Interdisciplinary concepts have been used to manage the environmental crisis of the 21st century. Ecological problems and solutions require an increasingly comprehensive soil study and this has been carried out in order to consider the entire regolith profile. Regoliths are the entire column of materials above the fresh rock, whether this is saprolite (literally “rotten rock”) or soil, material with intense biological and chemical process. Groundwater contamination is particularly enhanced in shallow, porous regolith profiles, due to the easiness of surface water flow into the groundwaters. This is particularly critical in the Guarani aquifer, which waters supplies 15 million people in 4 countries. Several morphological, chemical, physical and mineralogical analyses were applied to samples collected in three regolith profiles to infer, based on weathering and pedogenesis characteristics, their susceptibility to allow groundwater contamination. A particular challenge was that most of the weathering indices were proposed for igneous rocks, and the studied profiles had sedimentary rocks as parent materials. The most weathered profile (P2) had the least potential for groundwater contamination due to its higher cation exchange capacity (CEC) and clay activity, differentiated structure and consistency in the Bi horizon that can favor the lateral flow and the greatest thickness. Profile P1 had sandy texture, small CEC and thickness that facilitate the passage of soluble contaminants towards the groundwater. Some anox features in the Cr layer suggest the existence of a physical limitation that may delay infiltration or diverge water flow to surface outlets. The profile P3 had the greatest potential for groundwater contamination because it had low CEC, weathering degree and thickness. The only feature to prevent the polluted infiltration water to reach groundwaters in this profile was its sub-horizontal structure and transition from soft/very friable consistency in CA layer to very hard/unbreakable consistency in Cr layer, which also may diverge or delay the vertical infiltration of water. However, no anox features were found in it. Results indicate the importance of understanding the soil weathering and relate with their potential on underground water contamination, and thus, to bring light to public environmental monitoring policies.

跨学科概念已用于管理21世纪的环境危机。生态问题和解决方案需要对土壤进行越来越全面的研究，并且已经进行了这项研究，以便考虑整个re石特征。go石是新鲜岩石上方的整个材料柱，无论是腐泥土（字面“腐烂的岩石”）还是土壤，都是具有强烈生物和化学过程的材料。由于地表水易于流入地下水，因此在浅层多孔重水石剖面中特别增加了地下水污染。在瓜拉尼含水层中，这一点尤为关键，该水为4个国家的1500万人供水。将几种形态学，化学，物理和矿物学分析应用于从三种re石剖面中收集的样品，以推断，基于风化作用和成岩作用的特征，它们的敏感性使地下水受到污染。一个特殊的挑战是，大多数风化指数都被提出用于火成岩，并且所研究的剖面以沉积岩为母体。最风化的剖面（P2）由于其较高的阳离子交换容量（CEC）和粘土活性，Bi层中差异化的结构和稠度（可能有利于侧向流动和最大厚度）而被地下水污染的可能性最小。剖面P1具有沙质质地，较小的CEC和厚度，可促进可溶性污染物向地下水的通过。Cr层中的一些缺氧特征表明存在物理限制，可能会延迟渗透或使水流扩散到地面出口。轮廓P3具有较低的CEC，风化度和厚度，因此具有最大的地下水污染潜力。防止受污染的入渗水进入此剖面的唯一特征是其亚水平结构，并从CA层的软/非常脆性转变为Cr层中的非常坚硬/坚不可摧的转变，这也可能使垂直方向发散或延迟水的渗透。但是，在其中未发现任何缺氧特性。结果表明了解土壤风化的重要性，并将其与潜在的地下水污染联系起来，从而为公共环境监测政策提供启示。防止受污染的入渗水进入此剖面的唯一特征是其亚水平结构，并从CA层的软/非常脆性转变为Cr层中的非常坚硬/坚韧性，这也可能会分散或延迟垂直水的渗透。但是，在其中未发现任何缺氧特性。结果表明了解土壤风化的重要性，并将其与潜在的地下水污染联系起来，从而为公共环境监测政策提供启示。防止受污染的入渗水进入此剖面的唯一特征是其亚水平结构，并从CA层的软/非常脆性转变为Cr层中的非常坚硬/坚不可摧的转变，这也可能使垂直方向发散或延迟水的渗透。但是，在其中未发现任何缺氧特性。结果表明了解土壤风化的重要性，并将其与潜在的地下水污染联系起来，从而为公共环境监测政策提供启示。
