<abstract> <p>Municipal solid waste landfills leachate can cause serious environmental issues for groundwater quality. Therefore, the application of tracing methods to identify contamination by municipal is significant. Hydrogeochemical evaluations trace are usually carried out. The study was out at a landfill in central Italy (Umbria). Samples and have been analyzed evaluate impact...

This study aims to evaluate the hydrogeochemistry of aquifers in Fars province, Iran, from 2007 2017 and assess groundwater’s suitability for drinking agricultural uses. A total 35,000 samples were collected wells qanats across province. Piper, Gibbs, Durov diagrams used hydrochemical facies processes. Cross plots different ions investigated ion exchange determine effects anthropogenic activiti...

以安徽淮南采煤沉陷积水为研究对象，通过样品采集与测试，研究不同沉陷年限及类型积水水文地球化学和氢氧稳定同位素组成特征及影响因素.结果表明：（1）研究区水化学类型主要为Cl-Na、HCO3·Cl-Na型，沉陷积水中常量离子主要来源于蒸发岩溶解和硅酸盐风化，受蒸发作用和人为活动的影响明显，水化学组成随沉陷时间和类型变化不大.（2）淮南大气降水线方程为：δD=8.85δ18O+18.73，沉陷区积水氢氧稳定同位素值在淮南大气降水线右下方依次分布并接近降水线，表明沉陷积水主要来源于大气降水.（3）在降水稀释、水体蒸发及地下水补给的作用下，随着沉陷年限的增加，积水中重同位素越来越贫化，同一年限不同类型的积水同位素值变化较小.;Taking the coal mining subsidence water in Huainan, Anhui Provi...

Many studies were conducted to investigate arsenic mobilization in different alluvial plains worldwide. However, due to the unique endemic disease associated with arsenic (As) contamination in Taiwan, a recent research was re-initiated to understand the transport behavior of arsenic in a localized alluvial plain. A comprehensive approach towards arsenic mobility, binding, and chemical speciatio...
