Paper Number: ISRM-IS-2000-111
... ABSTRACT: Soil and groundwater can be easily contaminated by the infiltration of landfill leachate and petroleum hydrocarbons. Leakage of leachate and petroleum hydrocarbons is induced from the damage of liners or underground storage tanks(USTs). Leakage detection system can be effectively...

... been made to examine the concentration level of contaminants present in the marine sediments collected at Changi coast. Test results indicated low concentrations of metals, and they are within the permissible limits. X-ray diffraction (XRD) and Scanning electron microscopy (SEM) techniques have been...

...) and resistivity applied at a site in Rio De Janeiro, Brazil, where the soil and groundwater were contaminated by an organochloride pesticide called HCH hexachlorocyclehexane, and by metabolotes. Detailed hydrogeological and some geological information is available for the site and is summarized in this report...

...THE USE OF ALTERNATIVES TO ACTIVATED CARBON FOR THE CLEAN UP OF CONTAMINATED GROUNDWATER Fiona M. Parker1, David W. Smith2, Phillip W. Hitchcock3 ABSTRACT This paper assesses possible alternatives to the use of activated carbon for the clean up of aqueous phase contaminants. The physical properties...

... INTRODUCTION: Increasingly it is realized that, under economical and ecological aspects, conventional pump-and-treat systems for remediation of contaminant plumes do not lead to satisfying results. This is particularly true if remediation periods of several decades are anticipated, which means...

... ABSTRACT: There are two forms of soil remediation methods, in-situ and ex-situ methods. This project is related to one group of in-situ methods, namely reactive wall technologies. This involves the placement of material in a trench downstream of the contaminant plume. The contaminant is swept...
