各州的专项处理则通过更细致的水文地球化学单元划分，实现了对相关单元的深入解析。针对莱茵兰-普法尔茨州内天然普遍叠加赋存的地下水特征，研究团队以HÜK200制图成果为基础开展了调查，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>。 该天然普遍叠加赋存地下水特征在线地图展示了莱茵兰-普法尔茨州内细分水文化学单元的物质特异性浓度特征。针对每个水文化学单元，数据集均给出了对应参数的中位数（50%分位数）。所提供的中位数可作为天然普遍叠加影响地下水水质评估的参照变量，替代非原位的现场调查工作。
