... A case study of soil contamination assessment and clean-up in a site proposed for residential development is presented in this paper. The contamination consists mainly of heavy metals of which lead is the most important contaminant. The site has been sampled on an approximately 25 × 25 square...

The studies also showed the flux data are useful for inferring the extent and direction of contamination where limited hydrological data are available. soil contamination ground-water contamination vadose zone static trapping...

... A multilaboratory test program to determine lead content in soils produced aberrant results from two laboratories and indicated apparent problems with sample preparation. The program demonstrates the importance of quality control in remedial site investigation to determine soil contamination...
