abstract background: leachate produced by waste disposal sites can be contaminating groundwater. the contamination vulnerability and groundwater protection assessment has proved to be an effective tool for the delineation of protection zones in area affected by groundwater contamination. the main objective of the study is to evaluate aquifer pollution vulnerability in the new waste disposal sit...

The contamination of groundwater by heavy metal, originating either from natural soil sources or from anthropogenic sources is a matter of utmost concern to the public health. Remediation of contaminated groundwater is of highest priority since billions of people all over the world use it for drinking purpose. In this paper, thirty five approaches for groundwater treatment have been reviewed an...

prediction of the heavy metals in the groundwater is important in developing any appropriate remediation strategy. this paper attempts to predict heavy metals (pb, zn and cu) in the groundwater from arak city, using artificial neural network (ann) algorithm by taking major elements (hco3, so4) in the groundwater from arak city. for this purpose, contamination sources in the groundwater were rec...

Concentrations of heavy metals (As, Co, Cu, Ni, Mo, Pb and Zn) are studied in the soil of Shiraz industrial complex zone, south Shiraz, Iran to asses metal contamination due to industrialization, urbanization and agricultural activity. Soil samples were collected from three different depths. The A and C depths are enriched with metals such as Ni, As, Mo, Cu, Pb and Zn, compared with the B depth...

abstract soil contamination with heavy metals is a serious problem in all over the world. soils are contaminated by many different sources of heavy metals. currently different methods are used by researchers for identifying heavy metal contamination. assessing soil metal toxicity with bacterial bioluminescence is one of the new techniques. in this study, different concentrations of zinc and cop...
