Trace elements in soils from Guadiamar River Basin (SW Spain), year 2014

This data set contains information on chemical properties of soils from the Guadiamar River Valley (SW Spain). This set corresponds to a series of environmental surveys conducted in the Guadiamar River Valley to monitor de fate of contaminating trace-elements in soils after a huge mine accident that released acid waters and trace-element contaminated sludge into the Guadiamar River basin. Data included in this package were gathered between February and March 2014, 16 years after the mining accident (occurred in April 1998) and subsequent remediation programme. It includes soil data (general properties and quasitotal and soluble trace element concentrations) from 20 sampling sites along the Guadiamar River basin, with three topographic locations along the river section sampled at each of the 20 sites.
