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特征。实现优良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。在此框架下，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工作组（PK HGW）开展德国境内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），编制了德国境内含水层相关地下水背景浓度的综合综述成果。相关结果与方法文档可于联邦地球科学与自然资源研究所（BGR）官网获取：<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，乃至其完成后，部分州级地质调查机构均针对以地质成因背景值为核心的天然地下水状态开展了相关描述工作。依托国别尺度的处理工作，可通过细化水文地球化学单元对其展开更为深入的研究。针对莱茵兰-普法尔茨州内天然普遍超压地下水的特征，研究团队以HÜK200制图成果为基础开展了相关调查，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>。这份关于天然普遍超压地下水特征的在线地图，展示了莱茵兰-普法尔茨州已细分的水文化学单元的物质特异性浓度数据。针对每个水文化学单元，报告均给出了对应参数的中位值（50%分位数）。所给出的中位值可作为天然超压地下水水质评估的参照变量，能够替代非点位针对性的现场勘查工作。
